A leap year contains 366 days rather than 365, the extra day is celebrated as February 29th. Leap years are those that are evenly divisible by four, unless the year is divisible by 100. An exception is made for centesimal years in which the year is divisible by 400. As a result, the Year 2000 is a leap year, since it is divisible by 400. | | Leap doy | mm dd | mm dd ----|-------|-------- 1 | 1 1 | 1 1 2 | 1 2 | 1 2 3 | 1 3 | 1 3 4 | 1 4 | 1 4 5 | 1 5 | 1 5 6 | 1
