China traditional calendar 24 solar terms belong to what calendar?

Twenty-four solar terms are the traditional calendar of China, which belongs to the Yin and Yang calendar.

The mixed calendar of yin and yang, as its name implies, is a mixed calendar that takes into account the revolution of the earth and the moon. The lunar calendar is a typical lunar calendar.

Lunisolar calendar refers to a calendar in astronomy that takes into account the relationship between the sun, the moon and the earth. In the lunar calendar, the moon orbits the earth 1 month, but the leap month is set to make the average number of days in a year consistent with the number of days in the tropic of cancer, so this calendar is consistent with the periodic movement of the moon and the earth around the sun. The summer calendar is a kind of lunar calendar, and the specific calendar also includes the method of chronology (era). The traditional calendars of Japan, Korea and Middle East Israel are also lunar calendars, which are also used by other ethnic groups such as Tibetans and Dai people.

The solar year is fixed at 365 or 366 days. The difference is that the number of days in different lunar years sometimes differs by one month. In order to coordinate the days of the solar calendar and the lunar calendar, the yin-yang calendar, which is now the lunar calendar, was produced. The method adopted is "65438+7 leap years in 2009", that is, seven leap years are added to the 19 lunar calendar. Because there is a leap month in the lunar leap year, there are 383-385 days in a year, while the general lunar year usually has 353-355 days.
