Do you know the word "birthday"?
Date of birth, or constellation for short, refers to the calendar date when a person is born. This is actually the same meaning as the birthday we are talking about now.
In fact, the calendar uses heavenly stems and earthly branches to represent the year, month, day and time.
Ten days of work: A, B, C, D, E, Ji, G, Xin, people, ghosts.
Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.
This calendar represents time, and heavenly stems and earthly branches has one word for each. In order, it is from Jiazi, Emei ... to Guihai, which is exactly 60 groups in a cycle.
The year, month, day and hour are called "four pillars", and each pillar is represented by "a day's work+a place's branch", so it is called "eight characters".
Second, how to treat the "eight characters"
year

moon
From June 1 to June 12 (Lunar New Year), the ground branches are: silver moon, Uzuki, Chen Yue, Mitsuki, Noon, Yue Wei, Shen Yue, Youyue, Yuan Yue, Haiyue, Ziyue and Ugly Moon.

The monthly dryness can be calculated from the annual dryness, as shown in the following table.
For example, 20 18 is 1898, and the annual dry is "E", then the monthly dry on June 20, 20 18 (the seventh day of the fifth lunar month) is "E", which is the Wuwu month.
