Eight characters: Birthday is the date when a person was born. These eight words have a place in Chinese folk beliefs. The stems and branches of a year form a column of years, the stems and branches of a month form a column of months, the stems and branches of a day form a column of days, and the stems and branches of a year form a column of times. A total of four pillars, four stems and four branches, a total of eight words, so it is also called four pillars and eight characters.
In the application, the annual column or the moon column is the main life, but most of them are based on the daily stem of the daily column. The annual stem represents ancestors, the monthly stem represents parents, and the daily branch represents oneself and brothers and sisters (I am male, and the daily stem represents brothers and sisters; I am a woman, my sister and brother, and I am the heir.
Also take the life palace, fetus, Universiade, Universiade, fleeting time, and cooperate with the five elements of old age and moon order to restrain blame.
Extended data:
China has used heavenly stems and earthly branches to accurately record years, months, days and hours since ancient times. It consists of eight branches: annual stem, annual branch, monthly stem, monthly branch, daily stem, daily branch, hourly stem and hourly branch.
The combination of year, month, day and hour is called "column", which forms "year column", "moon column", "sun column" and "time column", so the eight characters are also called "four columns" or "four columns and eight characters".
To learn eight characters, you must be familiar with the dry calendar. Every year, beginning of spring is the beginning of the New Year, and beginning of spring shocks silver moon (like the first month of the lunar calendar), with the "Festival" moment as the beginning of the month and the "Qi" last moment as the end of the month; Then calculate the heavenly stems and earthly branches of month, day and hour in turn.
Because the horoscope only reflects the relative angular position of the earth and the sun, the conversion of the horoscope formula of time needs to refer to many factors, including average solar time, sidereal time, average solar time difference, time zone and daylight saving time. This conversion algorithm is more accurate, but it is also complicated, mostly with the help of computer-aided calculation, usually with a perpetual calendar, and the formula is simple.
