The exact time of the ambush

On July 1 1 day, 2023, it was the ninth consecutive year since 20 15, and it lasted for 40 days in 20 14. The specific time is as follows:

Initial accommodation: July11~ July 20th (10 days).

Mid-range: July 21~ August 9 (20 days).

Terminal: August10 ~ August 19 (10 days).

Not only the number of dog days is not fixed every year, but also the start date of dog days is different. As the folk proverb says, "In the third year, people count from summer to day." However, the process of human going to heaven and the process of high temperature in summer in meteorology are not a set of standards. The dog days are determined according to the ancient "method of keeping records of cadres and party branches" in China.

Every summer to the future, the third Geng Day (referring to the day with the word "Geng" on the trunk and branches) is the beginning period, the fourth Geng Day is the middle period, and the first Geng Day after beginning of autumn is the end period, collectively referred to as the dog days. According to the solar calendar, it appears from mid-July to mid-August, and the time is "one size fits all" regardless of region.

In the meteorological sense, entering summer means that the average daily temperature rises above 22 degrees Celsius for five consecutive days as the beginning of summer. From a national perspective, eligible areas often gradually enter summer from south to north.

The hottest time:

There is an old saying: "A little summer is a little summer, and a big summer is a big summer." It can be said that the slight summer heat and the great summer heat are the two hottest solar terms in a year.

As the saying goes, "the heat is not hot, but hot in dog days", which means that the heat is not the hottest time in a year, but the hottest time in a year is the summer solar term in dog days.

There is an old saying: "There are three volts in summer, and the summer is in the middle." There are three volts in summer, which are the first, middle and last three volts, and the hottest time is in the middle. July 2023 1 1 entered the Mid-Autumn Festival, July 2 1 entered the Mid-Autumn Festival, and the great summer in 2023 was on July 23, so it can be said that the solar term of the great summer is in the Mid-Autumn Festival, so normally speaking, the solar term of the great summer is the one with the highest temperature in a year.
