Does the eight-character fortune-telling use solar time _ Does the eight-character fortune-telling use solar time?

Do you use the sun time or Beijing time to calculate the horoscope? In ancient times, there was no obvious solar time or Beijing time. How did the ancients set the time? Do you only watch the local sunshine?

To be precise, it is the sun time.

Namely: apparent solar time = average solar time+true average solar time difference. When students are born, they must calculate the local average solar time according to their birthplace, and then calculate the apparent solar time according to the average solar time. He can't simply follow Beijing time to see the sun time, which just means setting the time according to the actual position of the sun.

For example, the sun is overhead, which was called noon in ancient times. That is 12 or so. Beijing time is 12, and the sun is over Beijing, but for Xinjiang, the sun at 12 is still in the early morning. If you were born in Xinjiang at 12 Beijing time, you can't calculate it according to this 12 point, and you must convert it into apparent solar time, which is the time corresponding to the real position of the sun. For example, it may be around 8 o'clock, so it should be calculated according to the time of day rather than noon. The date of birth we usually say is Beijing time in the East Eighth District, not the real local time of our birthplace. Therefore, we must convert it into the actual time determined according to the relationship between the sun. Otherwise, it is sunny noon in Beijing, and the United States on the back of the earth may be dark at midnight. We can't use Beijing noon to give it to American friends, can we?

Therefore, the place of birth and the time of birth can be calculated by the latitude and longitude of the place of birth depending on the sun.
