Hello, Doushu family at your service. The ancient yellow calendar or perpetual calendar was printed according to the lunar calendar. There was no Gregorian calendar in ancient times. The lunar calendar, also known as the lunar calendar, sets the month according to Wang Shuo's cycle. By placing a leap, the average length of a year is close to the tropic of cancer of the sun. There are also some names, such as summer calendar and Han calendar. Lunar calendar is a calendar used in parallel with Gregorian calendar in China at present. Although people are used to calling it the "lunar calendar", it is actually a kind of lunar calendar, and it is not just a lunar calendar based on the moon phase cycle.

The standard name of Gregorian calendar is Gregorian calendar, which is an international calendar and a solar calendar. The solar calendar is the abbreviation of the solar calendar, which is related to the earth's annual orbit around the sun, and has nothing to do with the moon phase. Gregorian calendar is a western calendar, not created by China, so it is also called "western calendar" (relative to China calendar).

After the Revolution of 1911, China adopted the Gregorian calendar from the first year of the Republic of China, so it is also called the "national calendar". It is also called the "new calendar" because it is symmetrical with the old calendar in China. 1949 officially stipulates the ADoption of ad calendar.
