The traditional Chinese stem and branch chronology to be how to calculate?

A, what is the heavenly stem and earthly branch heavenly stem *** ten characters: a b c d e he yu xin nian nian kui these ten characters correspond to: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. earthly branch *** twelve characters: zi ug 寅 寅 辰 巳 午 未 申 酉戌 亥 These twelve characters correspond to: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. two, the method of stem and branch chronology the stem and the branch are used to calculate the year. Combined for the calculation of the year, ten dry and twelve branches in order with the combination of dry and branches, used for dating. 10 heavenly stems are arranged 6 times, 12 earthly branches are arranged 5 times to complete a cycle of exactly 60 years, that is, what we call 60 a jiazi, a cycle of 60 years, the cycle of the week again and again. Third, the dry chronology formula: dry chronology method is how to calculate? A method of calculation is: the calculation of the celestial trunk: the year minus 3 and then divided by 10 to get the remainder of the corresponding celestial trunk word is dry ground branch calculation: the year minus 3 and then divided by 12 to get the remainder of the corresponding ground branch word is the branch Example: 2008 calculation of the celestial trunk: (2008-3) / 10 of the remainder of the 5, corresponding to the word is the word of celestial trunk: E that is, for the dry calculation of the year's ground branch: (2008-3) / 12 of the remainder of the 1, the corresponding ground branch is the word is 1, corresponding to the Earth's branch is the word: Zi that is, for this year's stem so 2008 is the year of the Ezi four, the explanation of the formula of the stem and branch chronology method: colleagues asked me how this calculation method is obtained. I figured out the formula, and then checked the information, the year 4 AD is the first year of the 60 A Zi year: A Zi year so that we can carry out the calculation. First of all, the reason for the calculation of the celestial trunk: we know that the celestial trunk is 10, then every 10 years will cycle once, that is, the next A is 14 AD, in turn is 24 AD, etc., that is, the first digit is 4 corresponding to the celestial trunk is A, and then cycle in turn. If we use numbers to express, that is, let the number 1 of the heavenly stem "A" corresponds to the number 4 of the year, in this way, we do this treatment, 4 minus 3 to get 1. That is, the year minus 3, then the first digit of the year is 1, and then use the number of the year to express the residue of the year after dividing it by 10 is the first digit of the year, so the first digit is 4 to correspond to the number 1, so the first digit is 4 to correspond to the number 1. The reason for the calculation method of the Earthly Branches: we know that there are 12 Earthly Branches, so every 12 years there will be a cycle, i.e., the next Earthly Branches "Zi" is 16 AD, and then 28 AD, 40 AD, etc., and the cycle will be repeated every 12 years, and then the cycle will be repeated in that order. If we use numbers, the number 1 for the "son" of the earth's branch corresponds to the number 4 for the year 4 A.D., and the subsequent earth's branches will follow in order, and then the cycle will be repeated every 12 years. In this way, we do this treatment, the 4 of the year 4 AD minus 3 to get 1, that is, the year minus 3, then the year of the first digit is 1, so that the number of the year after dividing the number by 12 is the remainder of the first digit of the number of words 1, so the 4 of the year 4 AD to correspond to the number of the number of 1. For example: the year 2014 of the earth's branch. (2014-3)/12, the remainder of this equation is 10, so it corresponds to "You" in the Earthly Branch. Wuxu 己亥 庚子 辛丑 壬寅 癸卯
