List of Leap Years from 1800 to 2500

A leap year is 366 days instead of the usual 365, with the extra day added to February, making it 29 days longer than 28. The purpose of leap years is to keep the calendar year synchronized with the astronomical year (the time it takes Earth to complete its orbit around the Sun), which is approximately 365.2425 days.

Leap Year Rule:

Leap Year Rule: A year is a leap year if it is divisible by 4. However, if the year is divisible by 100, it is not a leap year, unless it is also divisible by 400. This means that while 1600 and 2000 were leap years, 1700, 1800, and 1900 were not.

Reason for Leap Year: The solar year (the time Earth takes to orbit the Sun) is about 365.2425 days long, slightly longer than the 365 days used in the Gregorian calendar. Without leap years, the calendar would slowly drift out of alignment with the seasons.

Leap Year Cycle: A leap year occurs every 4 years, except for years divisible by 100 but not by 400. This results in a leap year cycle of 4 years, with exceptions every 100 years, unless the year is also divisible by 400.
