How to solve the eight-character fortune telling

Eight-character fortune telling is based on the year, month, day and hour of a person's birth, and according to the traditional counting method of branches and branches in China, the branches and branches at that time are discharged to form a eight-character combination. Also known as birthdays. A child was born in 2009.

The ugly year of the lunar calendar became the first two words of heavenly stems and earthly branches. So if the child is born in the first month of the lunar calendar, we can draw the conclusion that the month order of the first month is C Yin according to the method of starting the month in the previous year: "C is the first year of Jiaji". Suppose the child was born on the twentieth day of the first month, we can see that the main branch of the almanac is Geng Yin. If you were born at noon 12 o'clock, we can know that it is noon according to the ancients' saying that "B Geng C begins". In this way, a child's eight characters are discharged. Namely: Ugly Year, Bing Yinyue, Geng Yinri and Noon. In other words, the year column, the moon column, the sun column and the time column are two words. This is called four-column fortune telling, also called eight-character fortune telling.
