Does a few minutes difference in birthdays affect fortune telling?

The so-called hour is the sunshine angle within the latitude and longitude of your birthplace. There are calls for immediate results. That's what it means. Because the rotation of the earth around the sun is neither parallel nor round, it is impossible to be accurate to minutes every year. The time from one year to the next is not that time at all. Beijing time is completely unreliable. So ordinary dishes can't be used to see eight characters at all. As long as the birthday time coincides with the local sunshine time. Don't just hit the intersection with your back. In addition, we should pay attention to the intersection of solar terms.
