Is there a scientific basis for birthdays?

Because each of us was born at a different time. And our older generation of immortals, they made a statistics on people born at this time. They will classify these people according to the ordinary date of birth and make statistics on their lives, thus establishing a set of big data.

In fact, today's birthday is like our big data. He put all people of the same type on the same birthday, and then described their fate in words according to their characteristics.

In this way, when giving instructions to future generations about the survival of the eight characters, it is only necessary to re-list the previously sorted text materials from these databases.

This is also the reason why there are so many computer fortune tellers in today's society. They input all these data into the computer, and when we input our birthdays, the computer will automatically bring up the relevant data.
