How to calculate a person's birthday by his birthday?

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 pillars and eight tyrants? 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 columns, that is, the year when a person was born, are 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, a person was born at 22: 00 on February 4, 2000 in the solar calendar 17, and was handed over to beginning of spring at 20: 32 on February 4, 2000 in the lunar calendar, so his chronology is listed as 2000. Instead of 1999, the moon columns are arranged, that is, the branches indicate the festival when the person was born. Note that the main branch of the month is not based on the first day of the lunar calendar, but on the festival, which is the festival of last month. After the festival, it will be the festival next month.

This is by far the only longest method known to human society to record the number of days. Yangzhu refers to the day when the main branch of the lunar calendar was born. The days of tracking cadres and branches are repeated every 60 days. Because the month is different and the leap year is flat, it is necessary to find a perpetual calendar for cadres and party branches. In addition, the dividing line of a day is divided by hours, that is, before eleven o'clock, it is the last day.
