The term sun column or time column

The sun column is one of the four columns, which is a method used by numerologists to infer fate. The sun column means that the trunk and branches of the lunar calendar represent the date of a person's birth, and the trunk and branches record one day every 60 days. Because the month is different from the leap year, it is necessary to find the sun column. In numerology, from midnight to midnight clockwise, twelve hours are a day, and each hour accounts for two hours. The dividing line between day and day is midnight. Before eleven o'clock is the last day of Shihai, and after eleven o'clock is the next day.

The time column represents the time when a person was born with branches. An hour spans two hours in the lunar calendar and twelve hours in a day. To get the correct birth time, it is most accurate to measure it with a sundial instrument during the day. When the clock time is the artificial average time and the regional standard, it is necessary to calculate the apparent solar time difference according to the solar terms and the local longitude difference according to the birthplace, so as to get the real astronomical birth time.
