When will the dog days of 2022 begin?
July 16, 2022 entered the dog days, which was Saturday, June 18th of the lunar calendar. There is an old saying that "the third Geng sets an ambush after the summer solstice", which means that the third Geng sets an ambush after the summer solstice. "Geng Day" means that the date of the main branch year contains "Geng". The summer solstice in 2022 is June 2 1 in 2022, the dry branch date is the fourth day of March, and the third Geng day is the fourth day of April, that is, July 16 in 2022, so this day is the beginning of the dog days in 2022.
The length of dog days mainly lies in the difference between middle and next days. Because the third Geng day (the first autumn) after the summer solstice solar terms occurs at different times every year, the number of days of the Mid-Autumn Festival is also different. The incubation time is long or short, which may be 10 day or 20 days. So there are two situations: some years are 30 days in dog days, and some years are 40 days.
Dog days calculation time
Dog days, one volt is ten days, counted by days. Therefore, the dog days are divided into three days, that is to say, after the third day of Gengtian, the summer solstice is the first day, the first volt.
For example, the summer solstice in 2006 is June 2 1 in the western calendar year, and the dry day of this day is Xinri. 28 days later, it is the third Geng Day. Therefore, July 20, 2006 is the beginning of the first volt. Ten days later, it was another Geng day, that is, on July 30, it entered the second volt; Ten days later, it was another Geng Day, the first Geng Day after beginning of autumn, that is, August 9, and it entered the dog days.
