12 What is the zodiac? What is heavenly stems and earthly branches?

To understand this, you need to know what heavenly stems and earthly branches is.

Ten days of work: A, B, C, D, E, F, G, Xin, N, D.

Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

The twelve earthly branches correspond to the zodiac: mouse, ox, tiger, rabbit, snake, horse, sheep, monkey, chicken, dog and pig.

The arrangement of ten heavenly stems and twelve earthly branches from Jiazi to Guihai is exactly 60 groups, so 60 years is a Jiazi, and the same arrangement is also used to record the sun and the moon. The combination arranged on the first day of the year/month can be used to represent the year/month. For example, the first day of 1984 is Jiazi Day, and Jiazi corresponds to a mouse, so 1984 is the year of the mouse. The year of the topic is not quite right. It is necessary to add the year, month and day to the sky and write them down as two words. For example, 1986 is the year of the third year, and the year number of the ancient emperor of China can be added to keep the record in order.

As for Yin Shi, the ancients divided a day into 12 hours, and one hour is equivalent to two hours now. Take twelve records, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

The time is from 23: 00 to 1: 00, two hours per hour, and so on. The time in Yin Shi is from 3: 00 to 5: 00.

The year/month/day/hour when a person was born adds up to the date of birth.
