Summer Fu, also known as "Sanfu", is the expression of the hottest period of the year in the old calendar of our country. It is divided into the first volt (the first volt), the middle volt (the second volt) and the last volt (summer volt).

According to the climate law of China's lunar calendar (lunar calendar), the predecessors have already stipulated: "The third Geng day after the summer solstice begins to be the first volt (the first volt), the fourth Geng day is the middle volt (two volts), and the first Geng day after the beginning of autumn is the end of the volt (summer volt), the first volt and the last volt are ten days each, and the middle volt is ten days or twenty days, and the "summer volt" is a total of 30 or 40 days.

Every year, if there is a Geng day on the beginning of autumn and the next two days, it is ten days in the middle of the volt, otherwise it is twenty days, so in most years, the middle volt is twenty days, and correspondingly, in most years, the summer volt is forty days.

"Three dog days" is the expression form of the hottest period of the year in the old calendar of our country. It is divided into the first volt (head volt), the middle volt (two volts) and the last volt (three volts). According to the ancient calendar of our country, it is now determined:

The first day of the first day is the third Geng day after the summer solstice; The first day of the middle volt is the fourth Geng day after the summer solstice; The first day of the end is the first Geng day after the beginning of autumn. 2014-06-21 [Summer Solstice] Guihai Day.

On July 16, 2021, the summer season began, and the dog days lasted for 40 days.

The so-called three dog days are the general term for the beginning, middle and end volts. The date of the dog days is determined by the date of the solar term and the date of the stem branch. According to the provisions of the lunar calendar, the interval between two adjacent Geng days is ten days, so the time from the first to the middle is fixed at ten days.

However, due to the stipulation that the first Geng day after the beginning of autumn is the last day, there are two situations: ten days and twenty days from the middle to the end of the year. The last and last days, like the first one, are fixed at ten days.

Dog days are the hottest, humid, and muggy times of the year.

The time of "ambush" is calculated according to the date of the solar term and the date of the Ganzhi period, and it should be calculated from the beginning of the "Geng day". The temperature is the highest, and the incubation time needs to be twenty days after the summer solstice, and the traditional algorithm "dog days" starts from the third "Geng day" after the summer solstice and ends on the second Geng day after the beginning of autumn.

The climate of dog days is characterized by "high temperature, high humidity, high heat", because dog days blow southeast wind, the air is humid, and the humidity of the wind causes high humidity during the dog days of the summer to the summer, and this kind of weather appears in the southern region of our country.

There are 40 dog days in 2020, and they began on July 16, 2020, and ended on August 24, 2020, for a total of 40 days.

The details are as follows: dog days: July 16 to July 25 in the solar calendar, a total of 10 days, dog days: July 26 to August 14 in the solar calendar, a total of 20 days, dog days:

From August 15th to August 24th in the solar calendar, a total of 10 days, so the dog days in 2020 last for 40 days, during which farmers must pay attention to the growth of crops to avoid losses due to high temperatures.

Now it's mid-volt.

Dog days thirty.
