How do you know the time column in birthdates? Now I look at the perpetual calendar and know that the time column will be short on the day of the month, and what is missing after reading the eight characters. Please teach me. First of all, the chronological column branches, if the birth time is between 23-1 o'clock, the chronological branch is the child, the birth time is ugly at 1-3 o'clock, the chronological branch is ugly, the 3-5 o'clock branch is the yin, the 5-7 is the Mao, the 7-9 is the Chen, the 9-11 is the Si, the 11-13 is the noon, and the 13-15 is the afternoon.

then, the time-arranging column is dry, and the time-column is dry, which is based on the combination of the day-drying (birthday-drying) and the column-ground branch.

The specific deduction algorithm is: those born on the first day or on the second day will start from Jiazi, those born on the second day will start from Bingzi, those born on the third day will start from Wuzi, those born on the fourth day will start from Gengzi, and those born on the fifth day will start from Renzi. If the child starts from Jiazi, of course, ugly will start from B ugly, and Yinshi will start from C Yin.
