Introduction.

According to the traditional calendar, "summer to sunset is on the third Geng day", which means that the countdown starts from summer to Sunday and is set on the third Geng day. The "Geng Day" here refers to the days prefixed with "Geng" in the ancient "Ganzhi Jiri Law". "Fu" means that Yin Qi was forced by Yang Qi to hide underground; This also means that it is too hot to move.

The length of midsummer is mainly due to the difference between midsummer and midsummer. Because the time of the third Geng day (the first autumn) after the summer solstice solar term is different every year, the number of days in the first autumn is also different. Summer is long and short, which may be 10 days or 20 days. So there are two situations: some years are 30 days and some years are 40 days.
