The ancients called the day when the moon was completely invisible "Shuori" and the day when the moon was the most round "Looking at the sun". The new moon is the first day of each month, and the new moon is the fifteenth day of each month. From solar eclipse to lunar eclipse, it is divided into one month, which is called "eclipse month" in legislation. The exact time is 29 days 12 hours, 44 minutes and 3 seconds, about 29 days and a half.

The lunar calendar defines 12 months as one year, which adds up to a little more than 354 days. Because the moon is easy to observe, its cycle is about 30 days, unlike the 365-day cycle of the sun, so early human civilization used the lunar calendar most of the time.
