The lunar calendar belongs to a kind of lunar calendar: its years are divided into flat years and leap years. An average year is twelve months; A leap year is thirteen months. A month is divided into a big month and a small month, with 30 days in the big month and 29 days in the small month, and its average calendar month is equal to the full moon. Which month is older and which month is younger in a year is determined by calculation.

The lunar calendar is based on the lunar calendar (China calendar), because the lunar calendar is based on the change of the moon phase, regardless of the movement of the earth around the sun, so the changes of the four seasons in the summer calendar have no fixed time and cannot reflect the changes of seasons; However, the calendar can reflect the tidal phenomenon and is a guide for guiding maritime activities in ancient times.

Unlike the fixed solar year of 365 days or 366 days, the solar year sometimes differs from the lunar year by one month. In order to coordinate the number of days between the first month of the lunar calendar and the tropic year, the "leap method" is adopted to adjust the total number of days between the lunar calendar and the tropic year.
