How dog days are calculated and how dog days are calculated

The dog days are calculated from the third "Geng" day after the summer solstice, with the first volcanic being 10 days, the middle volcanic being 10 days or 20 days, and the last volt being 10 days.

Dog days are the hottest and humid days of the year. The so-called "Fu Tian'er" refers to the "dog days" of the lunar calendar, that is, the hottest period of the year.

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 (the first volt) after the summer solstice solar term is different every year, the number of days leading to the mid-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 date of the dog days is calculated by combining the solar terms date of the Ganzhi calendar with the date of the Ganzhi day. According to the traditional almanac, the third Geng day after the summer solstice begins to enter the ambush, 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 Fushino zone.

Dog days, most of them appear between the summer heat and the heat, is the highest temperature and humid and sultry time in the year, the word Fu has the meaning of yin and yang forced by yang, hidden in the ground, there is a volt, two volts, three volts.

The length of the three songs is mainly due to the difference in the middle of the volt, because the time of the first volt after the summer solstice solar term may be different every year, so the number of days leading to the middle volt is also different, it may be 10 days, it may be 20 days, or even longer.

Dog days, the climate in the southern part of China is characterized by high temperature and high humidity, and the climate in the northern region is characterized by high temperature and dryness.

The dog days refer to the three dog days refer to the general term of the beginning, middle, and end.

The 3rd Geng day after the summer solstice will enter the ambush, and the 4th Geng day after the summer solstice will enter the middle volcane; After the beginning of autumn, the first day of the eggplant Geng enters the end of the day, and the second day of the sun rises after the beginning of autumn.

The character "庚" on the day of Geng is the seventh character of the 10 heavenly stems of "A, B, C, D, E, G, G, G, XIN, NON, and 癸", and is repeated every 10 days. 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. The morning and evening of the Geng day will affect the length of the middle volt, so there are 30 dog days in some years and 40 days in some years.

The second algorithm is Zen.

The new algorithm of the 21st century - Geng day formula: gr = (d-[y 4]) mod10 (gr Geng day, d even number year 1 singular year 6, y year, rounding, mod remainder).

The initial volt gr is added to 10 (the exception is not added in 2084), the middle volt gr is +20, and the last volt gr is greater than 7 minus 1 is less than 8 (2096 exception minus 1), for example, in 2006 gr = (1-[6 4]) mod10 = 0 (10), the first volt is July 20, the middle volt is 30 days, and the last volt is August 9.

From the beginning of the summer solstice, the days are short and the nights are long, and there is a cold factor lurking in the middle of the heat. This statement has a long history in our country. As early as the Qin Dynasty, the hottest time of the year was called Futian.

Summary. I'm a teacher who asks a question and answer, and the master life expert is Xiongzi. The process of ambush and subterranean weather is not a set of standards for the process of summer and high temperature in meteorology. Futian is determined in accordance with the ancient "Ganzhi Chronological Law" in China.

I'm a Q&A teacher, a master of life and a life expert, Xiongzi. The process of ambush and subterranean is not a set of standards with the process of inset summer and high base field temperature in meteorology. Futian is determined by Zhihui in accordance with the ancient "Ganzhi Chronological Law" in China.

Folk proverb cloud: "Summer solstice three Geng several heads". However, the process of ambush and volcanic weather in the folk and the process of summer and high temperature in meteorology are not a set of standards.

Futian is determined in accordance with the ancient "Ganzhi Chronological Law" in China. Every year after the summer solstice, the third Geng day (referring to the day with the word "Geng Mao Sui" 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 is called the three dogs. According to the solar calendar, the group rises from mid-July to mid-August, and the time is "one size fits all" regardless of region.

The beginning of summer in the sense of the old phenomenology of the collapse refers to the steady rise of the daily average temperature to more than 22 degrees Celsius for 5 consecutive days as the beginning of summer.

According to the statistics of the China Meteorological Administration, China's first regional high temperature weather process this year is 16 days earlier than usual. As the saying goes, "the heat is in the dogs".

Dog days tend to be very hot, because after the ambush, the surface absorbs more heat per ear of poor days, and the heat of the scattered blind people is less, and the heat in the surface layer continues to accumulate, so it is getting hotter day by day. Entering the dog days, the heat accumulated on the ground reaches its peak. As the temperature increases, the atmospheric circulation also changes, mainly due to the south-to-north oscillation of the subtropical high.

Around June 18 this year, the south entered the plum rainy period, and the subtropical high was relatively stable, resulting in frequent heavy rainfall in southern China. The northern part is affected by the upper-air cold vortex, and sporadic process thunderstorms are also frequent. Mills.

The dog days are calculated as follows: the dog days are divided into the beginning, the middle and the end, and the saying goes, the heat is in the dog days. The date of Fu was calculated by the people of the ancient Qing Dynasty in China according to the Ganzhi Chronicle method.

Stem is the heavenly stem, i.e., A, B, C, D, E, G, G, XIN, NON, and DE; The branch is the earthly branch, that is, Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai. The ancients used a combination of the heavenly stem and the earthly branch to represent the date, and the sixty potatoes were not a cycle, which was called sixty jiazi. The first answer is Ashifu:

July 11, 2023 - July 20, 2023, a total of 10 days; Zhongfu: July 21, 2023 - August 9, 2023, a total of 20 days; Last day: August 10, 2023 - August 19, 2023, a total of 10 days.

Summary. The dog days are calculated according to the lunar calendar, which is about the beginning of July to the middle and bottom of August of the solar calendar.

The dog days are calculated according to the lunar calendar, which is about the beginning of July to the middle and bottom of August of the solar calendar.

Dog days appear in the summer and heat, the so-called "Fu Tianer", is the type of fight refers to the lunar calendar "dog days", that is, the hottest time of the year. It can be understood in this way: "volt" means that the weather is too hot, and it is not suitable to move.

However, the reason why dog days are called "volts" is because there are also many cold factors in the section of sales.

The time of "ambush" is calculated according to the date of the base liquid gas and the date of the dry branch, and it is necessary to calculate the noise from the "Geng day". Wen Blind Feng has the highest degree of service, 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.
