Twenty-four solar terms were the timetable used to guide farming in ancient China.

The Origin of Twenty-four Solar Terms The Twenty-four Solar Terms is a supplementary calendar made by China to guide farming in ancient times. It is a tool to reflect the changes of weather, climate and phenology, and to master the farming season, which affects the food, clothing, housing and transportation of thousands of families. It is the crystallization of the long-term experience and wisdom of the ancient working people in China, and it is a precious scientific heritage created by Chinese ancestors in thousands of years' practice.

Because China's lunar calendar is a combination of yin and yang, which is based on the movement of the sun and the moon, it can't fully reflect the solar cycle. But China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is entirely based on the sun. Therefore, 24 solar terms reflecting the solar cycle alone are added to the calendar as the criteria for determining leap months.

Twenty-four solar terms originated in the Yellow River Basin. Since 2000, the main political centers in China have been concentrated in the Yellow River Basin, and the 24 solar terms have been established on the basis of climate and phenology in this area. Because China has a vast territory and changeable terrain, the 24 solar terms are only a reference for many regions.

As early as the Spring and Autumn Period and the Warring States Period, the sundial was measured by earth gauge in ancient China (that is, a pole was erected on the plane to measure the length of the shadow of the noon sun) to determine the four solar terms of midsummer, midsummer, midsummer and winter solstice. In a year, the shortest day of the shadow of returning to the earth at noon is the summer solstice, the longest day is the winter solstice, and the shadow with moderate length is the vernal equinox or autumnal equinox. The book Shangshu in the Spring and Autumn Period described the solar terms. There were only four solar terms in Shang dynasty, while there were eight solar terms in Zhou dynasty. The names of the twenty-four solar terms first appeared in Liu An's "Instructions of Huainan Tian Zi" in the Western Han Dynasty, and the concepts of Yin and Yang, four seasons, eight places, twelve degrees and twenty-four solar terms were also mentioned in the preface to Historical Records Taishi Gong. In BC 104, the calendar edited by Luo and Deng officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. It is also stipulated that the month without neutral gas is designated as the leap month of last month.

Each of the 24 solar terms is about half a month apart, and there are two solar terms every month for twelve months. Among the 24 solar terms, "festival" refers to a period of a year, which is a representation of a period of time; And "qi" refers to climate, which is an overview of weather changes. It is the name given by the ancients according to the unique climate or phenology phenomena and agricultural activities in each stage. Together, the two words gè refer to the weather changes at a certain stage of the year. 12 solar terms, including beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, heavy snow and slight cold; The second solar term of each month is "Zhongqi", that is, there are 12 solar terms such as rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, summer heat, summer heat, autumn equinox, first frost, light snow, winter solstice and great cold. "Solar term" and "neutral qi" appear alternately, each lasting 15 days. Now people have called "solar terms" and "neutral gas" as "solar terms", that is, 24 solar terms.

Twenty-four solar terms and the zodiac

The subtle relationship between the twenty-four solar terms in China and the twelve western constellations: Similar to the twenty-four solar terms, the ancient ecliptic was divided into 12 equal parts from the vernal equinox, so the start and end dates or the day before and after the twelve constellations in astrology must be neutral energy in the twenty-four solar terms.
