How to calculate date of birth?

Birthday, or eight characters, is actually another way of saying the four pillars of Zhouyi. Four pillars refer to the time when a person was born, that is, year, month, day and hour. When people use "heavenly stem" and "earthly branch" to represent year, month, day and hour respectively, such as Jiazi Year, Shen Bingyue, Xin Ugly Day and Renyin Time. There are two words in each column and eight characters in four columns, so fortune telling is also called "measuring eight characters" According to the relationship between yin and yang attributes and the five elements of heaven and earth, it is inferred that human body is responsible and blessed. However, what I want to talk about here is not how to "measure eight characters", but how to calculate eight characters.

Four-column eight-character arrangement

Four pillars refer to the year, month, day and time when a person was born. Four-column arrangement refers to finding a person's date of birth. It is mainly divided into four steps.

Chronological column

Chronicle, that is, the year when a person was born, is represented by branches. Note that the dividing line between last year and next year is based on the intersection time of beginning of spring, not on the first day of the first month. For example, if someone was born at 22: 00 on February 4, 2000 in the solar calendar, because the lunar calendar was handed over to beginning of spring in 2000 at 20: 32 on February 4, 2000, his chronological column is 2000.

Moon column

Moon column, that is, the festival when a person is born, is represented by stem and branch. Note that the branches and branches of the month are not divided by the first day of each month in the lunar calendar, but by festivals. The festival before the handover is the festival of last month, and the festival after the handover is the festival of next month.
