The origin of the twenty-four solar terms:

Originated in the Yellow River Basin, it is the crystallization of long-term experience and wisdom of working people in ancient China. As far back as the Spring and Autumn Period, solar terms such as mid-spring, mid-summer, mid-autumn and mid-winter were set. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. In BC 104, taichu calendar, written by Deng Ping, officially set the 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. ?

As early as the Spring and Autumn Period and the Warring States Period, China used Tugui to measure the sundial in ancient times (that is, to measure the length of the sun's shadow at noon by erecting a pole on the plane) to determine the four solar terms of vernal equinox, summer solstice, autumnal equinox and winter solstice. In a year, the shortest day of Tugui's shadow at noon is the summer solstice, and the longest day is the winter solstice, and the moderate shadow length is the vernal equinox or autumnal equinox.

In the spring and autumn period, the book Shangshu recorded the solar terms. In Shang Dynasty, there were only four solar terms, but in Zhou Dynasty, there were eight solar terms. The names of the twenty-four solar terms first appeared in Liu An's Huai Nan Zi Tian Xun 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 of Historical Records Taishigong.

In ancient China, the lunar calendar was used to record time, and the solar calendar was used to divide the 24 solar terms of spring, summer, autumn and winter. Our ancestors called five days 1 weather, and three days were regarded as one, which was called solar terms. The whole year was divided into 72 days in 24 solar terms.

The time that the sun travels 15 degrees along the yellow meridian from zero degree is called "a solar term". It runs 360 degrees every year, and * * * experiences 24 solar terms, 2 times a month. Among them, the first solar term of each month is "solar term".

Namely: beginning of spring, Jingzhe, Qingming, long summer, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Heavy Snow and Slight Cold 12 solar terms; The second solar term of each month is "Zhongqi", that is, 12 solar terms such as rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, great summer heat, summer heat, autumn equinox, first frost, light snow, winter solstice and great cold.

"Solar terms" and "neutral gas" appear alternately, each lasting 15 days. So far, people have collectively referred to "solar terms" and "neutral gas" as "solar terms".

In BC 104, taichu calendar, written by Deng Ping, officially set the twenty-four solar terms in the calendar, and defined the astronomical position of the twenty-four solar terms.
