How to calculate the year in ancient China, such as "Shen Jia"

Heavenly stems and earthly branches, referred to as Ganzhi for short, is used to arrange the year number and date in the summer calendar.

Tiangan is: A, B, C, D, E, G, G, Xin, Ren and Gui, also called Tiangan; The earthly branches are: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai, also known as the Twelve Earthly Branches. The branches are still divided into yin and yang: A, C, E, G, and nonyl belong to yang, while B, D, J, Xin, and Gui belong to yin; Zi, Yin, Chen, Wu, Shen and Xu are the Yang branches, while Ugliness, Mao, Si, Wei, You and Hai are the Yin branches. Heavenly stems and earthly branches collocation arrangement, heavenly stems in front of the soil branch behind, heavenly stems from a, soil branch from the child, Yang stem with Yang branch, Yin stem with Yin branch (Yang stem without Yin branch, Yin stem without Yang branch). There are sixty combinations called "Sixty Jiazi". In the past, people in China used to recycle calendar year, calendar month, calendar day and calendar time.

Tree trunk and branch chronology

For example, Jia Zi is the first year, Ugly B is the second year, and Bing Yin is the third year ... Sixty years is a week. When the week ends, it will start from the year of Jiazi, start from the week, and start again and again. For example, 1929 is the lunar year, 1930 is the year of Gengwu ... and 1989 is the lunar year. The four years and Gengwu years we see on the calendar are arranged according to the chronology of cadres and branches. Divide the Gregorian calendar year by the remainder of 60, and then subtract 3 to get the serial number of the monthly branch of that year, and then check the monthly branch above to get the age of the monthly branch. If the serial number is less than or equal to zero, add 60 to the branch serial number. For example, find 199 1 year; 199 1÷60=33 Remaining 1 1, annual serial number of main branch = 1 1-3=8. Check the list of cadres and branches, and you will know that this year is the year of Wei Xin. For another example, find the main branch of 1983: 1983÷60=33+3, and the main branch serial number =3-3=0, plus 60. Look up the main branch table, and know that the year is Guihai.

Dry-branch moon method

The method of tracking the moon by branches and branches has not been widely implemented, mainly for astrologers to calculate horoscopes. The method is as follows: if you meet A or your own year, the first month is C Yin; B or Geng Year, the first month is Wuyin; The first month of year C or Xin is Gengyin, the first month of year Ding Nian or Renyin is Renyin, and the first month of year E or Guiwei is Jiayin. The main branches of the first month are known, and the rest months can be inferred in the order of sixty jiazi.

Dry-branch method

The first day of onychomycosis, the second day of ugliness, the third day of Bingyin ... 60 days is a week. At the end of the week, it will start from Jiazi Day and continue. For example, in the fourth year of the lunar calendar (1989), the first day of the first month is Ding You Day, and the second day is the Day of the Reform Movement ... The seventh day of March is exactly 60 days, so the second day of March is Ding You Day again.

Chronology of cadres and branches

The earthly branches in daytime are also certain, so 24 hours are matched with 12 earthly branches, from 1 1 to 1 at night, from 1 to 3 o'clock, and the rest are pushed. A day in a day is inferred from a day, and its song is as follows:

A gave birth to A, and B, G and C were the first.

Bing Xin began in Wu and was born as a boxer.

You can't do it, but you can't.

That is to say, if the day is A's or his own, the child should be accompanied by A as a child; If the date is B or G, it should be accompanied by C; On the day of Bing Xin, Wu is the son of Wu; Ding Renri is a boxer; Pentecost is a seedless day. When you know the main branch of the child, you can infer the rest.
