What is the solstice this summer? What are the main branches?

What time is the summer solstice in 202 1 year? The following is the 202 1 Fu Tou from summer to Japan that I compiled for you. For reference only. Let's have a look.

1. Is the summer solstice the beginning of your stay?

Summer is not the beginning of autumn. This year's summer to sunset is on June 2 1 day, which is one of the 24 solar terms, indicating that the hot summer has arrived, but it is not the hottest time yet. Accommodation usually starts from the summer solstice and starts on the third Geng day.

2. How to calculate the three Geng of the solstice?

Entering summer, that is, entering the dog days, is divided into three days: morning, middle and evening, usually from mid-July to mid-August, which is the hottest time of the year. The time of squatting in dog days is not fixed every year, and the length of squatting in dog days is also different. There is a folk saying that "early autumn is the third day of summer solstice", which is the basis for establishing early autumn. It can be understood as "counting down from summer" and falling from the third "Geng Day". "Gengri" refers to the days prefixed with "Geng" in the ancient "Ganzhi Jiri Law", and every Gengri is separated by 10 days. The summer solstice this year is June 2 1, and the third Geng day is July 1 1, so the dog days of 202 1 start from July 1 1

1.202 1 fell at the beginning of the year.

July 1 1 (the second day of June)-July 20th (11month), with a total duration of 10 days.

2.202 1 year medium pressure

July 2 1 (June12)-July 30 (June 21), with a total duration of 10 days.

3.20 1 leap year

July 3 1 (June 22, lunar calendar)-August 9 (the second day of July, lunar calendar), with a total duration of 10 days.

Note: Summer days are generally not fixed. Between the summer solstice and the beginning of autumn, there are four shifts, namely, midsummer 10 days, midsummer 20 days and five shifts. So at 202 1, there will be 20 days of summer.

4.202 1 final voltage

August 10 (the third day of the seventh lunar month)-August 19 (the second lunar month), with a total construction period of 10 days.

It can be concluded that the lodging time of 202 1 dog days is July 1 1 and the lodging time is August 19.
