Is it a little hot in summer? Is summer heat the same as summer heat?

Introduction: When the dog days came, people began to spend the summer at home. There is a folk saying that "the cold is in Sanjiu, and the summer heat is in three volts". The so-called "three volts" refers to the first, middle and last three volts, and the summer volt that everyone says is another way of saying three volts. So is it a slight summer heat in summer? Is summer heat the same as summer heat? If you want to know, please take a look at my introduction.

Is the summer heat mild?

Summer heat is not a slight summer heat.

Summer refers to the dog days, that is, it is divided into three days: the beginning, the middle and the end, which is an integral stage. The summer heat is a few days before the summer heat, and the two cannot be equated. Summer is the eleventh of the twenty-four solar terms, at the end of the afternoon and the beginning of the month. The sun reaches longitude 105 degrees, and the festival is held on July 6-8 of the Gregorian calendar every year. Summer means hot, a little hot, not very hot. It's getting hotter, but not the hottest. Although light summer is not the hottest season in a year, it is followed by the hottest solar term in a year. There is a folk saying that "it is hot in summer and hot in summer, and it is steamed and cooked". Many places in China have entered the season with the most thunderstorms since summer.

The heat began to enter the dog days. The so-called "hot dog days". The dog days generally appear between the hot summer and the hot summer, which is the period with the highest temperature, the highest humidity and the sultry heat in a year. Monsoon climate is the main feature of China climate. In summer, affected by the warm and humid air flow from the ocean, many places in China are hot, humid and rainy. Although the sun is scorching, it is hot, humid and rainy at this time. For crops, the same period of rain and heat is conducive to growth.

Is summer heat the same as summer heat?

Summer heat and summer heat are not the same thing. Summer heat is one of the 24 solar terms. Just before summer heat, summer heat refers to the "dog days", that is, the period from the third "Geng Day" after summer heat to the end of 10 day after beginning of autumn.

"Fu" can be called "summer time", and "Fu" is the heterogeneous distribution of the five elements to the seasons, in which "Fu" is "earth". "Fu" means being forced by qi and blood and having to hide underground. Spring, summer, autumn and winter are crowned with wood, fire, gold and water by the five elements. Spring, summer, autumn and winter in five seasons of the year, from autumn to winter, gold produces water, fire produces soil, wood makes fire, and of course it is a circulatory system. But from summer to autumn, it is not. Neither Huo nor Jin dared to go out. You need to ambush for a period of time, and "ambush" is the original intention of "crouching".

The actual time of summer is determined by the coordination of holiday time and the time of working and supporting days. According to the traditional calculation method in China, the third and fourth Geng days after the slight summer heat are the starting time of lodging (head lodging) and lodging (second lodging) respectively, and the first Geng day after the cold dew is the first day before lodging.

Is it the first day of hot summer?

Slight heat is not the first day of heat.

The summer solar term precedes the summer solstice and is 15 days later than the summer solstice, but the summer solstice solar term is not necessarily. It may be 20 days after the summer solstice solar term or 30 days after the summer solstice, and there is no exact date. It usually comes in July and August of the solar calendar.

How to calculate the heat in summer

In the lunar calendar used in China, there is a "branch calendar", which uses 10 for "heavenly stems" (A, B, C, D, E, G, Xin, Ren, Gui) and "earthly branches" (Zi, Ugly, Yin, Mao, Chen, Si, Wu).

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.
