Is there any basis for the statement of ancient birth date?

I think there is a certain basis for the ancient saying of birth. In ancient times, because science was underdeveloped, people created many things through their own clever labor. Then, as a fortune-telling method, birth can reasonably use the integration of heavenly stems and earthly branches to calculate a person's fate from the date of birth. Then, with the passage of time, many scientists have made textual research on this and got some very important theories from it.

? In ancient times, time was recorded by some methods, such as the sun and the hourglass. Based on this, people's birth has a certain accurate time. Then, heavenly stems and earthly branches of that year is attached, so that the date of birth and the specific time will be recorded. Fortune tellers usually guess a person's fate by birth, which was very popular in ancient times. The daughters and young masters of rich families will also infer their birth dates in this way, so as to predict the possible bad luck in the future, and also confirm what will happen in the future through the calculation of birth dates. This shows that it can only be used by people after it has a certain scientific basis.

Although many people in today's society will think that the ancient birth statement is a very superstitious view, it does not mean that it is groundless. I believe many people will think that fate is in their own hands and will not believe the eight-character speculation. But I don't know, birthdates' statement is the crystallization of the labor wisdom created by the ancient working people, and it is displayed according to certain science and some special ways.

For birthdates, it will be inferred by combining the specific time when a person was born on the same day and the various changes of Yin-Yang and Five Elements. There are many things to consider. From a philosophical point of view, it is not idealism, but materialism, and there is a certain dialectical thought in it. So I think there is some basis for birthdates' statement.
