What are human birthdates made of?

summarizing birthdates or the eight characters is actually another way of saying the four pillars in Zhouyi. Four pillars refer to the time when a person was born, that is, year, month, day and hour. When people use the word "heavenly stems" and "earthly branches" to represent the year, month, day and time respectively, such as the year of Jiazi, the month of Bingshen, the ugly day and the time of Renyin, etc., it contains the basic state of celestial movement when a person is born. Each column has two characters and four columns have eight characters, so fortune telling is also called "measuring eight characters". According to the relationship between the attributes of yin and yang and the five elements of heaven and earth, it is inferred that people's body is blamed and blessed. [Edit this paragraph] It is always said that to get the correct birth time, the sundial instrument is the most accurate measurement during the day. When the clock time is the artificial average time and regional standard, we must calculate the "apparent solar time difference" according to the solar terms (solar ecliptic) and the "local longitude time difference" according to the place of birth, so as to get the real astronomical time of birth.

among the eight characters, the dry branch of the year and the dry branch of the day are continuous and real; The branches of the month and the time are calculated according to the branches of the year and the day, which can be said to be virtual.

birthdates can only reflect the date of a person's birth at most, so it is not an exaggeration to record the time. Some people use birthdates to tell their fortune, which is very unreliable. Because a person's fate is influenced by many conditions, in addition to the weather, there are also restrictions on the region where he grew up and the crowd. Coupled with the difference in opportunities, how much can the influence of the time of birth account for? [Edit this paragraph] Arrange four columns with eight characters

Four columns to refer to the year, month, day and hour of a person's birth. Four-poster arrangement refers to finding a person's birthdates. It is mainly divided into four steps.

chronological column

chronological column, that is, the year when a person was born is represented by branches. Note that the dividing line between the previous year and the next year is based on the intersection time of beginning of spring, not on the first day of the first month. For example, someone was born at 22: 17 on February 4th, 2 in the solar calendar. Since the lunar calendar was handed over to beginning of spring at 2: 32 on February 4th, 2 in the solar calendar, this person's year column is the year of 2, not the year of 1999.

the general algorithm of chronology: the numbers from A to Deck of the heavenly stems correspond to 4, 5, 6, 7, 8, 9, , 1, 2, 3 respectively, while those from the earthly branches to Hai correspond to 4, 5, 6, 7, 8, 9, 1, 11, , 1, 2, 3 respectively. The stem and branch algorithm of a year takes the last digit as the heavenly stem, and the ground branch is the remainder of the year divided by 12. Take 1978 as an example, the last digit of 1978 is 8, the heavenly stems are E, the remainder of 1978 divided by 12 is 1, and the corresponding branch is noon, so 1978 is the year of Wuwu.

Simple algorithm of chronology: The premise of this method is to know which zodiac year the year is, which is generally used for quick calculation in recent years. Take 29 as an example. As we all know, 29 is the Year of the Ox. Since it is a cow, the earthly branches are of course ugly, and the last 9 in 29 corresponds to heaven, so 29 is the year of ugliness.

Moon column

Moon column, that is to say, the branches and branches indicate the festivals where people are born. Pay attention to the fact that the monthly branch is not divided by the first day of each month in the lunar calendar, but by festivals. Before the handover, it is the festival of last month, and after the handover, it is the festival of next month.

January (Yinyue) is from beginning of spring to Jing Zhe, February (Uzuki) is from Jing Zhe to Qingming, March (Chenyue) is from Qingming to long summer, April (Mitsuki) is from long summer to Mangzhong, May (noon) is from Mangzhong to Xiaoshu, June (unfinished) is from Xiaoshu to beginning of autumn, and July (shenyue) is from beginning of autumn. Refer to the first chart of the month from the beginning of the year to push the monthly trunk and branch from the day of the year. If the annual stem is a or oneself, the stem of the first month of that year is C-Yin; If the annual stem is B or G, the stem of the first month of that year is Wuyin; If the annual stem is C or Xin, the stem of the first month of that year is Geng Yin; If the annual stem is Ding or Ren, the stem of the first month of that year is Ren Yin; If the annual stem is E or decyl, the stem of the first month of that year is Jiayin.

Japanese column

Since February, the third year of Lu Yingong (722 BC), it has been a day since then, and the records of the main branches and branches in China have never stopped. This is the single longest method of recording the day known to human society so far.

A solar column is the day when a person is born on behalf of the trunk and branch of the lunar calendar. The calendar of the main branch records every 6 days. Due to the different months and leap years, the main branch needs to find a perpetual calendar (an online perpetual calendar website: site.baidu.com/list/wannianli.htm).

In addition, the dividing line between day and day is divided by hours, that is, before eleven o'clock, it is the hour of the previous day, and after eleven o'clock, it is the hour of the next day. Don't think that midnight is the dividing point of the day.

chronological column

chronological column, with branches indicating the time of birth. An hour spans two hours, so there are twelve hours in a day.

midnight: 23: -1: a.m. Ugly hour: 1: -3: a.m.

Yinshi: 3: -5: a.m. Maoshi: 5: -7: a.m.

Chenshi: 7: a.m.-9: a.m.-11: a.m.

It is pushed by the sun. Click to see clearly

noon: 11: -13: pm: 13: -15: pm

application time: 15: -17: pm: 17: -19: pm

short time: 19: -21: pm: 21: -. If the trunk of the day is Jia or himself, the trunk of the day is Jia; If the trunk of the day is B or G, the trunk of the day is C; If the trunk of the day is C or Xin, the trunk of the day is Wuzi; If the trunk of the day is Ding or Ren, the trunk of the day is Geng Zi; If the stem of the day is E or decyl, the stem of the day is nonnut. [Edit this paragraph] Take a friend of mine as an example. My friend was born at 8 am on August 27, 1984, and August 27 is July. This year is the year of Jiazi (found in the book); According to the rhyme of the standing moon column, we can know that his age is a, so his standing moon column is Renshen; Accordingly, his daily column is Guisi (found in the book); According to the rhyme of the time column, his time column knows that it is a dry day, and C matches the time, so the time column should be C. In this way, his birthdates is discharged: "Jia Zi is unwilling to apply for a place, but he is still in the past.".

Since ancient times, when A Jia started Jia Zi, the original Jia Zi of Ye Zi is the same, so it is ok to add Ye Zi.
