What does Three Summers and Nine Volts mean?

What does the three summers and nine volts mean? The three summers and nine volts refer to the first, middle and last days of summer, also known as the long summer.

The first period is from mid-July to mid-August, which is the hottest time of the year.

Zhongfu counts to the third Geng day after the summer solstice, approximately from late July to late August.

Mofu is the last few days after the summer solstice, and the specific time varies depending on the year.

During the period of three summers and nine volts, Yang Qi is strong. In order to adapt to the weather, the human body is in a situation where "Yang is strong outside and deficient inside", it will sweat a lot, resulting in the summer physical characteristics of deficient Yang Qi.

At this time, the temperature is the highest and it is humid and sultry, so you need to prevent heat and humidity.

Expansion: The dog days of summer. The dog days of summer occur between the mild summer heat and the extreme summer heat. They are the hottest, humid, and sultry period of the year.

The Three Volts can be divided into the first, middle and last periods, and their dates are determined by the combination of the twenty-four solar terms and the dates of the stems and branches.

After the "fall", many places across the country will enter a sustained high temperature mode.

The traditional almanac stipulates: "On the third Geng day of the summer solstice, the number of volts begins." This means that counting from the summer solstice onwards, the number of volts begins on the third Geng day.

The "Geng Day" here refers to the day with the prefix "Geng" in the ancient "Stem and Branch Day Calendar".

"Fu" means that Yin Qi is forced by Yang Qi to hide underground; it also means that the weather is too hot and it is better to stay down than to move.

The length of Futian mainly lies in the difference between Zhongfu.

Because the third Geng day (first fall) after the summer solstice occurs at different times every year, the number of days leading to the middle fall is also different.

The duration of the incubation period may be long or short, it may be 10 days or 20 days.

So there are two situations: some years have 30 days of dog days, and some years have 40 days.

"Three volts" and "three summers" (the minor summer heat, the severe summer heat, and the extreme summer heat in the twenty-four solar terms) both represent extreme high-temperature weather. The curves on the time axis and the temperature axis are basically the same: when the summer days come, the dog days arrive; when the dog days disappear, the summer days will come.

All.

The reason why the ancients called the extremely hot days of the year "summer" and also found the word "volt" to accompany it is that in addition to the cultural meaning, another important purpose is for health preservation.
