The Doomsday rule, Doomsday algorithm or Doomsday method is an algorithm of determination of the day of the week for a given date. It provides a perpetual calendar because the Gregorian calendar moves in cycles of 400 years. The algorithm for mental calculation was devised by John Conway in 1973, … See more Doomsday's anchor day for the current year in the Gregorian calendar (2024) is Tuesday. For some other contemporary years: The table is filled in horizontally, skipping one column for … See more Since this algorithm involves treating days of the week like numbers modulo 7, John Conway suggested thinking of the days of the week as "Noneday" or "Sansday" (for Sunday), "Oneday", "Twosday", "Treblesday", "Foursday", "Fiveday", and "Six-a-day" in order … See more For computer use, the following formulas for the anchor day of a year are convenient.
