When is leap April?

2020 is a leap April. A year with a leap month in the lunar calendar is called a leap month year, but now it is also customarily called a leap year (so it is easily confused with a leap year in the Gregorian calendar). The general year is 12 months, 354 or 355 days, and the leap year is 13 months, 383 or 384 days. There is no thirteenth month in the lunar calendar. According to the calendar rules, leap months are repeated in the same month from February to 10, and the repeated months are leap months. For example, the leap month after April is called leap April. The law of lunar leap year is a leap every three years, a leap every five years, and a leap of 19. According to the laws of the lunar calendar, it is mainly determined according to the coincidence with the 24 solar terms of the lunar calendar. Usually, a month with only one solar term (usually a small month) is set as a leap month to make up for it. The number of leap months in the lunar calendar is the same as that in normal months, both of which are 29 or 30 days. The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. For example, in the Gregorian calendar, May 27th, 200 1, May 27th 1982 and May 27th 1963 are the fifth day of leap April.
