Basic introduction

The dog days appear between the slight summer heat and the severe summer heat (from mid-July to mid-August in Gregorian calendar), and the dog days are divided into three days: the beginning, the middle and the end. Dog days are characterized by high temperature, low air pressure, high humidity and low wind speed. "Fu" means being forced to hide underground, and the date of three volts is determined by the date of solar terms in the dry calendar and the date of the dry calendar.

Because every Geng day is 10 days apart, the stipulated time of the first day and the last day is 10 days. Because the third Geng day (the first autumn) after the summer solstice solar terms appears sooner or later, the days in autumn are long and short.
