leap year

A year that contains one more day than the usual calendar year so that the average length of the year is brought closer to the tropical year of 365.2422 days or to the lunar year. In the Julian calendar a leap year of 366 days occurred once every four years when the year was divisible by four. In the Gregorian calendar this rule was modified so that century years are leap years only when they are divisible by 400. The additional day is now added at the end of February (Feb. 29).

It offsets the difference between the length of the solar year (365.2422 days) and the calendar year of 365 days
