We all know that a leap year occurs every four years, so it is easier to calculate. As long as the Gregorian year is a multiple of 4 and not a multiple of 100, it is a leap year, which is relatively simple to calculate. The main purpose of leap years is to make up for the time difference between the speed of the earth’s revolution and people’s chronology.
