How many days are there in the Dog Days of 2022? When will the ambush occur? When will you go out? Timetable is coming

Everyone has heard the old saying "It's cold at 39 and hot at 3 volts". Dog days are the hottest time of the year. Since the time of volts is not fixed every year, plus the mid-volt days, The length also varies, causing the Dog Days to fall at different times each year.

Many friends are more concerned about the time of entering and exiting the ambush, so this article will talk about the relevant content of the dog days of this year (2022) in detail, such as when will the ambush enter the ambush? When will you go out? How many days in total? Everyone will have the answer after reading it.

First of all, let's understand when the ambush began. According to the ancient calendar, "Summer Solstice Sangeng" is used to express the time of the ambush, which is the third "summer solstice" after the solar term. Geng" day.

How to understand "geng"? It belongs to the ancient "stem and branch date counting method". It is different from the current calendar. In the past, 60 different sets of names composed of 10 heavenly stems and 12 earthly branches were used to record the days and were used repeatedly.

The 10 heavenly stems are "A, B, B, Ding, Wu, Ji, Geng, Xin, Ren, and Gui", and the twelve earthly branches are "Zi, Chou, Yin, Mao, Chen, Si, "The general name of "Wu, Wei, Shen, You, Xu and Hai", if they match, the day with the word "Geng" is the Geng day, and the Geng day can be repeated every 10 days.

After understanding this, starting from the summer solstice, the third Geng day is the time to enter the ambush.

The summer solstice in 2022 is June 21st, which is the day of Bingwu month and Yisi day. The third Geng day will be on July 16th.

Therefore, it can be concluded that the time of entering the ambush this year is July 16, 2022.

Let’s look at another question. The length of time of Zhongfu is different. In some years, it is 10 days, and in other years, it is 20 days. How to judge? As mentioned above, every Geng day is repeated every 10 days, and the 10 days of the first Geng day are fixed. That is to say, the fourth Geng day begins to enter the middle Fu day, and the time of the last Geng day is based on the first Geng day after the beginning of autumn. Calculated in days, the time of the last period is also fixed, and the number of days is 10.

So, if you check how many Geng Days there are between the Summer Solstice and the Beginning of Autumn, you can determine the number of days of Zhongfu. If there are 4 Geng Days, then the number of days of Zhongfu is 10 (Chapter 10) It takes 3 Geng days to enter the first Fu). If it contains 5 Geng days, then the number of days in the middle Fu is 20 days.

Looking up the 2022 calendar, we found that there are 5 "geng days" between the summer solstice and the beginning of autumn. Therefore, the number of mid-summer days this year is 20.

Seeing this, the time for the dog days of 2022 is very clear.

Toufu: July 16, 2022-July 25, 2022, ***10 days;

Mid-fu: July 26, 2022-August 2022 14th, ***20 days;

Mofu: August 15, 2022 - August 24, 2022, ***10 days.

The Dog Days of 2022 will start on July 16, 2022 and end on August 24, 2022. It lasts for 40 days. It is another long Dog Days. If you are interested in the Dog Days, , you may have the feeling that in recent years, the dog days of summer have always been 40 days, and rarely 30 days.

This is indeed the case. Looking at the calendar, starting from 2015 and going on to 2024, in these 10 years, the duration of Dog Days has been 40 days. By 2025, the duration of Dog Days will be 40 days. Time will appear again in 30 days. This is also the reason why many friends feel that the summer heat has been relatively long in recent years.

Seeing this, I would like to add one more point about the weather on the day of the head-turning.

Some people say rain is good, others say sunny days are good.

If according to folk saying, if it rains on the day of dog days, there may be a "leakage" phenomenon on the dog days of that year, that is, from the perspective of rainy days, and even waterlogging may occur, both from the perspective of daily life and agricultural planting. Generally speaking, the results are not very good.

If it is sunny on the day of Dog Day, according to the saying "It is sunny at the beginning of Dog Day, and there is drought and heat everywhere." From the beginning of Dog Day, it will be relatively dry all the way to the summer solar terms, that is, including the entire Dog Day. , indicating that there is less rainfall and the temperature is already high in the dog days of summer. When drought occurs in the fields, the growth of crops is inhibited, which is also unfavorable.

Since both sunny and rainy days are not good, this illustrates a problem. Whether the weather is sunny or rainy on the day of the ambush has nothing to do with the quality of subsequent weather. Sunny or rainy days do not matter. Follow-up still depends on the local weather forecast.

Based on the above, 2022 is still the "extended version" of the dog days of summer, from July 16 to August 24, 40 days in one month. In the hot weather, everyone should take more Pay attention to heatstroke prevention, and at the same time, do a good job of irrigating crops.
