Eight characters for fortune telling

Birth calculation originated from the Book of Changes, which is a method of killing people by observing the relationship between birth time and fate. The calculation of eight characters is based on the "year, month, day and hour" of a person's birth. The year, month and day here are four pillars in the eight characters, each pillar is divided into two words, and the four pillars are multiplied by two, making a total of eight words. So eight-character calculation is also called "four-column eight-character calculation".

Birth is the year, month, day and hour of heavenly stems and earthly branches. Add up to eight words. 10 heavenly stems: A, B, D, E, G, Ji, Ji 12 earthly branches: Zi Chou Mao Yinchen has arrived in Xu Hai, Shen You at noon. When you record the year, month, day and time of a person's birth with sixty flowers, there are four pairs of heavenly stems and earthly branches, with eight words in all, which is the person's 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"
