What does it mean to count volts?

Question 1: How to calculate a few volts? What is its origin? When did you start counting volts? As the saying goes, "it's cold in three or nine days, but hot in three days." On the first day of my first night, I began to enter the hottest period of the year. The "Ninth Five-Year Plan" is counted from the winter solstice, but for the "several volts", the start date of the first autumn is always changing every year, which is calculated according to the "trunk and branch calendar".

The ancient book Qunfangpu said: "This is not the end of summer." Because after the slight heat, the hottest dog days of the year are coming. The dog days are the hottest time of the year, with concentrated rain and sunset. Hanshu? The Notes on Suburb Sacrifice said: "Sleeping means that Yin Qi will get up, but he can't get up because of the setting sun. So, it is hidden, and it is because of the name. "

Question 2: What do you mean by a few days? Every summer from mid-July to mid-August at 5: 00, it is a unique "three volts" solar term in China. "crouching" means being forced to hide underground, which is the hottest time of the year. Starting from the summer, according to the arrangement of dry and branch days, the third Geng Day is the first month. The fourth Geng Day was in the middle, and the first Geng Day after beginning of autumn was the last.

Question 3: What do you mean by dog days? The dog days appear between the light summer heat and the heavy summer heat, and are the days with the highest temperature, humidity and sultry weather in a year. The so-called "dog days" refers to the "dog days" of the lunar calendar, which is the hottest period of the year.

Question 4: What do you mean by dog days? The dog days, which appear between Xiaoshu and beginning of autumn, are the days with the highest temperature, humidity and sultry weather in a year. V means latent. The "crouching" of "dog days" means "crouching evil". That is, the so-called "six evils" (referring to "wind, cold, heat, dampness, dryness and fire"). The so-called "dog days" refers to the "dog days" of the lunar calendar, which is the hottest period of the year.

Question 5: What do you mean by dog days? The solar term appears between Xiaoshu and beginning of autumn, which is the hottest period of the year.

Starting from summer, the third Geng Day is the first time according to the arrangement of dry and branch days. The fourth Geng Day is Fu Zhong Fu, and the first Geng Day in beginning of autumn is the first day of Fu Zhong Fu, which lasts for ten days.

Question 6: What do you mean by dog days? The dog days, which appear between Xiaoshu and beginning of autumn, are the days with the highest temperature, humidity and sultry weather in a year. V means latent. The "crouching" of "dog days" means "crouching evil". That is, the so-called "six evils" (referring to "wind, cold, heat, dampness, dryness and fire"). The so-called "dog days" refers to the "dog days" of the lunar calendar, which is the hottest period of the year.

Question 7: What does squatting mean? What is three volts? Entering a crouching state means entering the dog days. "On the summer solstice, the head of the three gengzi falls", which is the basis for establishing the first autumn. The first Geng day in 20 14 was June 28th, the second Geng day was July 8th, and the third Geng day was July18th. Therefore, 20 14 began to fall from July 18, and it fell in the middle of July 28 to August 16, and finally fell by 8.

"Three volts" refers to the first, middle and last three volts, which is about mid-July to mid-August. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights in a day. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day. During the "three volts" period, the ground absorbs almost more heat than it emits, and the weather is the hottest. After that, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature gradually decreased. Therefore, the hottest time of the year generally appears in the "three volts" summer solstice.

From summer to the third watch in the future, the first (10 day), the middle (10 or 20 days) and the last (after beginning of autumn 10 day) are the hottest days of the year.

Question 8: What do you mean by three volts? Three volts.

Three volts is the general term for the initial (first) volt, the middle (second) volt and the last (third) volt. The earliest record of Sanfu was found in 676 BC, the second year of Qin Degong in the Spring and Autumn Period.

The dog days are collectively called "dog days" or "dog days". According to China's traditional deductive algorithm, the third Geng day from summer to the future is the first, the fourth Geng day is the middle, and the first Geng day after beginning of autumn is the last. The interval between two Geng days is 10 days, and the first Geng day after beginning of autumn is the last Geng day, so there are 10 days and 20 days from the middle to the last Geng day.

This is the hottest period in summer in China, from mid-July to late August in the solar calendar.

Question 9: What does an ambush mean? What do you mean by dog days?

Question 10: What do you mean by dog days? The dog days are the hottest days of the year. "V" means being forced to hide underground. "Three volts" is the general name of the initial, middle and final volts, which appears from mid-July to mid-August in the solar calendar every year. According to the climate law of the lunar calendar in China, predecessors have long stipulated: "The third Geng day from long summer to the future is the beginning, the fourth Geng day is the middle (second), and the first Geng day after beginning of autumn is the end (third), and the voltage is ten days * * thirty days." In some years, the "mid-crouch" is 20 days, while * * * is 40 days.

According to the textual research of Shu Tong, the lunar calendar and the perpetual calendar, this year is the year of rooster in the solar calendar in 2005. "Three volts" is: July 15, and the tenth day of the Chinese lunar calendar is the first day (also called Fu Tou); July 25, the twentieth day of the lunar calendar, medium volt (two volts); /kloc-The last day of August (dog days) in 0/4 is the first day of July in the lunar calendar.

Generally speaking, every volt is ten days and every volt is thirty days. But this year's "year" is "medium volt" (two volts) for 20 days. Therefore, the "dog days" period is forty days. That is, from the tenth day of the first lunar month to the last day (the twentieth day of the seventh lunar month), it is exactly forty days before and after.

The "dog days" are determined according to the ancient "method of keeping records of the sun by the cadres and branches". 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. As the saying goes, "it's hot in dog days." According to the traditional calendar of our country, it is the hottest dog days in summer all year round. Three volts refers to three consecutive periods of initial, intermediate and final voltage. From summer to the future, the third Geng day is the first day of dive (today is the first day of dive this year), the fourth Geng day is the first day of dive, and the first Geng day after beginning of autumn is the last day of dive, each of which is 10 day, but in some years it is 20 days, such as this year. Generally speaking, in the "dog days", the average temperature is the highest in the "middle range". Of course, this calculation method of the ancients is not very scientific, and it is not necessarily closely combined with the meteorological reality of that year. The extreme maximum temperature in all parts of the year does not necessarily appear in the "middle volt" or even in the "three volts". But in any case, "dog days" is indeed a hot summer time, and everyone should pay attention to heatstroke prevention and cooling.
