Is the first autumn 24 solar terms?

The initial lodging is not 24 solar terms, but 10 days before the dog days.

The first summer is closest to the summer solar term, and its date is determined by the solar term date and the dry branch date. The first summer means that the real summer is about to begin. The dog days are divided into early summer, middle summer and late summer. The first autumn is from the third Geng day to the day before the fourth Geng day. Because every Geng day is separated by 10 days, the initial lodging time is 10 days.
