The origin of the lunar calendar

Lunar calendar is a traditional calendar in China, and it is also called lunar calendar, Chinese calendar, summer calendar, Han calendar and Chinese calendar. However, the lunar calendar is not a simple lunar calendar, but a combination of yin and yang. It takes the change period of the moon phase, that is, the length of the moon is one month, and refers to the length of the tropical year of the sun. By setting 24 solar terms and leap months, the average calendar year adapts to the tropic year. According to the chronology, the first year was the reign of Xuanyuan Huangdi, the ancestor of China.

According to the data, China's calendars and calendar years adopt the three-in-one calendar of Yin and Yang. When did it first originate? Therefore, it is impossible to verify it for the time being. According to the unearthed ancient books in Oracle Bone Inscriptions and China, it is generally believed that the current calendar rule of the integration of Yin and Yang originated in the Yin and Shang Dynasties. From ancient times to the end of Qing Dynasty when the solar calendar was put into use, there were 102 calendars in the history of China, such as Xia calendar, Shang calendar (lunar calendar), Zhou calendar, Western Han taichu calendar calendar, Sui emperor calendar and Tang Dayan calendar.
