Solar terms around 3165438+August 1 1 3 BC or113 BC are also acceptable.

Solar terms are determined according to the position of the earth on the orbit of revolution, so the corresponding relationship between solar terms and dates is basically fixed in the solar calendar.

According to the current calendar, August 7th is beginning of autumn, August 23rd is midsummer, and August 1 1 and 13 do not correspond to a certain solar term.

Drunk green cow, your explanation is so confusing! I agree with the second paragraph (if I understand it correctly). But when I saw the third paragraph, I was fooled! Why "you need to use gossip to determine whether a month is big or not?" Where did you see it? The month is determined according to the movement of the moon. What does it have to do with gossip? And why "the rules of leap month are also very troublesome." , that is, buy a leap according to the 24 solar terms! When there is only one solar term, it will leap in that month. Furthermore, I think the statement that "the practice of artificially adding and subtracting leap months in history is not ruled out" is very unreliable! For the lunar calendar, months are unlikely to increase or decrease at will. And I've only heard that the new dynasty will change festivals, such as the "New Year's Day" date of the previous dynasty.
