Extended data:

"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.
