24 There are no dog days in the solar terms, so what are the dog days in summer?

"Dog days" are the three consecutive periods of the hottest summer in the old calendar of our country. "Dog days"It refers to the beginning, middle and last volts, which is about the period from mid-July to mid-August. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are still longer than the nights, and the ground still absorbs more heat than it emits every day, and the temperature near the ground is getting higher day by day.

to"Dog days"During this period, the ground absorbs almost less heat than it emits, and the weather is at its hottest. After that, the ground begins to absorb less heat than the ground emits and the temperature slowly drops. So the hottest time of the year generally occurs on the summer solstice"Dog days"。

Counting from the third "Geng" day after the summer solstice, the first volt (10 days), the middle volt (10 20 days), and the last volcanic (counting from the first Geng day after the beginning of autumn, 10 days), is the hottest time of the year.

Dog days are between the summer solstice and the beginning of autumn.

Usually from the third Geng day after the summer solstice, until the end of the first Geng day after the beginning of autumn, because the time of the Geng day is not the same, so the time of the dog days is not the same every year, and the length of time will be different, some years have 30 dog days, and some years have 40 dog days, and 2020 dog days have 40 days, of which there are 20 days in the middle of the dog days, and the duration will be longer.

According to the solar terms, dog days generally experience the summer solstice, the summer heat, the great heat, and the beginning of autumn, and if the dog days are relatively long, there are 40 days, it is likely to transition to the summer solar terms. For example, the specific time of this year's dog days is July 16, 2020 - August 24, 2020, and the specific time of this year's summer solar term is August 22, 2020, which also shows that this year's dog days will end after the summer season, and the whole time is relatively long.

Dog days are generally between the summer solstice and the beginning of autumn.

Sanfu is a general term for the beginning, middle and end. Dog days occur between the summer and the summer, and are the hottest and humid and muggy times of the year.

The "volt" in the three dog days has two meanings. First, it means that the yin energy is forced by the yang energy to hide underground; Second, it means that the weather is too hot, and it is not suitable to move.

The time of incubation is determined by the date of the solar term and the date of the dry branch. The climate of dog days is characterized by high temperatures, low air pressure, high humidity, and low wind speeds.

China's traditional estimation method stipulates that the third Geng day after the summer solstice is the beginning of the "first volt", the fourth Geng day is the beginning of the "middle volley", and the first Geng day after the beginning of autumn is the beginning of the "last volt".

Because there are 10 days between each Geng day, the prescribed time for the first and last days is 10 days. The number of days in the middle of the volt can be long or short, it may be 10 days or 20 days, depending on the date of the occurrence of the third Geng day (the first volt) after the summer solstice solar term each year.

What are the two solar terms between the Spring Festival?

The Spring Festival is generally in the beginning of the spring solar term in the 24 solar terms. The beginning of spring is the first of the 24 solar terms, also known as the beginning of the Spring Festival, the New Year's Festival, the New Year's Festival, the New Year's Day, etc.

"Dog days" are the hottest days of the year. "Fu" means that the yin energy is forced by the yang energy to hide underground. "Three dogs" is a collective term for the beginning, middle and end of the volt, which occurs every year from mid-July to mid-August in the solar calendar.

According to the climate law of China's lunar calendar (lunar calendar), the predecessors have long stipulated: "The third Geng day after the summer solstice begins to be the first volt (first volt), the fourth Geng day is the middle volt (two volts), and the first Geng day after the beginning of autumn is the last volt (three volts), and every ten days is a total of 30 days." In some years, there are 20 days in the middle of the year, and there are 40 days in total.

According to the "General Book", "Lunisolar Calendar" and "Perpetual Calendar", it can be seen that this year is the year 2005 of the solar calendar, and the year of the lunar calendar. The "dog days" are:

On July 15, the first ten Gengzi day of the lunar calendar is the first volt (also called the first volt); On July 25, the 20th day of the lunar calendar is the middle volt (two volts); On August 14, the tenth day of the seventh month of the lunar calendar, Gengwu is the last day (three dogs).

In a normal year, every 10 days, a total of 30 days. But this year's "year" is 20 days of "mid-volts" (2 volts). Thus, the "dog days" period is forty days.

That is, from the beginning of the tenth day of the lunar calendar to the last day of the end of the lunar calendar (the 20th day of the seventh month of the lunar calendar), exactly 40 days before and after.

The "dog days" are determined in accordance with the ancient "Ganzhi Chronicle Law" in China. Every year after the summer solstice, the third Geng day (referring to the day with the word "Geng" in the Ganzhi Chronicle) is the first volt, the fourth Geng day is the middle volt, and the first Geng day after the beginning of autumn is the last volt, which together is called the three volts. As the saying goes, "the heat is in the dog days", according to the traditional calendar of our country, today begins to enter the summer is the hottest "dog days".

The dog days refer to the three consecutive periods of the beginning, the middle and the end. The third Geng day after the summer solstice is the first day of the first volcanic period (today is the first day of the first volt of this year), the fourth Geng day is the first day of the middle volcanic day, and the first Geng day after the beginning of autumn is the first day of the last volt, with 10 days per volt, but in some years it is 20 days, such as this year. Generally speaking, the average temperature of the "dog days" is the highest among the "dog days".

Of course, this calculation method of the ancients is not very scientific, and it is not necessarily closely integrated with the meteorological reality of the year, and the extreme maximum temperature in various places throughout the year does not necessarily appear in the "middle volt", or even in the "three dogs". But in any case, the "dog days" are indeed the time of the scorching heat in midsummer, and everyone should pay attention to heatstroke prevention and cooling.

The period from the third Geng day 2 to the day before the fourth Geng day after the summer solstice 1. The third Geng day is the first day of the first ambush.

The period of time before the fourth Geng day after the summer solstice to the first Geng day after the beginning of autumn 3. The fourth Geng day is set as the first day of the beginning of the middle volt, and if the autumn is established before the seventh lunar month, the middle volt is 10 days; The beginning of autumn after the seventh lunar month.

, the middle ambush is 20 days.

The period of time from the first day of the day of the beginning of autumn to the day before the day of the second day of the day. The second Geng day is set as the end of the Futian.

star821224-126: Hello.

The dog days are not in the twenty-four solar terms. Dog days and ninety-nine just stipulate the hottest and coldest time of the year. For example, on the summer solstice, three geng will count the volts. The winter solstice is nine.

The third Geng day after the summer solstice is the first day of the head volt every year; The fourth Geng day is the first day of the middle volt; The first Geng day after the beginning of autumn is the first day of the end of the year. Due to the different mornings and evenings after the summer solstice in each year, the time of ambush is not the same every year, the beginning of the first volt is generally in mid-July, the middle volt is in late July, and the last volt is mostly started in mid-August.

If you need a detailed answer, you can check my user profile or space, mobile phone or QQ contact.

The time of the ambush is not fixed every year, the length of the ambush is not the same, you need to check the almanac to calculate, you can simply use the "summer solstice three Geng" these 4 words mantra to indicate the date of the ambush, that is, from the third "Geng" day after the summer solstice, the first volcanic is 10 days, the middle volcanic is 10 days or 20 days, and the last volcanic is 10 days.

The 4th Geng day is the middle volt, and the 1st Geng day after the beginning of autumn is the last volt. When there are 4 Geng days between the summer solstice and the beginning of autumn, it is 10 days in the middle of the volt, and 20 days when there are 5 Geng days. It seems that the sooner or later appearance of Geng Day will affect the length of the middle volt, so there are 30 days of Futian in some years and 40 days in some years.

Calculation formula. 21st century new algorithm - Geng day formula: gr = (d - y 4]) mod 10 (gr Geng day, d even number year 1 singular year 6, y year, [ rounding, mod remainder)

Initial GR plus 10 (except for 2084), medium GR +20, and 9 when the last GR is greater than 7 minus 1 and less than 8 (2096 exception minus 1), e.g. 2006 GR = (1 - 6 4]) mod 10 = 0 (10), July 20, 30 days, and August 9.

First Days: July 18 - July 27.

Mid-volt: July 28 - August 6.

Last Resort: August 7 - August 16.

30 days please do not drink cold water drinks and food, will make the cold invasion can not be discharged, the reason why you are afraid of cold in winter, cold feet are caused by dog days, if you want to make the cold in the body discharge, please insist on drinking hot water in the dog days, it will force out the cold in the body for many years. Please cherish the annual Futian!

After the summer solstice, the third Geng day begins to set in ambush.

Counting from the beginning of the lunar summer, ten days is one volt.

Dog days are miscellaneous solar terms in addition to the twenty-four solar terms.

In order to regulate the climate, the ancients summed up the solar terms of the hottest period of the year according to the laws to be followed. Because of the long time span, it does not belong to the category of the 24 solar terms, so the dog days are miscellaneous solar terms. The dog days are divided into three segments, the first period, the second period, and the last period, dog days.

Dog days occur between the height of summer and the scorching heat, and are the highest, wettest, and most muggy days of the year. The so-called "dog days" refer to the "dog days" of the lunar calendar, which is the hottest time of the year. It can be understood like this:

"Volt" means that the weather is too hot and it is advisable to recuperate. Dog days are the hottest thirty or forty days of the year in the Central Plains. The dog days are calculated according to the lunar calendar, around the middle of July to the beginning of August in the solar calendar.

Dog Day Precautions

In China, summer is a very hot season, and Sanfu is the hottest period of summer. Temperatures during this period are usually very high, even reaching over 40. Therefore, people should pay attention to cooling down and maintaining good health at this time.

During the dog days, people will take some measures to cope with the hot weather, such as wearing loose and breathable clothes, drinking plenty of water, avoiding sun exposure, and reducing outdoor activities.

Dog days are also an important solar term in traditional Chinese culture. In ancient China, people would hold some festivals and sacrifices at this time, such as the "Three Dog Festivals" and so on. In addition, there are some folk traditions during the dog days, such as "eating jelly" and "drinking mung bean soup", which are all methods and customs to deal with hot weather.

It is the hottest, humid and muggy time of the year. "Volt"It means that the yin qi is forced by the yang qi to hide underground, and the three dogs are divided into the beginning, middle and end, and the date of its bending year is determined by the date of the solar terms of the Ganzhi calendar and the date of the Ganzhi era. "Ambush"After that, many places across the country will enter a sustained high temperature mode.

The traditional almanac states:"On the summer solstice, three Geng will count the volts", meaning to say,"From the summer solstice"Start counting backwards and count to the third"Geng day"And they began to ambush. Here"Geng day"Refers to the ancient"The method of the dry branch of the finch is the chronological method"with"G"The day of the prefix.

The length of the volcanic sky is mainly in the difference between the middle volts. Because the time of occurrence of the third Geng day (first volt) after the summer solstice solar term is different every year, the number of days that bury the bench leads to the middle volt is also different. The duration of the mid-volt period can be long or short, it may be 10 days or 20 days.

So there are some years when the day is 30 days, some years are 40 days, and there are two situations.

The three dog sources are not the 24 solar terms, but a set of production calendars established according to farming. When the dog days roll away, the weather will be hotter and more humid than hail, so pay attention to heat prevention when farming.

Hello, there are no dog days in the 24 solar terms, so the dog days are not solar terms, they are a climatic stage.
