In order to synchronize the lunar calendar with the solar calendar in seasons, our ancestors adopted the method of "adding leap months" to "adjust the surplus and deficiency" and set seven leap months in 19, because the total number of days in the tropical year of 19 is basically equal to 19 plus seven leap months in the normal year.

Therefore, the lunar calendar stipulates a leap month every two or three years. In the year with leap month, the lunar calendar is 13 months, accounting for 383 days.

The following is the schedule of the leap March of the lunar calendar1993-2107 (115):

1993 leap March 203 1 leap March

206 1 leap March 2080 leap March

Leap March is two March in the lunar calendar year, and the second March is leap March. It is because the appearance of the sun and the moon is not caused by the number of whole days for the rotation period of the earth.

Leap March is a leap month with moderate frequency, sometimes once every 19 years, sometimes once every 8 years or once every 1 1 year.

The date of the Spring Festival in March is generally second only to the earliest year of the Spring Festival, and a few of the earliest years of the Spring Festival leap in March.
