Entering volts means entering "three volts". There is a folk saying that "early autumn occurs in summer solstice", which is the basis for establishing early autumn. The almanac stipulates that "the summer solstice sunset is on the third Geng day", which means "counting down from the summer solstice" and then falling asleep on the third Geng day. The "Geng Day" here refers to the days prefixed with "Geng" in the ancient "Ganzhi Jiri Law".
There are five Geng days between the summer solstice and the beginning of autumn this year, which are June 26th (Geng Xuri), July 6th (Geng Shen Day), July 16 (Wu Geng Day), July 26th (Chen Geng Day) and August 5th (Geng Yin Day). So there are 20 days in midsummer this year, and the whole dog days are 40 days. This year, the time is longer.
