The below is an abridged ] of events established in the group of ]s and ]s set in the ] ] universe. More exhaustive timelines are available in both ] and in various ] websites.
This article discusses the fictional '''timeline of the '']'' franchise'''. The franchise is primarily set in the future, ranging from the mid-22nd century ('']'') to the late 24th century ('']''), with the third season of '']'' jumping forward to the 32nd century. However the franchise has also outlined a fictional ] of Earth prior to this, and, primarily through ] plots, explored both past and further-future settings.


The chronology is complicated by the presence of divergent timelines within the franchise's narrative, as well as internal contradictions and ]s. The ] generally avoided assigning real-world dates to its futuristic setting, instead using the ] system. Series from '']'' onwards defined their temporal settings in conventional form.
==History of the chronology==


==Series, books, and film settings==
There have been several efforts over the years to develop a chronology for the events depicted by the ] television series and its spin-offs. This matter has been complicated by the continued additions to the Star Trek canon.
This table shows each TV series and movie, its year of release or broadcast, the year it was set in according to the prevailing Okuda chronology (see below), and the ] range for that year. The designation '']''-based series are the series that featured the various incarnations of the starship USS ''Enterprise''. In universe timeline chronological order '']'' (ENT), '']'' (TOS), '']'' (TAS), '']'' (TNG), and all 13 of the ''Star Trek'' feature films, including the three newest ] "reboot" films, or "Kelvin Timeline" based on the original series.{{citation needed|date=December 2019}}

===Timeline in order of series air dates===
There are few references setting the original series in an exact timeframe, and those that exist are largely contradictory :
{{Timeline of Star Trek franchise}}


==Chronology and events==
*In the episode "]" is said that Khan was from "two centuries" ago (1996), placing the episode in the late 22nd century
This timeline is based on the ''Star Trek Chronology'' model described below, supplemented by data from the website ].<ref name=okuda /> The Timeline also consists of before, between, and after those events.
*In the episode "]", it is said that 1960 was around 300 years ago
*The episode "]" implies that the ] of 19th century Earth has expanded to 800 years, setting the episode in the 27th century.
*In the episode "]", Kirk states that is it is Thanksgiving on Earth (the United States Thanksgiving festival is held in late November)


Note: Many of these dates are rounded-off approximations, as the dialog from which they are derived often includes qualifiers such as "over," "more than," or "less than."
===Spaceflight chronology===

Within the TNG era, episodes are easier to date. Stardates correspond exactly with seasons, with the first two digits of the stardate representing the season number. Okuda assumes the start of a season is January 1 and the end of the season is December 31.
* c. 2540–2550
** The Starship ''Enterprise''-J (presumably NCC 1701-J) is commissioned and takes part in the Battle of Procyon V against the Sphere Builders as shown in '']'' episode "Azati Prime". As the events of the episode “Zero Hour” result in the destruction of the spheres and the dissipation of the altered space, it is likely this battle occurs only in an alternate timeline.

In First Contact, Zephram Cochrane is confirmed as having invented warp drive, but the date is moved forward slightly to 2063, and it is revealed that first contact with the Vulcans took place immediately afterwards as a result of this.
* The Aeon-type timeship is in active service during this century ("]"), as is the ''Wells''-class timeship ''Relativity'' ("]").


===30th century===
Enterprise is set in the 2150s, and ties into the Cochrane backstory. Its pilot, "]", depicts first contact with the Klingons, occurring much earlier than the Okuda chronology anticipated. It shows the opening of the Romulan war and the start of a coalition between Earth, Vulcans, Andor and Tellar. The final episode, "]", finally confirms 2161 as the founding year for the Federation.
* Around the year 2958, supplies of Dilithium in the Milky Way started to dry up, marking the beginning of an energy crisis. The ] began development and trials of alternatives to warp drive, though none proved to be reliable.
* The Federation spends much of this century engaged in a temporal war with the objective of upholding the Temporal Accords to ensure the timeline remains unaltered.


==Timeline== ===31st century===

** A cataclysmic galaxy-wide event referred to as "The Burn" occurs. Nearly all dilithium in the galaxy suddenly goes inert, causing a massive loss of life and the destruction of every ship and facility with an active warp core.

(This occurred in the second-season Voyager episode "Death Wish.")


==History of the chronology (historiography)==
===5 Billion (possibly earlier) - 3.5 Billion Years Ago===
Several efforts have been made to develop a chronology<ref>{{cite web |url=http://thestartrekchronologyproject.blogspot.com/2009/09/and-now-we-present-complete-star-trek_19.html|title=And now we present the complete Star Trek Canon in chronological order! ENJOY!!!|date=2009-09-19|website=The Star Trek Chronology Project}}</ref> for the events depicted by the '']'' television series and its spin-offs. This matter has been complicated by the continued additions to the ''Star Trek'' canon, the existence of time travel and multiple concurrent timelines, and the scarcity of ] dates given in the show (]s instead being used).
*The ] is created. (The Guardian claims in the first-season TOS episode ] to have been built before the formation of Earth's solar system, so it is ''at least'' 5 billion years old.)


===Original series===
*A humanoid civilization seeds the oceans of many planets, which gives rise to many races, including humans, ], ], and ]. (This was revealed in the sixth-season TNG episode ])
Not many references set the original series in an exact time frame, and those that exist are largely contradictory. In the episode "]", a 1960s military officer says that he's going to lock ] up "for two hundred years", to which Kirk replies, with wry amusement: "That ought to be just about right." Likewise, in the episode "]", it is said that the 1996 warlord ] is from "two centuries" ago. Both these references place the show in the 22nd century. However, in the episode "]", it is said that 1960 was around 300 years ago, pushing the show into the 23rd century. Finally, the episode "]" implied that the ] of 19th century Earth has expanded to 900 light years of radius, which seems to set the show in the 28th century, since light would take nine centuries to traverse that distance.


According to notes in ''The Making of Star Trek'', the show is set in the 23rd century, and the ''Enterprise'' was supposed to be around 40 years old. Roddenberry says in this book that the stardate system was invented to avoid pinning down the show precisely in time frame.<ref name=making>{{cite book|title=The Making of Star Trek|year=1968|publisher=Ballatine Books|author1=Whitfield, Stephen E |author2=Roddenberry, Gene |name-list-style=amp }}</ref> Roddenberry's original pitch for the series dated it "'somewhere in the future.

The '']'' game was published in 1979, with a license only covering the original series. It has since diverged into an entirely separate fictional universe, new additions to which continue to be published. It does not tie into the Gregorian calendar, instead using a "Year 1" of the invention of Warp on Earth. Its version of the original series backstory is:
===87 Million Years Ago===
* Y1&nbsp;– Warp drive is developed on Earth.
*A civilization in the D'Arsay system launches a robotic interstellar archive of their culture. (The Enterprise-D crew come across the archive in the seventh-season TNG episode "Masks".)

===600,000 Years Ago=== ===TNG era and Okuda===
Press materials for ''The Next Generation'' suggested it was set in the 24th century, seventy-eight years after the existing ''Star Trek'', although the exact time frame had not yet been set in stone. The pilot had dialogue stating Data was part of the Starfleet "class of '78".<ref name=companion>{{cite book|title=Star Trek: The Next Generation Companion|publisher=Pocket Books|year=2003|author=Nemeck, Larry|isbn=0-7434-5798-6}}</ref> The pilot episode, "]", also has a cameo appearance by ], who is said to be 137.
*The Tkon Empire, whose members number in the trillions, goes extinct when their sun goes supernova. (] described the empire in the first season TNG episode ].)


In the last episode of the first season, the year is firmly established by ] as 2364.<ref name=companion /> This marked the first time an explicit future calendar date had been attached to a ''Star Trek'' storyline, and allowed fans and writers to extrapolate further dates. For example, the established date implies McCoy was born around 2227, ruling out the ''Spaceflight Chronology''-derived dating of the original series to the early 23rd century (though the dating had already been effectively overruled by ''Star Trek IV'', which primarily takes place in 1986, where Kirk tells Gillian Taylor that he is from the late 23rd century, though he does not give an exact date).
*Sargon's people explore the galaxy and found colonies on other planets. (Sargon said this to ] in the second-season TOS episode "].")

===500,000 Years Ago (possibly earlier)===
*The ancient ] flourish, producing lasting works of ], ], and ], before humans even ]. (Picard mentioned this in the fifth-season TNG episode ].)


It gives the following dates:
*The star Exo, parent to the planet Exo III, begins to fade. The Exosians react by immigrating underground, and as a result their culture becomes more mechanized, with androids becoming commonplace in society. When the Exosians began to fear the androids, they attempted to deactivate them, and in defense, the ] exterminated the Exosians. (] mentioned the date when the star began to fade in the first-season TOS episode "What Are Little Girls Made Of?")
* Zephram Cochrane invents warp drive around 2061 (so that the SS ''Valiant'' can be constructed and go missing two hundred years before "]", dated to 2265; the first edition gives 2061; the second edition moves this to 2063 per '']'').
* The Romulan War takes place in the 2150s (about a hundred years before "]").
* The Federation is formed in 2161, after the Romulan War, on the basis that "Balance of Terror" says that it was an Earth-Romulan war, not a Federation-Romulan War.
* The first Constitution-class starship is launched in 2244, followed by the ''Enterprise'' in 2245.
* Kirk's ] lasts from 2264 to 2269, based on the assumption that the original series is set exactly 300 years after its original broadcast.
** Aired live-action ''Star Trek'' episodes are dated from 2266 to 2269. The chronology does not include the events of '']''. This is in keeping also with Gene Roddenberry's concept (discussed in ''The Making of Star Trek'' by Roddenberry and Stephen Whitfield) that ''Star Trek's'' first season takes place after the mission has been under way for some time.
** An episode of '']'', "]", aired after the ''Chronology'' was published, established that Kirk's five-year mission actually ended in 2270.
* The events of '']'' take place in 2271 (Kirk has been Chief of Starfleet Operations for {{frac|2|1|2}} years, according to dialog from Kirk and Decker).
** The "]" dating for Kirk's five-year mission, moves the first film to c. 2273.
* Numerous sources, including the ''Chronology'', postulate a second five-year mission under now-Admiral Kirk's command, begun soon after the events of the first movie; in part this is to take into account the unproduced revival series ].
* The events of '']'' and '']'' take place in 2285.
** ''The Wrath of Khan'' is a sequel to the episode "Space Seed", which Okuda dates to 2267. In Okuda's timeline there is a gap of eighteen years rather than the fifteen years established in dialog. The film was released in 1982, fifteen years after the episode's broadcast in 1967. The film begins on Kirk's birthday, which is semi-canonically established as March 22, the same as ]'s.
* The events of '']'' take place in 2286.
** This places ''Star Trek III'' in late 2285, as Kirk states in his log that the ''Enterprise'' crew has been on Vulcan for "three months" since bringing Spock home.
* The events of '']'' apparently take place soon after the events of the fourth film, as evidenced by Scotty's complaints about repairing the ship after its shakedown cruise, which was depicted at the end of ''Star Trek IV''. ''Star Trek V'' would then take place in early 2287.
* The events of '']'' take place in 2293, based on McCoy's statement that he had served on the ''Enterprise'' for 27 years, and his absence in "]".
* The Kirk-era part of '']'' is set 78 years before 2371 (established by way of an on-screen caption), thus is set in 2293 and soon after ''Star Trek VI''.


The gap between the 1986 film ''Star Trek IV: the Voyage Home'' (2286) and the 1987 first season of ''The Next Generation'' (2364) is 78 years by this timeline, matching early press materials.
*A cataclysm on Sargon's planet rips away its atmosphere, leaving the planet almost totally dead, with few survivors left in suspended animation deep below the surface. (Spock noted the date of the disaster in the second-season TOS episode "Return to Tomorrow".)


A gap of 10 years passed between the broadcast of the last episode of ''Star Trek: The Original Series'' and the release of ''The Motion Picture''. The film skirted around the fact the actors had aged, supposing that only {{frac|2|1|2}} years had passed since the events of the TV show. For ''Star Trek II'', it was decided to acknowledge the reality of the aging actors, both by setting the film some 15 years after "Space Seed", and by having Kirk worry about getting old.<ref>{{cite book|title=From Sawdust to Stardust|author=Terry Lee Rioux|isbn=978-0-7434-5762-0|publisher=Pocket Books|year=2005}}</ref>
*The inhabitants of Talos IV are almost completely destroyed in a war, and the planet becomes virtually uninhabitable. The survivors move underground but find the confines of subterranean life constricting, and they increasingly rely on telepathic illusions for entertainment.


Within ''The Next Generation'' era, episodes and films are easier to date. Stardates correspond exactly with seasons, with the first two digits of the stardate representing the season number. Okuda assumes the start of a season is January 1 and the end of the season is December 31.<ref name=okuda /> ''The Next Generation'', ''Deep Space Nine'', and ''Voyager'' television series, as well as the movies, have roughly followed "real time", and are set around 377 years after their release.
===200,000 Years Ago===
* The ancient Iconian civilization flourishes, becoming a strong influence on many other cultures, including the Dewan, the Iccobar, and the Dinasian. The Iconians were known by others as "Demons of Air and Darkness" for their ability to use their dimensional gateways for transportation, allowing them to cross interstellar distances and appear on other planets, a tactic claimed by the people who destroyed Denius III to have been used to expand thier empire. (Captain Donald Varley described the archaeological evidence from Denius III in the second-season episode "Contagion".)


Since the ''Chronology'' was published, it has been generally adhered-to by the producers of the show. The film '']'' and prequel series '']'' both revisit the early era. In ''First Contact'', Zephram Cochrane is confirmed as having invented warp drive on Earth, but the date is moved forward slightly to 2063, and it is revealed that Earth's official first contact with an alien species, the Vulcans, took place immediately afterwards as a result of this.
===50,000 Years Ago===
*The silicon-based lifeform indigenous to Janus VI known as the Horta begin their most recent cycle of rebirth, which involves every member of that species dying, save for one who guards the eggs of the next generation, located beneath the surface of the planet. (Spock’s mind-meld with the Horta revealed this in the first-season TOS episode "The Devil in the Dark.")


The dating of the final season of '']'' has presented controversy. The standard assumption about stardates, as well as the regular correspondence between seasons and in-universe years, would place the entire season in the year 2377; the season begins with stardate 54014.4 and ends with 54973.4. However, the episode "]" features a celebration of the 315th anniversary of ]'s first contact with the ], which would set the episode on April 5, 2378. The fansite ] thus places the final eight episodes of the season ("]" through "]") in 2378, with other sources following suit.
*Lokai, of the planet Cheron, attempts to lead a revolution against that planet’s government for what his people perceived as racial injustice and oppression. After being convicted of treason, he fled the planet, and was pursued by Commissioner Bele. (Bele explained their backstory to Kirk’s crew in the third-season TOS episode "].")


'']'' is set in the 2150s, and ties into the Cochrane backstory. The show uses the ] instead of Stardates, making tracking the dating easier. Its pilot, "]", depicts first contact with the Klingons occurring much earlier than the Okuda chronology anticipated (it suggested a date of 2218, based on a line in "]", noting that dialog in ] makes this problematic&nbsp;– though the actual line in the episode referred to ''hostilities'' between the two, and in '']'', Human-Klingon relations, while by no means friendly, clearly do not rise to the de facto state of war shown in ''TOS''). It shows the opening of the Romulan war and the start of a coalition between Earth, Vulcan, Andor, and Tellar in the 2150s. The date of the founding year of the Federation, 2161, was revealed in the fifth-season ''TNG'' episode "The Outcast," based on an early draft of the Okuda timeline. The final episode of '']'', "]", is consistent with the establishment of 2161 as the founding year for the Federation.
*The planet-killer, or Doomsday Machine, built as an ultimate weapon which could destroy both sides in an unknown conflict, begins its journey of destruction. It is finally destroyed in 2267 by the ''U.S.S. Constellation''.


No version of the ''Chronology'' or the ''Encyclopedia'' has been published since 1999. A 2006 book by ] contains a timeline which attempts to date all of the many ].<ref>{{cite book|title=Voyages of the Imagination: The Star Trek Fiction Companion|publisher=Pocket Books|year=2006|isbn=1-4165-0349-8|author=Ayers, Jeff}}</ref> This timeline has ''The Motion Picture'' in 2273, to account for the two-and-a-half-year gap between the end-date of 2270 established in "Q2" and the events of the movie.

===45,000 Years Ago===
*A group of extraterrestrials from the ] visited ancient humans in Earth’s ], who called them the "Sky Spirits." The Sky Spirits gave these humans, whom they called the "Inheritors," a genetic bonding to help them and their world survive. (The "Sky Spirit" related the story to ] in the second-season ''Voyager'' episode "Tattoo.")


===Eugenics Wars and World War III===
*A ceramic figurine called a naiskos is created on the planet Kurl. (Professor Galen gives the artifact to Captain Picard in the fifth-season TNG episode ].)
When the original series of ''Star Trek'' was produced, the 1990s were several decades away, and so various elements of the backstory to ''Star Trek'' are set in that era, particularly the Eugenics Wars. The references to the Eugenics Wars and to a nuclear war in the 21st century are somewhat contradictory.


The episode "]" establishes the Eugenics Wars, and has them lasting from 1992 to 1996. The Eugenics Wars are described as a global conflict in which the progeny of a ] project, most notably ], established themselves as supermen and attempted ]. Spock calls them "the last of your so-called World Wars", and McCoy identifies this with the Eugenics Wars.
===30,000 Years Ago===
*The Verathan civilization in the Gamma Quadrant reaches its height, spanning two dozen star systems. (] stated this in the first-season ] episode ].)


In the episode "]", Spock gives a death toll for World War III of 37 million. The episode "]" features a ], who led a genocidal war in the 21st century. The ''TNG'' episode "]" further establishes a "post-atomic horror" on Earth in 2079. However, the movie ''Star Trek: First Contact'' put the contact between Vulcans and humans at April 5, 2063.
===25,000 Years Ago===
*The Trill begin their symbiotic relationships as a joined species which pairs an intelligent vermiform creature with a humanoid host.


The '']'' identifies the "Bread and Circuses" figure as the death toll for a nuclear ], in the mid-21st century. '']'' firmly establishes World War III ended, after a nuclear exchange, in 2053, but with a body count of 600 million. The figure of Colonel Green is elaborated on in '']''.

*The first of 947 archeological expeditions begin to the ruins on planet Tagos III. (Picard referenced this date in the fourth-season TNG episode ].)


The ''Voyager'' episode "]" saw the ''Voyager'' crew time-travel to ] in 1996, which, as the ''Encyclopedia'' notes, seems entirely unaffected by the Eugenics Wars, which ended that year. The episode acknowledges the issue only by featuring a model of Khan's DY-100-class ship on a 1996 desk.<ref name=encyclopedia>{{cite book|title=]|last1=Okuda|first1=Mike|first2=Denise|last2=Okuda|last3=Mirek|first3=Debbie|publisher=Pocket Books|isbn=0-671-53609-5|year=1999}}</ref> Khan's spaceship is another anomaly for the timeline, which has a variety of long-lost spaceships being launched between 1980 and 2100, with inconsistent levels of technology (caused by the increasing real lifetime and also decreased optimism about the pace of space exploration).

*The machine-god Vaal is built on the planet Gamma Trianguli VI in order to provide food and climate control for the Triangulians. (] noted that the Triangulians had no progress for "at least ten thousand years," in the second-season TOS episode "]," suggesting that Vaal was created ''at least'' that long ago.)


A reference in the ''Deep Space Nine'' episode "]" suggests that the Eugenic Wars instead took place in the 22nd century. According to writer ], this was not an attempt at a ], but a mistake&nbsp;– when writing the episode, he recalled the already questionable "two centuries ago" line from "Space Seed" and forgot that ''DS9'' takes place over 100 years later.<ref>{{cite web|url=http://www.geocities.com/Hollywood/6952/ron5.txt|title=Answers|date=1997-03-03|author=Ronald D.

*The Fabrini sun goes nova, destroying the planets in that system. The Fabrina anticipated this event by creating a giant interstellar ark called Yonada out of a 200-mile-diameter asteroid in which to survive a 10,000 year voyage to a planet near Daran V. (Spock noted the date in the third-season TOS episode ])


Season 4 of '']'' involves a trilogy of episodes ("]", "]", and "]") related to scientist Doctor ], ancestor of Doctor ], and his genetic augmentations of Humans. Numerous historical details of the devastating Eugenics Wars are discussed: the death of 35–37 million people; how Earth's governments could not decide on the fate of the 1,800 genetically enhanced embryos; and how Soong had infiltrated the complex and stolen and raised 19 embryos himself. Soong maintained that he himself and humanity in general had learned the lessons of the Eugenics Wars and should not continue to hide behind those events when there was progress to be made now that the technology had matured and was much more practicable. (The actions of his "children" convince him otherwise, and at the end of "The Augments" Soong declares his interest in cybernetics, beginning the work which would one day bring about ].)
*The Q Continuum begin a new era of exploration, discovery, learning, and dialog from knowledge gleaned across the universe. (So noted in the second-season '']'' episode Death Wish.”)


]'s two-book series '']'' develops the idea of the Eugenics Wars in the context of real-life history by representing it as a ], and that the truth behind the various civil wars and conflicts in the 1990s was not generally known; Los Angeles, whose appearance in "Future's End" helped bring the war's existence into question, is portrayed as an EW "battlefront", the ] being one such calamity.
*The ] capitalist society is established, with ] Gint, the first Grand Nagus, codifying Ferengi law and business in the ]. (Noted in the fourth-season ''DS9'' episodes "Bar Association" and "Body Parts.")


The series ''],'' which first aired in spring 2022, complicates the timeline further by retconning certain dating aspects by explicitly dating the Eugenics Wars to the first half of the 21st century (for example, the episode "Tomorrow and Tomorrow and Tomorrow" features a young Khan Noonien-Singh, long before his insurrection, and is set in the 2020s), following a second American Civil War and leading up to the full-scale World War III nuclear conflict described in earlier films and episodes. This differs from "Space Seed" asserting that not only did the Eugenics Wars take place in the mid-1990s but dialogue indicates that they were either concurrent with or simply were World War III.
*The first "]," hourglass-shaped crystal-like objects, is discovered by the ancient Bajorans in the skies of Bajor, the first of ten to be discovered over the next 10,000 years, which inspire Bajoran theology. (] noted the date to ] in the DS9 pilot episode, ])


===Cochrane===
*The Kalandan outpost, an artificial planet, is deployed.
In the episode "]", it is stated that ] of Alpha Centauri, the discoverer of the space warp, disappeared 150 years ago, at the age of 87. Based on the 2207 to 2212<ref name=mr_scott /> <!-- page 12 ---> date originally given this would have put Cochrane's disappearance between 2057 and 2062 and his birth between 1970 and 1975. However, Okuda's date of 2267 for that episode, puts Cochrane's disappearance in 2117 and birth in 2030. 1980s spin-off material such as the '']'' posit that Cochrane was from Alpha Centauri originally, and that a sub-warp ship the UNSS ''Icarus'' arrived at Alpha Centauri in 2048 to find he had discovered the theory behind warp drive. The ''Icarus'' then relayed its findings back to Earth. The first prototype warp ship was launched in 2055.


The ''Star Trek Chronology'' does not hold with this theory, and asserts that Cochrane was an Earth native, who moved to Alpha Centauri later in life. (Even in "Metamorphosis", before Cochrane identifies himself to the landing party, Dr. McCoy had taken a tricorder scan and determined him to be human.) The first edition ''Chronology'' notes that Cochrane's invention of warp drive must have been at least 200 years before "]", and suggests a date of 2061, noting that Cochrane would be 31 that year.
===6,000 Years Ago===
*Landru, leader of the planet Beta III in star system C-111, creates a powerful computer featuring holograms in his likeness and all of his stored knowledge in order to care for his people after his death. (Spock noted the date in the first-season TOS episode "Return of the Archons.")


The film '']'' prominently features Cochrane's first successful warp flight. The film is set in 2063, two years after the ''Chronology'' suggestions, and therefore by the timeline Cochrane is 33. The actor who played Cochrane in that movie, ], was 56 at the time of the film's release. The ''Encyclopedia'' notes the age issue, and claims that the Cromwell Cochrane had suffered from radiation poisoning, causing his aged appearance. '']'' pins down Cochrane's disappearance to 2119, making Cochrane instead 31 at the time of ''First Contact''.
*Unidentified aliens take several humans from Earth to be raised on a distant planet. Their descendants are trained so that they can be returned to Earth to prevent humans from destroying themselves. (] described this in the TOS second-season finale, ].)

Because the habitat provided for the Ocampa’s every need, most of the Ocampa's powerful psionic abilities atrophied (this was described in the '']'' pilot episode ].

This article discusses the fictional timeline of the Star Trek franchise. The franchise is primarily set in the future, ranging from the mid-22nd century (Star Trek: Enterprise) to the late 24th century (Star Trek: Picard), with the third season of Star Trek: Discovery jumping forward to the 32nd century. However the franchise has also outlined a fictional future history of Earth prior to this, and, primarily through time travel plots, explored both past and further-future settings.

The chronology is complicated by the presence of divergent timelines within the franchise's narrative, as well as internal contradictions and retcons. The original series generally avoided assigning real-world dates to its futuristic setting, instead using the stardate system. Series from Star Trek: The Next Generation onwards defined their temporal settings in conventional form.

Series, books, and film settings

This table shows each TV series and movie, its year of release or broadcast, the year it was set in according to the prevailing Okuda chronology (see below), and the stardate range for that year. The designation Enterprise-based series are the series that featured the various incarnations of the starship USS Enterprise. In universe timeline chronological order Star Trek: Enterprise (ENT), Star Trek: The Original Series (TOS), Star Trek: The Animated Series (TAS), Star Trek: The Next Generation (TNG), and all 13 of the Star Trek feature films, including the three newest J. J. Abrams "reboot" films, or "Kelvin Timeline" based on the original series.

History of the chronology (historiography)

Several efforts have been made to develop a chronology for the events depicted by the Star Trek television series and its spin-offs. This matter has been complicated by the continued additions to the Star Trek canon, the existence of time travel and multiple concurrent timelines, and the scarcity of Gregorian calendar dates given in the show (stardates instead being used).

Original series

Not many references set the original series in an exact time frame, and those that exist are largely contradictory. In the episode "Tomorrow Is Yesterday", a 1960s military officer says that he's going to lock Captain Kirk up "for two hundred years", to which Kirk replies, with wry amusement: "That ought to be just about right." Likewise, in the episode "Space Seed", it is said that the 1996 warlord Khan Noonian Singh is from "two centuries" ago. Both these references place the show in the 22nd century. However, in the episode "Miri", it is said that 1960 was around 300 years ago, pushing the show into the 23rd century. Finally, the episode "The Squire of Gothos" implied that the light cone of 19th century Earth has expanded to 900 light years of radius, which seems to set the show in the 28th century, since light would take nine centuries to traverse that distance.

According to notes in The Making of Star Trek, the show is set in the 23rd century, and the Enterprise was supposed to be around 40 years old. Roddenberry says in this book that the stardate system was invented to avoid pinning down the show precisely in time frame. Roddenberry's original pitch for the series dated it "'somewhere in the future. It could be 1995, or maybe even 2995".

Early chronologies

The Star Trek Spaceflight Chronology and FASA, a publisher of the first licensed Star Trek role-playing game, chose to take the "Space Seed figure", adding a few years to make sure the events of the Original Series were in the 23rd century. This dating system is followed by other spin-off works in the 1980s, including Mr. Scott's Guide to the Enterprise. This timeline system gives the following dates

  • The sub-warp ship the UNSS Icarus makes first contact with Alpha Centauri in 2048, and there meets Zefrem Cochran , who has invented warp drive.
  • The first Earth warp ship, the Bonaventure makes its first voyage, to Tau Ceti, in 2059.
  • The first contact with Vulcans is in 2065, when a damaged Vulcan spaceship is rescued by UNSS Amity.
  • The Federation is formed in 2087.
  • The Earth–Romulan War occurs in the 2100s.
  • First contact with the Klingon Empire in 2151, who demand the return of a group of refugees from the USS Sentry.
  • The first Constitution-class starship is launched in 2188.
  • The USS Enterprise's five-year mission under Captain Kirk lasts from 2207 to 2212.
  • The events of Star Trek: The Motion Picture occur in 2217.
  • The events of Star Trek II: The Wrath of Khan occur around 2222 (dialogue in the film says it is set "fifteen years" after the Season One episode "Space Seed").
  • The events of Star Trek IV: The Voyage Home occur on September 21, 2222.

The Star Fleet Battles game was published in 1979, with a license only covering the original series. It has since diverged into an entirely separate fictional universe, new additions to which continue to be published. It does not tie into the Gregorian calendar, instead using a "Year 1" of the invention of Warp on Earth. Its version of the original series backstory is:

  • Y1 – Warp drive is developed on Earth.
  • Y4 – Federation is formed by Earth, Vulcan, Andoria, Alpha Centauri.
  • Y40-Y46 – Earth–Romulan War.
  • Y71 – Starfleet is formed.
  • Y126 – The Constitution-class is launched (an upgrade from the Republic-class).
  • Y154–159 – The events of the Original Series.

See Star Fleet Universe timeline.

TNG era and Okuda

Press materials for The Next Generation suggested it was set in the 24th century, seventy-eight years after the existing Star Trek, although the exact time frame had not yet been set in stone. The pilot had dialogue stating Data was part of the Starfleet "class of '78". The pilot episode, "Encounter at Farpoint", also has a cameo appearance by Leonard "Bones" McCoy, who is said to be 137.

In the last episode of the first season, the year is firmly established by Data as 2364. This marked the first time an explicit future calendar date had been attached to a Star Trek storyline, and allowed fans and writers to extrapolate further dates. For example, the established date implies McCoy was born around 2227, ruling out the Spaceflight Chronology-derived dating of the original series to the early 23rd century (though the dating had already been effectively overruled by Star Trek IV, which primarily takes place in 1986, where Kirk tells Gillian Taylor that he is from the late 23rd century, though he does not give an exact date).

A Star Trek Chronology was published in 1993, written by production staff members Denise Okuda and Michael Okuda. A second edition was issued in 1996. Okuda originally drew up a timeline for internal use by writers, based on his own research and assumptions provided by Richard Arnold. The dates in the Chronology are consistent with the earlier Star Trek: The Next Generation Technical Manual.

It gives the following dates:

  • Zephram Cochrane invents warp drive around 2061 (so that the SS Valiant can be constructed and go missing two hundred years before "Where No Man Has Gone Before", dated to 2265; the first edition gives 2061; the second edition moves this to 2063 per Star Trek: First Contact).
  • The Romulan War takes place in the 2150s (about a hundred years before "Balance of Terror").
  • The Federation is formed in 2161, after the Romulan War, on the basis that "Balance of Terror" says that it was an Earth-Romulan war, not a Federation-Romulan War.
  • The first Constitution-class starship is launched in 2244, followed by the Enterprise in 2245.
  • Kirk's five-year mission lasts from 2264 to 2269, based on the assumption that the original series is set exactly 300 years after its original broadcast.
    • Aired live-action Star Trek episodes are dated from 2266 to 2269. The chronology does not include the events of Star Trek: The Animated Series. This is in keeping also with Gene Roddenberry's concept (discussed in The Making of Star Trek by Roddenberry and Stephen Whitfield) that Star Trek's first season takes place after the mission has been under way for some time.
    • An episode of Voyager, "Q2", aired after the Chronology was published, established that Kirk's five-year mission actually ended in 2270.
  • The events of Star Trek: The Motion Picture take place in 2271 (Kirk has been Chief of Starfleet Operations for 2+1⁄2 years, according to dialog from Kirk and Decker).
    • The "Q2" dating for Kirk's five-year mission, moves the first film to c. 2273.
  • Numerous sources, including the Chronology, postulate a second five-year mission under now-Admiral Kirk's command, begun soon after the events of the first movie; in part this is to take into account the unproduced revival series Star Trek: Phase II.
  • The events of Star Trek II: The Wrath of Khan and Star Trek III: The Search for Spock take place in 2285.
    • The Wrath of Khan is a sequel to the episode "Space Seed", which Okuda dates to 2267. In Okuda's timeline there is a gap of eighteen years rather than the fifteen years established in dialog. The film was released in 1982, fifteen years after the episode's broadcast in 1967. The film begins on Kirk's birthday, which is semi-canonically established as March 22, the same as William Shatner's.
  • The events of Star Trek IV: The Voyage Home take place in 2286.
    • This places Star Trek III in late 2285, as Kirk states in his log that the Enterprise crew has been on Vulcan for "three months" since bringing Spock home.
  • The events of Star Trek V: The Final Frontier apparently take place soon after the events of the fourth film, as evidenced by Scotty's complaints about repairing the ship after its shakedown cruise, which was depicted at the end of Star Trek IV. Star Trek V would then take place in early 2287.
  • The events of Star Trek VI: The Undiscovered Country take place in 2293, based on McCoy's statement that he had served on the Enterprise for 27 years, and his absence in "Where No Man Has Gone Before".
  • The Kirk-era part of Star Trek Generations is set 78 years before 2371 (established by way of an on-screen caption), thus is set in 2293 and soon after Star Trek VI.

The gap between the 1986 film Star Trek IV: the Voyage Home (2286) and the 1987 first season of The Next Generation (2364) is 78 years by this timeline, matching early press materials.

A gap of 10 years passed between the broadcast of the last episode of Star Trek: The Original Series and the release of The Motion Picture. The film skirted around the fact the actors had aged, supposing that only 2+1⁄2 years had passed since the events of the TV show. For Star Trek II, it was decided to acknowledge the reality of the aging actors, both by setting the film some 15 years after "Space Seed", and by having Kirk worry about getting old.

Within The Next Generation era, episodes and films are easier to date. Stardates correspond exactly with seasons, with the first two digits of the stardate representing the season number. Okuda assumes the start of a season is January 1 and the end of the season is December 31. The Next Generation, Deep Space Nine, and Voyager television series, as well as the movies, have roughly followed "real time", and are set around 377 years after their release.

Since the Chronology was published, it has been generally adhered-to by the producers of the show. The film Star Trek: First Contact and prequel series Star Trek: Enterprise both revisit the early era. In First Contact, Zephram Cochrane is confirmed as having invented warp drive on Earth, but the date is moved forward slightly to 2063, and it is revealed that Earth's official first contact with an alien species, the Vulcans, took place immediately afterwards as a result of this.

The dating of the final season of Star Trek: Voyager has presented controversy. The standard assumption about stardates, as well as the regular correspondence between seasons and in-universe years, would place the entire season in the year 2377; the season begins with stardate 54014.4 and ends with 54973.4. However, the episode "Homestead" features a celebration of the 315th anniversary of Zefram Cochrane's first contact with the Vulcans, which would set the episode on April 5, 2378. The fansite Memory Alpha thus places the final eight episodes of the season ("Human Error" through "Endgame") in 2378, with other sources following suit.

Enterprise is set in the 2150s, and ties into the Cochrane backstory. The show uses the Gregorian calendar instead of Stardates, making tracking the dating easier. Its pilot, "Broken Bow", depicts first contact with the Klingons occurring much earlier than the Okuda chronology anticipated (it suggested a date of 2218, based on a line in "Day of the Dove", noting that dialog in "First Contact" makes this problematic – though the actual line in the episode referred to hostilities between the two, and in Enterprise, Human-Klingon relations, while by no means friendly, clearly do not rise to the de facto state of war shown in TOS). It shows the opening of the Romulan war and the start of a coalition between Earth, Vulcan, Andor, and Tellar in the 2150s. The date of the founding year of the Federation, 2161, was revealed in the fifth-season TNG episode "The Outcast," based on an early draft of the Okuda timeline. The final episode of Enterprise, "These Are the Voyages...", is consistent with the establishment of 2161 as the founding year for the Federation.

No version of the Chronology or the Encyclopedia has been published since 1999. A 2006 book by Jeff Ayers contains a timeline which attempts to date all of the many Star Trek novels. This timeline has The Motion Picture in 2273, to account for the two-and-a-half-year gap between the end-date of 2270 established in "Q2" and the events of the movie. The official website, StarTrek.com, still gives the date of that movie as 2271.

Eugenics Wars and World War III

When the original series of Star Trek was produced, the 1990s were several decades away, and so various elements of the backstory to Star Trek are set in that era, particularly the Eugenics Wars. The references to the Eugenics Wars and to a nuclear war in the 21st century are somewhat contradictory.

The episode "Space Seed" establishes the Eugenics Wars, and has them lasting from 1992 to 1996. The Eugenics Wars are described as a global conflict in which the progeny of a human genetic engineering project, most notably Khan Noonien Singh, established themselves as supermen and attempted world domination. Spock calls them "the last of your so-called World Wars", and McCoy identifies this with the Eugenics Wars.

In the episode "Bread and Circuses", Spock gives a death toll for World War III of 37 million. The episode "The Savage Curtain" features a Colonel Phillip Green, who led a genocidal war in the 21st century. The TNG episode "Encounter at Farpoint" further establishes a "post-atomic horror" on Earth in 2079. However, the movie Star Trek: First Contact put the contact between Vulcans and humans at April 5, 2063.

The Star Trek Concordance identifies the "Bread and Circuses" figure as the death toll for a nuclear World War III, in the mid-21st century. Star Trek: First Contact firmly establishes World War III ended, after a nuclear exchange, in 2053, but with a body count of 600 million. The figure of Colonel Green is elaborated on in Star Trek: Enterprise. First Contact also deliberately describes the warring parties in World War III as "factions", not nations per se.

The Voyager episode "Future's End" saw the Voyager crew time-travel to Los Angeles in 1996, which, as the Encyclopedia notes, seems entirely unaffected by the Eugenics Wars, which ended that year. The episode acknowledges the issue only by featuring a model of Khan's DY-100-class ship on a 1996 desk. Khan's spaceship is another anomaly for the timeline, which has a variety of long-lost spaceships being launched between 1980 and 2100, with inconsistent levels of technology (caused by the increasing real lifetime and also decreased optimism about the pace of space exploration).

A reference in the Deep Space Nine episode "Doctor Bashir, I Presume?" suggests that the Eugenic Wars instead took place in the 22nd century. According to writer Ronald D. Moore, this was not an attempt at a retcon, but a mistake – when writing the episode, he recalled the already questionable "two centuries ago" line from "Space Seed" and forgot that DS9 takes place over 100 years later.

Season 4 of Star Trek: Enterprise involves a trilogy of episodes ("Borderland", "Cold Station 12", and "The Augments") related to scientist Doctor Arik Soong, ancestor of Doctor Noonien Soong, and his genetic augmentations of Humans. Numerous historical details of the devastating Eugenics Wars are discussed: the death of 35–37 million people; how Earth's governments could not decide on the fate of the 1,800 genetically enhanced embryos; and how Soong had infiltrated the complex and stolen and raised 19 embryos himself. Soong maintained that he himself and humanity in general had learned the lessons of the Eugenics Wars and should not continue to hide behind those events when there was progress to be made now that the technology had matured and was much more practicable. (The actions of his "children" convince him otherwise, and at the end of "The Augments" Soong declares his interest in cybernetics, beginning the work which would one day bring about Data.)

Greg Cox's two-book series The Eugenics Wars: The Rise and Fall of Khan Noonien Singh develops the idea of the Eugenics Wars in the context of real-life history by representing it as a secret history, and that the truth behind the various civil wars and conflicts in the 1990s was not generally known; Los Angeles, whose appearance in "Future's End" helped bring the war's existence into question, is portrayed as an EW "battlefront", the Rodney King riots being one such calamity.

The series Star Trek: Strange New Worlds, which first aired in spring 2022, complicates the timeline further by retconning certain dating aspects by explicitly dating the Eugenics Wars to the first half of the 21st century (for example, the episode "Tomorrow and Tomorrow and Tomorrow" features a young Khan Noonien-Singh, long before his insurrection, and is set in the 2020s), following a second American Civil War and leading up to the full-scale World War III nuclear conflict described in earlier films and episodes. This differs from "Space Seed" asserting that not only did the Eugenics Wars take place in the mid-1990s but dialogue indicates that they were either concurrent with or simply were World War III.

Cochrane

In the episode "Metamorphosis", it is stated that Zefram Cochrane of Alpha Centauri, the discoverer of the space warp, disappeared 150 years ago, at the age of 87. Based on the 2207 to 2212 date originally given this would have put Cochrane's disappearance between 2057 and 2062 and his birth between 1970 and 1975. However, Okuda's date of 2267 for that episode, puts Cochrane's disappearance in 2117 and birth in 2030. 1980s spin-off material such as the Star Trek Spaceflight Chronology posit that Cochrane was from Alpha Centauri originally, and that a sub-warp ship the UNSS Icarus arrived at Alpha Centauri in 2048 to find he had discovered the theory behind warp drive. The Icarus then relayed its findings back to Earth. The first prototype warp ship was launched in 2055.

The Star Trek Chronology does not hold with this theory, and asserts that Cochrane was an Earth native, who moved to Alpha Centauri later in life. (Even in "Metamorphosis", before Cochrane identifies himself to the landing party, Dr. McCoy had taken a tricorder scan and determined him to be human.) The first edition Chronology notes that Cochrane's invention of warp drive must have been at least 200 years before "Where No Man Has Gone Before", and suggests a date of 2061, noting that Cochrane would be 31 that year.

The film Star Trek: First Contact prominently features Cochrane's first successful warp flight. The film is set in 2063, two years after the Chronology suggestions, and therefore by the timeline Cochrane is 33. The actor who played Cochrane in that movie, James Cromwell, was 56 at the time of the film's release. The Encyclopedia notes the age issue, and claims that the Cromwell Cochrane had suffered from radiation poisoning, causing his aged appearance. Enterprise pins down Cochrane's disappearance to 2119, making Cochrane instead 31 at the time of First Contact.
