What is the method of the ancient Chinese Heavenly Branch and Earth Stem Chronology?

The sexagenary chronology is also called the "Stem-branch chronology".

1. The chronology of cadres and branches is the traditional method of dating in China.

1 Meaning of stem and branch: Stem branch is the collective name of the heavenly stem and the earthly branch.

Stem refers to the heavenly stem, and there are 10 symbols:

A, B, C, D, pente, heptyl, xin, nondecan.

The branch refers to the earthly branch, with a total of 12 symbols:

Zi Chou Yin Mao Chen Si Wu did not apply for Youxu Hai.

2 The combination of stem and branch is used for chronology. That is, the ten heavenly stems and the twelve earthly branches are combined in order to form a dry branch, which is used for the chronology.

According to this arrangement, after the 10 symbols of the stem of the day are lined up for six rounds and the 12 symbols of the earth branch are arranged for five rounds, it can constitute 60 stem branches. It will continue to be reverted to its original state, and the cycle will start over and over again, that is, as the folk say, "sixty years to Jiazi".

2. View perpetual calendars for different time periods. For example, the perpetual calendar from 1516 to 2060 records the cadres and branches of 500 years, and you can know it when you check it.

Sixty years of Jiazi (dry branch table).

Jiazi, Yichou, Bingyin, Ding Mao, Wuchen, Jisi, Gengwu, Xinwei, Renshen, Guiyou.

Jiaxu, Yihai, Bingzi, Ding Chou, Wuyin, Jimao, Gengchen, Xinji, Renwu, Guiwei.

Jiashen, Yiyou, Bingxu, Dinghai, Wuzi, Jichou, Gengyin, Xinmao, Renchen, and Guisi.

Jiawu, Yiwei, Bingshen, Ding You, Wuxu, Jihai, Gengzi, Xin Chou, Renyin, Gui Chou.

Jiachen, Yisi, Bingwu, Ding Wei, Wushen, Jiyou, Gengxu, Xinhai, Renzi, Guichou.

Jiayin, Yimao, Bingchen, Ding Si, Wuwu, Jiwei, Gengshen, Xinyou, Renxu, Guihai.

According to the corresponding year of the first year of the "Sixty Years of Jiazi (Dry Branch Table)", it is reversed upwards or downwards. For example, the Xinhai year of the "Xinhai Revolution" is 1911 (No. 48 Ganzhi), and the Wuxu year of the "Wuxu Reform Law" is No. 35 Ganzhi, which is 13 years earlier than the Xinhai year, then "1911-13=1898" so the "Wuxu Reform Law" is 1898.

The calculation should be made using the A.D. year. Apply a certain year in the year of the Common Era, talk about 60 (referring to the sixty years of Jiazi), the remainder is less than 60, and then subtract 3 from the remainder (the Ganzhi year is used from the 4th year of the AD), you know.

For example, in 2002: 2002 60, the remainder is 22, and then 22-3, the number is 19, check the 60-year Jiazi (cadre branch table) No. 19 cadre branch, and learn that it is the year of Renwu.

1. The Ganzhi chronology method has been used in the Chinese calendar since ancient times. Ganzhi is a general term for the heavenly stem and the earthly branch. The sequence of the stem branch is matched exactly sixty times a week, and the cycle is repeated, and the cycle is recorded, which is commonly known as the "stem branch table".

The Ganzhi year is changed from the beginning of spring to the beginning of spring every year.

2. The heavenly stems and earthly branches are as early as 2697 B.C., when the Chinese ancestor Yellow Emperor founded the country, he ordered the Daluo clan to explore the qi of heaven and earth, ** the five elements (gold, wood, water, fire and earth), starting with A, B, C, D, E, G, XIN, NON, and decay and other ten heavenly stems, and Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai and other twelve earthly branches, which cooperate with each other into sixty Jiazi for the symbol of the calendar.

3. The calendar uses the heavenly stem and the earthly branch to arrange the year number and date, and the heavenly stem has a total of ten characters, so it is also called the ten stems, and its order is: A, B, C, D, E, H, G, XIN, NON, and DE; There are a total of 12 characters in the earthly branch, and the order is: Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai.

Among them, A, C, E, G, and non are yang stems, and B, D, H, XIN, and dec are yin stems. Zi, Yin, Chen, Wu, Shen, and Xu are the yang branches, and Chou, Mao, Si, Wei, You, and Hai are the yin branches.

4. With a stem and an earthly branch matched, arranged, the heavenly stem is in the front, the earthly branch is in the back, the heavenly stem is from the first, the earthly branch is from the son, the yang stem is against the yang branch, and the yin stem is against the yin branch (the yang stem is not matched with the yin branch, and the yin stem is not matched with the yang branch) to obtain a 60-year cycle of jiazi circle. It is called "Sixty Jiazi" or "Flower Jiazi". In the past, the people of our country used to record years, months, days, and hours in a cycle of 60 jiazi.

5. The twenty-two symbols of the sexagenary branch are intricate and orderly, full of harmony and regularity. It shows the laws of nature, the interaction of time (time) and space (direction), and the results of the action of yin and yang. The Chinese calendar contains the idea of the five elements of yin and yang and the laws of natural circulation.

6. Year: Each stem branch is one year, and after sixty stems, it is counted from the beginning, and the cycle is endless. Starting from Jiazi, it is called Yijiazi or Yihua Jiazi after 60 years. It is called the Ganzhi chronology.

7. Month: The first month of the first month starts from Yin, and the earthly branch of each month is fixed, and then combined with the heavenly stem in turn; From the first month of the first year, the month of Bingyin, February is the month of Dingmao, and the month of March is Wuchen. From the month of Jiazi to the month of Guihai, a total of sixty Jiazi, just five years.

8. Day: Starting from Jiazi Day, it is arranged in order, and 60 days is just a cycle of dry branches.

9. Time: It starts from the Jiazi time, but the earthly branch of the time is fixed, twelve hours a day.
