Did it feel good after the last lie?

The last drop does not mean that the weather will cool down immediately.

The last dog day is the last dog day, which generally lasts about 10 days. Although the weather is still hot at this time, it will be too hot next month, and it will gradually cool after the autumn tiger passes. So the last drop doesn't mean the weather will turn cold immediately.

The last stage is not the hottest yet. The hottest of the three volts is the middle volt, which is two volts. This is because the humidity of the surface becomes higher after the fall, and the surface absorbs more heat every day, but emits less heat, and the surface heat accumulates, so it is getting hotter every day. Therefore, the last volt is not the hottest time in dog days.

The so-called "crouching" means "summer heat lurks underground", which marks the hottest period of the year; Some explanations are that "squatting" means it is too hot to move. The dog days appear between the hot summer and the hot summer, and its climate is characterized by high temperature, low pressure, high humidity and low wind speed.

Date calculation in dog days

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. The dry day of this day is Xin Day, and 28 days later 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; If it is 2007, July 15 is the third Geng day and the beginning of the first volt.

Ten days later, it was another Geng day, that is, July 25, and it entered the second volt (middle volt); Ten days later, it's another watch day, but I haven't been to beginning of autumn yet. Ten days later (there are still 20 days in mid-autumn this year), it will be another Geng Day, the first Geng Day after beginning of autumn, that is, in August of 14, it will enter the dog days.

In other words, every year after the dog days, it is very hot, especially in the middle ten days (sometimes twenty days), which is the hottest. There is a folk saying that "the cold is in the March 9th and the summer heat is in the middle".
