When will the dog days end?

The dog days, which appear between the summer heat and the summer heat, are the period with the highest temperature, the highest humidity and the most severe sultry heat in a year. Dog days are usually divided into 30 days and 40 days. The dog days are divided into three volts, namely, one volt (first volt), two volts (middle volt) and three volts (last volt).

The first and last ambushes in dog days are fixed, each ambush lasts 10 days, and the middle ambush can be divided into 10 days and 20 days. After "entering the volt", many places in the country will enter the continuous high temperature mode. The dog days in 2023 start from July 1 1, and the last day to the last day is August 19, and the last day ends on August 20th, so the dog days in 2023 are over, with 40 days.

How to determine the specific date of dog days;

The date of the dog days is determined according to the "Ganzhi Day" in ancient China. Every year, the third "Geng" day from summer is the beginning period, the fourth "Geng" day is the middle period, and the first "Geng" day from autumn is the end period, which are collectively called "dog days". "Geng" is the word "Geng" in Ten Days' Work. The interval between ridges is 10 day, and the time of the first arrival is fixed at 10 day.

The time from the middle period of lodging to the end of lodging is not fixed, because the date of lodging is the first Geng Day after beginning of autumn. When there are four Geng days before beginning of autumn, the time interval from the middle lodging stage to the end lodging stage is 10 day. In the first five shifts of beginning of autumn solstice, the time interval from the middle lodging stage to the end lodging stage is 20 days.
