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.
Say You still have two statements, one is the ordinary hot spot, one is the century leap year, is this year is to meet 400 times, is the century leap year, for example, 2000 is the most classic century leap year, but leap years have no special meaning.
In the run-year, February has only 28 days, which can supplement the time difference caused by the Earth’s revolution during these years.
It is precisely because of this law that people’s chronology legislation is still relatively scientific, and this statement has been recognized by the whole world, and now all countries in the world use the same calendar.
In the past, there were many special customs about the hot year, but now the society is relatively open, and there are not so many feudal superstitions. Naturally, there is no need for any special rituals in leap years.
