Year of century Flashcards
Learn the contribution of the year-of-century to the Doomsday sum, for years which are multiples of 4. Add the year-of-century value to the century value to compute the Doomsday for that year. For years that are not a multiple of 4, round down to the nearest multiple of 4, compute the Doomsday, and then add the remainder mod 4.
