What are the specific days of entry and exit from 2065438+2008?

"Because the date of Gengri in the solar calendar changes every year, the date of entry is different every year, but they all enter in mid-July." Zhao Zhi Heng, an expert in astronomy education and director of Tianjin Astronomical Society, said:

The first and last days are 10 days, and the intermediate days are not fixed. When there are four Geng days between the summer solstice and beginning of autumn, the bisection point is 10 day; When there are five Geng days, the intermediate period is 20 days. There are five more days from the solstice in summer to the beginning of autumn this year, so this year's Mid-Autumn Festival is 20 days.

Specifically, the dog days of 20 18 are 17' s first squat, July 27' s middle squat, 16' s last squat and August 26' s coming out.

The origin of three volts:

The specific date of "Sanfu" is determined by the solar term date and the dry branch date. Geng, ranked seventh in the heavenly dryness, belongs to gold in the collocation with the five elements, and gold is afraid of fire, which decreases day by day in the weather of several volts, so the ancients counted Geng Day as "volt".

According to the traditional calculation method, it is called "initial lodging" from summer to the third Geng day in the future, "intermediate lodging" from summer to the fourth Geng day in the future, and "final lodging" from the first Geng day after beginning of autumn, which is always called "three volts".

The dog days are characterized by high temperature, low air pressure, high humidity and low wind speed, which is the hottest season in a year. Health experts reminded that at this time, the public should pay special attention to heatstroke prevention and cooling, light diet, timely hydration, attention to potassium supplementation, eat more bitter food, sleep regularly, and minimize unnecessary outings during high temperature periods.
