Leap moon algorithm

Leap month is a kind of calendar leap, which means that one month is added every two to three years in the lunar calendar. In the lunar calendar, the moon revolves around the earth. In the lunar calendar, the length of the first month of the lunar calendar is 29.5306 days, which is the average of one month. The whole year is 65438+February, which is 10.88 days less than 365.2422 days in the tropic year. The product is a leap.

So leap for one month every three years, two months every five years and seven months every nineteen years. In this way, every month added in leap year is called leap month, and the leap month added after a certain month is called leap month. The leap month is set to coordinate the contradiction between the tropic year and the lunar year, and to prevent the lunar year and the tropic year, that is, the four seasons, from being out of touch.
