Judgment method of leap year

The Gregorian calendar rules for judging leap years are: leap every four years, not leap for a hundred years, and leap again every four hundred years.

Simple calculation method of leap year in Gregorian calendar: (A year that meets one of the following conditions is a leap year)

1。 Divisible by 4, but not by 100. (For example, 2004 is a leap year, but 1900 is not)

2。 Divisible by 400. (If 2000 is a leap year) The average annual length is 365.2425 days, with a deviation of about 4 years 1 day. According to a leap year every four years, the average annual increase will be 0.0078 days, which will be about 3 days after 400 years. So every 400 years, three leap years will be reduced. The calculation of leap year comes down to what is commonly said: leap every four years; Do not leap in a hundred years, and leap again in 400 years.
