Twenty-four solar terms refer to 24 specific festivals in the China lunar calendar, which indicate the changes of seasons. They are formulated according to the position change of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each one corresponds to a certain position reached by the earth every time it moves 15 on the ecliptic.
Twenty-four solar terms, a supplementary calendar established in the pre-Qin period and completely established in the Han Dynasty, is a knowledge system formed by observing the movement of the sun in a year and understanding the changing laws of the four seasons, climate and phenology in a year.
It divides the sun's annual trajectory into 24 equal parts, and each equal part is a solar term, starting from beginning of spring and ending with severe cold. It is not only a time standard promulgated by successive governments, but also a compass to guide agricultural production. People's compass for predicting cold, warm, rainy and snowy weather in daily life is the crystallization of the long-term experience and wisdom of Chinese working people.
