Excuse me, is it summer or autumn?

1986. June 10th of the lunar calendar. Is it summer or autumn?

It is Xinyou day in the second month of Yiwei in the Bingyin year. The last month is summer, the fire is not very strong anymore, and the severe heat is on July 23. So it’s not autumn, it’s autumn after 7.23.

August 8th is the beginning of autumn!
