How to calculate the dog days of 20 14?

Calculation of dog days (using 20 10-20 14 dog days schedule)

"crouching" means being forced to hide underground, which is the hottest season in a 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. The word "Geng" on Geng Day is the seventh word in ten days of "A, B, C, D, E, Ji, Geng, Xin, Ren and Gui", and Geng Day is repeated every ten days.

The start and end time of the dog days is different every year, roughly from mid-July to mid-August. How exactly is it worked out? China's popular "Ganzhi Diri method" records dates with 60 groups of different names, and each day with the word Gengzi is called Gengri.

During the Qin and Han dynasties, there was a popular saying that "the five elements are mutually reinforcing". People think that the hottest day in summer belongs to fire, while Geng belongs to gold. Gold is afraid of being melted by fire, so on Geng Day, gold will be hidden. Therefore, it is stipulated that from summer to the third Geng day in the future, it is the initial lodging (with 10 day), and from summer to the fourth Geng day in the future, it is the intermediate lodging (with 10 day in some years and 20 days in some years), and the first Geng day after beginning of autumn is the final lodging, also known as the final lodging (with 10 day).

When there are four Geng days between summer solstice and the beginning of autumn, the middle part is 65,438+00 days, and when there are five Geng days, the middle part is 20 days. So sometimes it is ten days from the middle to the end, sometimes it is twenty days, and both "head" and "tail" are 65,438+00 days.

The first is the debut this year.

Today's summer solstice is June 2 1 in Gregorian calendar, and June 20, June 30, July 10 and July 20 are Geng Day. Obviously, July 20th is the third Geng Day after the summer of this year, which is the "dog days"-the first day of this year.

Second, medium.

Obviously, July 30th of the Gregorian calendar is the fourth Geng day from summer to the future, that is, the day of falling.

The period from July 30th to August 9th is 10 days, that is, 10 days in the middle range and 30 days in dog days.

Third, the last volt

This year's Gregorian calendar begins on August 7 in autumn, and then the third day, August 9, is Geng Day. Of course, this day enters the closing stage, which is also the last stage of this year. Gregorian calendar August 18 This year's "dog days" are over.

Fourth, Qiu

There is an old saying in Chengdu that "autumn is crisp, autumn is crisp and you want to cry", which means that according to the China lunar calendar, "rainy days" begin first. This year, the solar terms in beginning of autumn are sandwiched between thirty or forty rainy days, so the weather must not be too hot or too cold. The reason is that autumn comes earlier, the temperature is naturally not as hot as the summer heat, and the human body is easy to accept and adapt. On the contrary, if "Fu Tian" is postponed and "Fu" is included in autumn in the first half of the lunar calendar, the weather will be very hot. And the temperature adjustment period is longer.
