What is the first year of China's traditional Ganzhi calendar?

1. Ten chronologies are the traditional chronology method in China.

1. meaning of stem and branch: stem and branch are the collective names of heavenly stem and earthly branch.

dry refers to heavenly stems, and * * has 1 symbols:

1 2 3 4 5 6 7 8 9 1

methyl-ethyl-propyl-butyl-heptyl-octyl-nonyl-decyl

refers to earthly branches, and * * has 12 symbols:

1 2 3 4 5 6 7 8 9 1 11 12

It's not noon yet. That is, the ten-day stem and the twelve-day branch are combined in order to form the stem and branch for dating. According to this arrangement method, 6 branches can be formed after six rounds of arrangement of 1 symbols and five rounds of arrangement of 12 symbols of ground branches on the same day. If it continues to be discharged, it will be restored to its original state, and it will be repeated again and again, that is, as the folks say, "turning to Jiazi in 6 years."

2. check the perpetual calendar in different time periods. For example, in the calendar from 1516 to 26, we can remember the 5-year-old branches and branches, and we can know them by looking them up.

According to the corresponding year of the "Sixty Years Jia Zi (Branch Table)". For example, the year of Xinhai Revolution was 1911 (No.48 trunk branch), and the year of the Reform Movement of 1898 was No.35 trunk branch, which was 13 years earlier than the year of Xinhai, so the Reform Movement of 1898 was 1911-13=1898.

the calculation shall be made in the year of AD. In a certain year of AD, we can talk about 6 (referring to 6 years), the remainder is less than 6, and then subtract 3 from the remainder (the calendar year of trunk and branch began to be used in AD 4).

for example, 22: 22÷6, the remainder is 22, and then 22-3, the number is 19. If you look up the No.19 branch of Jiazi (branch list) in the past 6 years, you know that it is the year of Renwu.

3. Understand the "Twelve Earthly Branches" in combination with reality

1. Match twelve kinds of animals with the twelve earthly branches to form the "Year of the Zodiac". (See the picture below) If the year of the trunk and 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 the year of the stem and branch that contains ugliness, and all the people born in this year belong to the ox. And so on. (as shown in the table below)

The ugly cow, the mouse, the tiger, the fur rabbit, the dragon, the snake, the afternoon horse, the sheep, the monkey, the chicken, the dog and the pig

2.

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)

Wu Hai was not applied for at noon

11-13. Counting the year from the A.D. < P > In order to facilitate the calculation and make the retrieval more intuitive, Borrow the 6-branch table and number it into Table 1 in sequence as follows:

Jia Zi E Chou 1 C Yin 2 Ding Mao 3 E Chen 4 Ji Wu Geng Wu 6 Xin Wei 7 Ren Shen 8 Gui You 9

Jia Xu 1 Yi Hai 11 C Zi 12 Ding Chou 13 E Yin 14 Ji Mao 15 G Chen 16 Xin Si 17 Ren Wu 18 Gui Wei 19

. Zi 24 Ji Chou 25 Geng Yin 26 Xin Mao 27 Ren Chen 28 Gui Si 29

Jiawu 3 Yi Wei 31 Bing Shen 32 Ding You 33 Wuxu 34 Ji Hai 35 Geng Zi 36 Xin Chou 37 Ren Yin 38 Gui Mao 39

Jiachen 4 Yi Si 41 Bing Wu 42 Ding Wei 43 Wu Shen 44 Ji You 45 Geng Xu 46 Xinhai 47 Ren. 2 ding si 53 Wu Wu 54 has not been 55 Geng Shen 56 Xin you 57 ren Xu 58 GUI hai 59

this table is applicable to the calculation before and after the ad, and the specific methods are as follows:

1. Find the stem and branch of a year after the ad (set as y). The method is: divide y by 6 to get the remainder, then subtract 4, and finally look up the stem corresponding to the corresponding ordinal number in Table 1 according to the obtained result, which is the stem of the year.

for example, to find the trunk and branch in 1911: the remainder of 1911÷6 is 51, and after subtracting 4, 47 is obtained. Look up Table 1. The corresponding trunk and branch of 47 is Xinhai, that is, 1911 is the year of Xinhai. Because of the 6-year cycle of the trunk and branch years, when the remainder of Y÷6 is less than 4, it is necessary to borrow the number of 6 in a cycle of the trunk and branch years, for example, if 1981 is divided by 6, the remainder is 1, and directly subtracting 4 is not enough to reduce it. After adding 6, subtracting 4 is equal to 57. Look up the table and you will know that 1981 is Xinyou year. I can be analogized.

2, find the stem and branch of a certain year BC (set as X). The method is: divide X by 6 to find the remainder, then subtract the remainder from 57, and then look up the corresponding branches in Table 1 according to the obtained results, which is the branches of the year.

for example, to find the trunk and branch in 221 BC: 221÷6, the remainder is 41, and 57-41 = 16. Look-up table 1-16 corresponds to Geng Chen, that is, the trunk and branch corresponding to 221 BC should be Geng Chen. Similarly, because the cycle of the trunk and branch chronology is 6 years, when the remainder is greater than 57, it is necessary to borrow another 6. For example, to find the main branch in 479 BC (the year of Confucius' death): 479 divided by more than 6 59, 57 minus 59 is not enough to reduce, and 59 minus 6 equals 58. Look up the table and know that the corresponding main branch in that year is Renxu. The rest can be analogized.

The above method is simple and easy. As long as you remember Table 1, you can deduce the results directly by mental arithmetic without paper and pencil.

5. Quickly check the lunar calendar of the cadres and branches

The method is as follows: If you meet the year of Party A or Party B, the first month is Bing Yin; In the year of B or G, the first month is Wuyin; In the year of C or Xin, the first month is Geng Yin; In the year of Ding or Ren, the first month is Ren Yin; In the year of e or decyl, the first month is Jiayin. According to the main branch of the first month, the other months can be calculated according to the main branch.

for example, 26 is the year of Bingxu, with Gengyin in the first month, Xinmao in February, Renchen in March, and so on.

VI. Quickly check the date of the trunk and branch

The formula for calculating the date of the trunk and branch is:

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

z = 8c+[ January and February are calculated according to March and April of the previous year. Odd months i= and even months i=6. The remainder of g divided by 1 is heavenly stem, and the remainder of z divided by 12 is earthly branch.

when calculating, the number with [] indicates rounding.

for example, check the dry branch day on April 1st, 26. Substitute the numerical value into the calculation formula.

g = 4 * 2+[2/4]+5 * 6+[6/4]+[3 * (4+1)/5]+1-3 = 197

If you divide it by 1, the remainder is 7, and the seventh place in Tiangan is' Geng'.

z = 8 * 2+[2/4]+5 * 6+[6/4]+[3 * (4+1)/5]+1+7+6 = 213

If you divide by 12, the remainder is 9, and the ninth place of the earthly branch is Shen.

the answer is: April 1st, 26 is Gengshen Day.
