The Doomsday algorithm for calculating the day of the week makes use of the fact that in each year,
4 April (4/4) 6 June (6/6) 8 August (8/8) 10 October (10/10) and 12 December (12/12)
are all the same day of the week. This day of the week is called Doomsday. The algorithm also defines 9/5 and 7/11 and their reverses to be Doomsday.
The Doomsday algorithm was invented by John Horton Conway.
