Why are the 24 solar terms * * * a total of 360 days, 365 days a year? As time goes on, solar terms and days in the solar calendar are roughly balanced. I didn't say anything.

Let me answer you. Let me define it first. The twenty-four solar terms are divided according to the position of the sun on the ecliptic (that is, the orbit of the earth around the sun). So strictly speaking, the interval between solar terms should be 15.2 days. But people's general definition of the sky is day and night, so the interval between the 24 solar terms is usually 15 days, but sometimes 16 days. Count it on the calendar!
