Is the lunar calendar in China?

Strictly speaking, the lunar calendar in our country should not be called lunar calendar, but "yin and yang combined calendar"

Lunar calendar is a combination of yin and yang widely used in East Asian folk traditions. According to ancient legends, it was founded in the era of the Yellow Emperor or the Xia Dynasty, also known as the Yellow Calendar and the Summer Calendar. After the founding of the Republic of China, Sun Yat-sen announced the adoption of the western Gregorian calendar, while the traditional calendars in China were called the old calendar and the traditional calendar. After the establishment of People's Republic of China (PRC) (China), the Gregorian calendar was adopted as the Gregorian calendar, and the old calendar was renamed as the Lunar calendar.

The lunar calendar is a lunar calendar: "Yang" is based on the year from winter to day to determine the age, and is divided into 24 solar terms according to the solar season and the sun; Yin determines the moon according to its movement. The current lunar calendar version is based on the established basic rules, revised by using the achievements of modern astronomy, and calculated completely according to astronomical data.

The lunar calendar, like the western calendar and the Islamic calendar, is one of the calendars widely used now. In China, many ethnic minority areas, North Korea, South Korea, Viet Nam and overseas Chinese communities around the world, the lunar calendar is widely used as a birthday symbol and various folk festivals, such as the New Year, Lantern Festival, Dragon Boat Festival, Mid-Autumn Festival and Double Ninth Festival, and is regarded as a symbol of China culture.

A calendar is a coordinate system for recording time. Most ancient peoples determined their calendars according to astronomical phenomena, and they all had the concepts of year and month: year is the cycle of four seasons, that is, the earth revolves around the sun; The moon is the profit and loss cycle of the moon phase, that is, the moon revolves around the earth. Accurately measuring the length of the tropic year and the lunar month, we will find that a year is about more than twelve months 10.875 days, that is, a single lunar calendar or solar calendar cannot meet the exact period of the year and the month at the same time.

Calendars can be divided into three types: solar calendar, lunar calendar and yin-yang calendar:

1, solar calendar (solar calendar):

The annual apparent movement period of the sun is one year, divided into 12 months, which has nothing to do with the movement of the moon. According to the date of the solar calendar, we can know the changes of the four seasons from cold to summer, and guide agriculture reasonably. Gregorian calendar is a kind of solar calendar.

2. Lunar calendar (lunar calendar):

China lunar calendar does not belong to this category, but people are used to calling it the lunar calendar in their lives. Take the period of the moon as one month, and the product of 12 months is one year. It completely ignores the annual apparent motion law of the sun, so the date of the lunar calendar can't show the warmth and coldness of the four seasons. This calendar has no practical value, except for Islam, it has been abandoned.

3. Lunar calendar:

The lunar calendar in China belongs to this category, with the cycle of the moon phase as the month length and the year of the return of the sun as the age. By setting leap months, the average calendar year is adapted to the tropical year. According to the date of the lunar calendar, we can not only know the ebb and flow of tides, but also grasp the changes of seasons.
