Are the 24 solar terms a supplementary calendar used to guide farming in ancient China?

Solar terms refer to the twenty-four solar terms and climate, which is a supplementary calendar formulated by China in ancient times to guide farming, and is the crystallization of the long-term experience and wisdom of the working people of the Han nationality.

In ancient times, heaven and man were one. The first duty of any leader is to look up and down, teach the people the calendar, and take sacrifice and management etiquette as the center; The second is to expand the territory. Only when you have the ability to "understand astronomy and teach human crops" can you get the respect and support of your ancestors and become a "leader". History shows that the Neolithic Age of primitive society is the embryonic state of the development of astronomy in China. At that time, people noticed the rise and fall of the sun and the change of the moon's profit and loss, which produced the concepts of time and direction. In the era of Suiren, the north pole of the celestial sphere was determined, and the river map, Luo Shu and ephemeris were created. In the Fu era, the Eight Diagrams were invented and the astronomical observation system was established. When Emperor Yan arrived, he invented the solar calendar, discovered sunspots and invented the Mars calendar, which promoted the continuous progress and development of human civilization.

There are records of "day", "day", "night", "day" and "short" in Shangshu Yaodian, which are equivalent to the four solar terms of vernal equinox, summer solstice, autumn equinox and winter solstice. In Zhou Li, there are "winter and summer arrive at the sun, and spring and autumn arrive at the moon to distinguish the four seasons", "winter solstice, playing on the ground dome" ... summer solstice, playing on Zezhongguang Mountain, which clearly puts forward the winter solstice and summer solstice. At the end of the Warring States Period, Lu Chunqiu included the names of equinox (vernal equinox, autumnal equinox), summer, winter, beginning of spring, Changxia, beginning of autumn, beginning of winter, Liyu, long summer and Lishuang. During the Western Han Dynasty, the 24 solar terms were completely established.
