Talk:Century leap year
A century leap year of the Gregorian calendar is the last year of any century that is divisible by 400, so other century years only divisible by 100 but not by 400 are common years. For example, 1600 and 2000 were century leap years; the century years of 1700, 1800, and 1900 were common years. The next century leap year will occur in 2400. Century leap years always start on a Saturday, and the resulting intercalation for February 29 is always a Tuesday.
