List of leap years

List of leap years

In the Gregorian calendar, the current standard calendar in most of the world, most years that are divisible by 4 are leap years. In a leap year, the month of February has 29 days instead of 28. This compensates for the fact that a solar year is about 6 hours longer than 365 days, by adding an extra day to the calendar every four years.

However, the duration of a solar year is slightly "less" than 365.25 days, requiring some exceptions to this rule. Years which are divisible by 100 are "not" leap years, unless they are also divisible by 400, in which case they "are" leap years. [http://www.nmm.ac.uk/server/show/conWebDoc.349 Royal Observatory, Greenwich: Leap years] ] [http://aa.usno.navy.mil/faq/docs/leap_years.php USNO (U.S. Naval Observatory): Leap Years] ] For example, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. Going forward, 2100, 2200, 2300, 2500, 2600, 2700, 2900, and 3000 will not be leap years, but 2400 and 2800 will be. By this rule, the average number of days per year will be 365 + 1/4 − 1/100 + 1/400 = 365.2425, which is very close to the length of a solar year (approximately 365.2422 days).
