birthdates just used heavenly stems and earthly branches to express the time of our birth.
There are ten heavenly stems, which refer to A, B, C, D, E, G, Xin, Ren and Gui;
There are twelve earthly branches, which refer to Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. Among them, the traditional culture also uses the twelve zodiac signs to represent the earthly branches, namely, the mouse, the ugly cow, the yinhu, the maotu, the dragon, the snake, the afternoon horse, the sheep, the monkey, the chicken, the dog and the sea pig.
Let me give you a small example. For example, I was born at 3: 53 on December 23rd, 1976, which is expressed by heavenly stems and earthly branches as the year of Bing Chen, the month of Geng Zi, the day of Ji You and the time of Bing Yin. This year, month, day and hour contain four heavenly stems and four earthly branches, which add up to eight words, so they are called eight characters. These eight characters are brought by human nature, from which we can see the fate of human life.
Simple chart
How to calculate it exactly?
The annual trunk branch
subtracts 3 from the known year, and then the remainder after dividing by 1 is the heavenly stem, and the remainder after dividing by 12 is the earthly branch (if exactly divisible, it is the last digit).
For example, in 27, 27-3=24 and then 1+4 is the digit of Ding in the heavenly stem, and the digit of Hai is divided by 12+.
monthly branch
After calculating the annual branch, you can know that the leftmost column in the monthly branch table
