Eating hot pot in dog days is a good way to build a clean government.

The dog days are days between light summer and hot summer, with the highest temperature in a year, humid and sultry, from the middle and late July to the middle and late August in the solar calendar.

"V" means being forced to hide underground. There are three kinds of fu: initial fu, middle fu and final fu, and their dates are determined by the solar terms and dates of the dry branch calendar. After "entering the volt", many places in the country will enter the continuous high temperature mode.

In 2022, the accommodation time will be July 16, and the "three days" will last for 40 days. The initial accommodation will be from July 16 to July 25th, the intermediate accommodation will be from July 26th to August 14, and the final accommodation will be from August 15 to August 24th.

Incubation time:

The time of accommodation is not fixed every year, and the length of accommodation is also different. You need to check the almanac to calculate it. Simply put, we can use the formula of "Xia San Geng" to express the lodging date, that is, from the third Geng day in Xia Hou, the initial lodging is 10 day, the intermediate lodging is 10 day or 20 days, and the final lodging is 10 day.

In ancient China, the method of "recording the date by branches" was popular, and 60 groups of different names matched with 10 heavenly stems and 12 earthly branches were used to record the date for recycling.

The day with the word "Geng" is called "Geng Day". The word "Geng" in Geng Day is the seventh word in "A, B, C, D, E, Ji, G, Xin, Ren, Gui" 10 day, and it is repeated every 10 day.

Starting from the summer solstice, according to the date of trunk, the third Geng day is the first, the fourth Geng day is the middle, and the 1 th Geng day after beginning of autumn is the last. When there are four Geng days between the summer solstice and the beginning of autumn, the middle part is 10 days, and when there are five Geng days, the middle part is 20 days.
