How to calculate the chronology of trunks and branches

1. If you want to calculate the chronology of trunks and branches, you must first understand some basic knowledge. Ten people, including A, B, C, D, E, Ji, G, Xin, Ren and Gui, are called Tiangan; The twelve names of Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai are called earthly branches.

Both the heavenly stems and the earthly branches represent different numbers. The number of aerial stems from A to Gui is 4, 5, 6, 7, 8, 9, 10, 1 2, 3, and the number of aerial branches from A to Gui is 4, 5, 6, 7, 8, 9,/kloc-0,/kloc-0, respectively.

After knowing these basic knowledge, we can start to calculate. First, calculate the sky dryness. The sky dryness corresponding to the remainder obtained by dividing the year by 10 is this year's sky dryness. If this year is 20 17, you can divide it by17 and the remainder is 7, then the sky is dry this year.

4. The next step is to calculate the ground branch. The calculation method of earthly branches is similar to that of heavenly stems, except that 10 is replaced by 12. If 20 17, 20 17 is divided by 12 and the remainder is 1, then this year's earthly branch is zero.

The last thing to do is to combine the heavenly stems with the earthly branches. 20 17 years is 1898 if it is calculated by the year of dry expenditure.
