Extended data

The lunar calendar is a combination of yin and yang. As early as Shang Dynasty, the vernal equinox, summer solstice, autumn equinox and winter solstice had been included in the calendar. From the Spring and Autumn Period to the Pre-Qin Period, it has been improved into eight solar terms, and four solar terms have been added, namely, beginning of spring, vernal equinox, long summer, summer solstice, beginning of autumn, autumnal equinox, beginning of winter and winter solstice, which have been clearly listed in China calendar.

At the same time, the twenty-four solar terms appeared one after another and gradually began to improve, until the twenty-four solar terms of the lunar calendar were formally and completely written into the lunar calendar from taichu calendar in the Western Han Dynasty, and were divided into twelve solar terms and twelve qi in detail, which became an inseparable part of the lunar calendar.

Solar terms are an integral part of the lunar calendar and express the apparent movement of the sun. Through the 24 solar terms, the lunar calendar can accurately reflect the changes of the four seasons throughout the year, which is convenient for people's production and life and agricultural farming. The twenty-four solar terms of the lunar calendar are the rules of the calendar, which are calculated by astronomical algorithm through actual observation. The lunar calendar month basically corresponds to the twelve atmospheres in China, and the twelve solar terms can appear in the second half of last month and the first half of this month.

The twenty-four solar terms of the lunar calendar are developed on the basis of four seasons and eight festivals. The turn of the Yin and Zhou Dynasties has been divided into four seasons, and the Spring and Autumn Period has been divided into eight sections. By the end of the Warring States period, a complete system of 24 solar terms had been formed (the astronomical position had been determined). Twenty-four solar terms are the basis for the lunar calendar to determine the name of the month and set up a leap month, and are also the main basis for agricultural activities.

Solar terms are determined by the position of the sun and reflect the apparent motion of the sun. The twenty-four solar terms in taichu calendar, which was formulated in the early years of the Western Han Dynasty, played a very important role, and it was clearly stipulated that the month without neutral atmosphere was a leap month. Later, the calendar was transformed into three calendars by Liu Xin in the late Western Han Dynasty. After several improvements, the basic form remained unchanged.
