    Definitions -> L -> Leap Year

 Leap Year


A leap year is a year containing an extra day. It has 366 days instead of the normal 365 days.

The extra day is added in February, which has 29 days instead of the normal 28 days.

Leap years occur every 4 years. 2008 is a leap year and so is 2012.

Except that every 100 years special rules apply. For example 1900 was not a leap year, but 2000 was.
