What year is leap month? What month is leap month?

The solar calendar is 365 a year. 2422 days; That is, the actual time when the earth moves around the sun. The four years in the solar calendar add up to one day, which is added at the end of February. For leap day. If there is a leap day in February, it is 29 days.

The lunar calendar is called the lunar calendar, with the "Yin, Wang, New Moon and Chord" of the moon as January. The lunar calendar is characterized by astronomical phenomena, about 30 days, and the small moon is 29 days, with 354 or 355 days a year.

In this way, the difference between the solar year and the lunar year is more than 1 1 day. In order to synchronize the lunar calendar with the solar calendar, our ancestors developed a leap month, which is added every two or three years (actually, it is a leap month in July of 19).

So there is 20 12 what you call leap April; 2065438+2004 leap in September, two leap in three years.

As for the arrangement of leap month, it is related to the twenty-four solar terms, and the odd number of the twenty-four solar terms is a festival; Even numbers are neutral. Under normal circumstances, a lunar month is full of festivals and spirits. However, because the number of days between two "neutral qi" is a little more than 30 days, and a new moon (a month in the lunar calendar) is only a little more than 29 days, the difference between them is nearly one day. Therefore, the gas in the lunar calendar will be delayed month by month, so it will be pushed to the end of one month, and there will be no gas in the next month, and it will not appear until the beginning of March. Therefore, the calendar will appear again.
