How to determine the fortune-telling time?

The ancient time was roughly divided into twelve hours, which is basically equivalent to two hours in the current 24 hours. Four-pillar fatwa originated in China, in the Central Plains. At that time, the problems of remote ethnic groups were not considered. Although there is no unified concept of Beijing time in ancient times, it is more accurate to calculate with the birthplace as the reference.

In fact, time unification is a mandatory concept, in order to unify. A person's birth time is best calculated according to the local birth time. China has a large span between the east and the west. According to the current rules, it spans at least two or three time zones. According to the ancient system, the difference is almost an hour or two. Fortunately, the ancient masters were very meticulous, and they described the performance of everything in the world at every moment for reference. For example, although the sunrise in a certain season varies from place to place, according to this standard, what time is determined, not necessarily Beijing time.
