Is it okay for people born in the same year and the same month to get married?

Marriage has a lot to do with many aspects, but it seems to have little to do with birth.

If two people born in the same year, the same month and the same time have different values, different living habits, mismatched tempers and personalities, and are irresponsible to the family and the other party, then even if they are born in the same delivery room at the same time, it is useless and will not live well.
