How to calculate the heat in summer
In the lunar calendar used in China, there is a kind of "branch calendar", which consists of 60 groups of words "Tiangan" 18 and "Dizhi" 12, arranged in the order of year, month, day and time, and used repeatedly.
According to the provisions of the Law on Ganzhi Day, the date of the dog days is from the solstice of summer to the third Geng Day, which is the first lodging, the fourth Geng Day to the fifth Geng Day is the middle lodging, and the first Geng Day to the second Geng Day after beginning of autumn is the last lodging. Every Geng day is 65,438+00 days apart, and the number of mid-festival days is not fixed. There are four Geng days from summer solstice to autumn, with 65,438+00 days in the middle, five Geng days and 20 days in the middle.
Because the "dry branch" calendar is rarely marked in the current calendar, it is generally impossible to see which day is "Geng Day", which requires people to inquire about the old imperial calendar. Therefore, the traditional method of calculating the dog days starts from the summer solstice, and according to the arrangement of the dry and branch days, the third Geng day is the first day. The fourth Geng Day was in the middle, and the first Geng Day after beginning of autumn was the last.
