Regarding the 20 10 solar term in beginning of autumn, why is the calendar and the mobile calendar not the same day? Pray for the great gods.

Let me tell you clearly: No.7 is beginning of autumn. We have a custom here that beginning of autumn eats watermelons. It was yesterday that the older generation should have some algorithms, which should be based on that old almanac. Gregorian calendar: at 23: 57 on August 7, this is defined according to the science of the earth's revolution. The above situation may be because it was not handled well at this time.

Hope to adopt
