What is the solar terms table of the 24 solar terms?
Twenty-four solar terms refer to the special festivals in the trunk and branch calendars that express seasons, phenology, climate change and the establishment of "December architecture", reflecting the influence of the sun on the earth and being listed in the representative list of human intangible cultural heritage.
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 the great cold.
"Twenty-four solar terms" reflect the annual apparent motion of the sun, so the date of "Twenty-four solar terms" in the Gregorian calendar is relatively fixed, with a difference of 1-2 days. The earth revolves around the sun once every 365 days at 6: 09 and 10 second (exactly) and rotates once every 24 hours. Because the orbital plane of the earth's rotation is not the same as the equatorial plane, but maintains a certain inclination angle, the position of direct sunlight on the earth is different all year round.

Autumn dew, autumn frost, little snow in winter and cold in winter. The two festivals remain unchanged every month, with a maximum difference of one or two days. June 2 1 day in the first half of the year, and August 23 in the second half.
