How to calculate heavenly stems and earthly branches's date of birth?

Chronology of ancient China. That is, Party A, Party B, Party C, Party D, Party E, Party B, Party G, Party A, Party B and Party B are ten, while Party A, Party B, Party C, Party B, Party C, Party D, Party B, Party B and Party B are twelve, and the branches are coordinated in sequence. Such as Jia Zi and Yi Chou, will return to Jia Zi after 60 years. It goes on and on. In China, the lunar calendar still uses the calendar year of cadres and branches.

The chronology of the dry branch sprouted in the Western Han Dynasty, began with Wang Mang, and prevailed in the late Eastern Han Dynasty. In the second year of Emperor Yuanhe of the Han and Yuan Dynasties (AD 85), the court ordered the nationwide implementation of the chronicle of cadres. Some people think that China used dry branches to record the years before Emperor Wu of the Han Dynasty. However, this is the Gregorian calendar year of the Prince, which is based on the Gregorian calendar year of the Prince, and the branch represents twelve days (the ecliptic is divided into twelve equal parts). Jupiter 1 1.862 revolves around the sky once a week, so it takes about 86 years for Tai Sui to pass through an old age, which is the so-called "Chen Chao". In the Calendar of Zhuan Xu, the first year of Tai Chu (BC 104) of Emperor Wu of the Western Han Dynasty was the prince of Bingzi, and taichu calendar changed it to Ding Chou by surpassing Chen. At the end of the Han Dynasty, Liu Xin changed the first year of Taishu to Bingzi, and the second year of Taishi (the first 95 years) from Yiyou to Bingxu. Scholars who returned to the eastern Han dynasty did not use the super-Chen method. So from the second year, the chronology of the prince and the chronology of the main branch are the same. However, according to legend, the chronology expressed by heavenly stems and earthly branches began in the period of the Yellow Emperor, and 60 pieces of Jiazi table were found in Shang Dynasty archaeology in Yin Ruins.

1. The meaning of trunk and branch: trunk and branch are the general names of heavenly stems and earthly branches.

There are 10 symbols:

1 2 3 4 5 6 7 8 9 10

Methyl ethyl propyl butyl hexyl heptyl octyl non decyl

Branch refers to the ground branch with 12 symbols:

1 2 3 4 5 6 7 8 9 10 1 1 12

The child is ugly, and the mother hasn't applied this afternoon.

2. The combination of stem and branch is used for dating. That is to say, the ten-day stem and the twelve-day branch are combined to form the stem and branch for dating. According to this arrangement method, 60 branches can be formed after six rounds of arrangement 10 symbols and five rounds of arrangement 12 symbols for ground branches on the same day. If it continues to be discharged, it will return to its original state again and again, which is what the folks call "sixty years of turning to Jiazi".

[Edit this paragraph] Understand the "Twelve Branches" in combination with the actual situation

1. Match twelve animals with twelve earthly branches to form the Year of the Zodiac. (See the picture below) If the year of the main branch contains the word "zi", it is the year of the rat, and all the people born in this year are "rats"; The Year of the Ox is a year of ugliness, and all the people born in this year belong to the ox. And so on. (as shown in the following table)

Zodiac year

1 2 3 4 5 6 7 8 9 10 1 1 12

Rat, ugly cow, black snake, black horsetail, Yang Shen Houyou chicken, Gou Haizhu

2. Twelve branches represent twelve o'clock.

There are twenty-four hours in a day, but in our tradition, it is represented by twelve hours, that is, one hour is two hours. (as shown in the following table)

24-hour and 12-hour comparison table

Ugly son, ugly son, ugly son, ugly son.

At noon, I didn't apply.

1 1- 13: 13- 15: 15- 17: 17- 19: 19-2 1:2 1-23

[Edit this paragraph] The conversion between the AD chronology and the main branch chronology.

1. Proof of heavenly stems

The sky is dry according to the figures at the end of the year.

BC:

0 is Xin, 1 Geng, 2 is Ji, 3 is E, 4 is D, 5 is C, 6 is B, 7 is A, 8 is decyl and 9 is nonyl.

After A.D.:

0 is heptyl, 1 is octyl, 2 is nonyl, 3 is decyl, 4 is A, 5 is B, 6 is C, 7 is D, 8 is E, and 9 is self.

2. Ground branch calculation

Earthly branches can be divided into odd-numbered and even-numbered arrangements. (After A.D., odd-numbered spouse array, even-numbered spouse array. The situation in BC is just the opposite. )

Odd array: even array:

1 2 3 4 5 6 1 2 3 4 5 6

Zi Wu's ugly hair is not yet unitary.

When calculating the ground branch, divide the year and the last number by 6 (for example, divide 2009 by 6 in 2009). Divide by 6 to get the remainder, and you can get the ground branch.

However, due to the different final figures, the branches obtained are also different. It can be concluded that:

BC:

The last digit is 0, 1, the remainder 0 is fifth, the remainder 1 is sixth, the remainder 2 is 1, the remainder 3 is second, the remainder 4 is third and the remainder 5 is fourth.

The last digit is 2,3, the remainder 0 is the fourth, the remainder 1 is the fifth, the remainder 2 is the sixth, the remainder 3 is 1, the remainder 4 is the second and the remainder 5 is the third.

The last digit is 4,5, the remainder 0 is the third, the remainder 1 is the fourth, the remainder 2 is the fifth, the remainder 3 is the sixth, the remainder 4 is 1, and the remainder 5 is the second.

The last digit is 6,7, the remainder 0 is the second, the remainder 1 is the third, the remainder 2 is the fourth, the remainder 3 is the fifth, the remainder 4 is the sixth, and the remainder 5 is 1.

The last digit is 8,9, the remainder 0 is 1, the remainder 1 is the second, the remainder 2 is the third, the remainder 3 is the fourth, the remainder 4 is the fifth and the remainder 5 is the sixth.

After A.D.:

The last digit is 0, 1, the remainder 0 is fifth, the remainder 1 is fourth, the remainder 2 is third, the remainder 3 is second, the remainder 4 is 1, and the remainder 5 is sixth.

The last digit is 2,3, the remainder 0 is the sixth, the remainder 1 is the fifth, the remainder 2 is the fourth, the remainder 3 is the third, the remainder 4 is the second, and the remainder 5 is 1.

The last digit is 4,5, the remainder 0 is 1, the remainder 1 is the sixth, the remainder 2 is the fifth, the remainder 3 is the fourth, the remainder 4 is the third and the remainder 5 is the second.

The last digit is 6,7, the remainder 0 is the second, the remainder 1 is 1, the remainder 2 is the sixth, the remainder 3 is the fifth, the remainder 4 is the fourth and the remainder 5 is the third.

The last digit is 8,9, the remainder 0 is the third, the remainder 1 is the second, the remainder 2 is 1, the remainder 3 is the sixth, the remainder 4 is the fifth and the remainder 5 is the fourth.

Formula: After AD: 05-26-4 1-62-83, that is, the residue of the last digit 0 or 1 is the fifth, the residue of the last digit 2 or 3 is the sixth, the residue of the last digit 4 or 5 is 1, and the residue of the last digit 6 or 7 is the second.

BC: 05-24-43-62-8 1, with the same meaning as above.

So you can work out the year.

For example, in 2009, Tiangan Jiu was his own, and then 200 ÷ 6 = 33 ... 2. The one with 9 and 2 at the end after AD was the first, and the even array was the first ugly. Calculate the earthly branch. Together, it is an ugly year.

Answer: 2009 was an ugly year.

[Edit this paragraph] Quickly check the lunar calendar method of cadres and branches.

Since the Shang calendar, the first month of each year has been designated as Yin, which is called "building Yin in the first month", and the subsequent months are analogized in the order of earthly branches. The calculation method of the dryness of the first month is as follows: if it meets the year of Party A or its own side, the first month is C Yin; B or Geng Year, the first month is Wuyin; In the year of C or Xin, the first month is Geng Yin; Ding Nian or Ren Nian, the first month is Renyin; In the year of 1898 or 1998, the first month was Jiayin. The first month is calculated according to the main branch, and other months can be calculated according to the main branch.

For example, 2006 is the year of Xu Bing, Geng Yin in the first month, Xin Mao in February, Ren Chen in March, and so on.

[Edit this paragraph] Quickly check the calendars of cadres and branches.

The formula for calculating the branch date from the known date is:

g = 4C+[C/4]+5y+[y/4]+[3 *(M+ 1)/5]+d-3

z = 8C+[C/4]+5y+[y/4]+[3 *(M+ 1)/5]+d+7+I

Where c is the number of centuries minus one, y is the last two digits of the year, m is the month and d is the number of days. 65438+ 10 and February are calculated according to 65438+March and 65438+April of the previous year. Odd months i=0 and even months i=6. The remainder of g divided by 10 is heavenly stems, and the remainder of z divided by 12 is earthly branches.

When calculating, the number with [] indicates rounding.

For example, check the trunk and branch days of April 1 day, 2006. Substitute the numerical value into the calculation formula.

g = 4 * 20+[20/4]+5 * 06+[06/4]+[3 *(4+ 1)/5]+ 1-3 = 1 17

Divided by 10, the remainder is 7, and the seventh place is' Geng'.

z = 8 * 20+[20/4]+5 * 06+[06/4]+[3 *(4+ 1)/5]+ 1+7+6 = 2 13

Divided by 12, the remainder is 9, and the ninth branch is' Shen'.

The answer is: April 2006 1 day is Geng Shen day.

Relatively simple chronology of AD and BC.

Chronology of branches and branches in AD:

For example, in 2000 (), the red part of 2000 is Tiangan, which means Geng 0: 2000 divided by 12 equals 166, which means Chen 8.

Chronology of BC:

For example: 78 BC1(Geng Shen) 78 1 Tiangan:1-1=10, that is: Geng 0 earthly branch: 78 1 divided by/

In 3 14 BC (Ding Wei), Tiangan: 1 1-4=7, that is, the earthly branch of Ding 7: 3 14 divided by 12 equals 26 remaining 2, that is,13-2.

In 57 BC (Jiazi), the heavenly stems: 1 1-7=4 (Jiazi), and the earthly branches: 57 divided by 12 equals 4+9 13-9=4 (Zizi).
