Lunar calendar is a lunar calendar, also called lunar calendar, which is based on the law that the moon revolves around the earth. Take the moon's orbit around the earth as a month, that is, take the new moon as the basis for determining the calendar month. A month in the lunar calendar is called a "new moon". The first day of each month is a new moon, and the fifteenth day is a new moon. The "new moon" is the average period of the moon's profit and loss. The lunar calendar only looks at the moon, regardless of the tropic of cancer, so it has nothing to do with the four seasons.

Compared with the solar calendar, the time of the lunar calendar is about eleven days apart every year. There is a great invention in China's calendar called "Setting Leap Method". Every 19 year has 7 leap months, and a year with leap months has 383 or 384 days, which is called leap year. For example, 20 16 and 2020 are leap years.
