Extended data:
The lunar leap month is to coordinate the contradiction between the tropic year and the lunar year. 12 lunar months constitute lunar years, with a length of 29.5306× 12=354.3546 days, which is 10.88 days less than the regression and about 1/kloc-0 less than the monthly 0.9 1 day.
Accordingly, if the Spring Festival in one year of the lunar calendar is a snowy winter, the Spring Festival in the next year will be 1 1 day earlier than the season, and 16 Lunar New Year will appear in the hot summer.
If the lunar year consists of thirteen lunar months, the length is 29.5306× 13=383.8978 days, which is more than the tropic year 18 days.
If the calendar is made according to the above regulations, there will be a strange phenomenon that the weather is inconsistent with the calendar and the time order is disordered and reversed-this is contradiction.
