Can the current wedding auspicious day be based on the legal marriage registration date? Or should it be based on the day of the wine?

The so-called auspicious wedding day is an auspicious day in folk wedding customs, which refers to the wedding day. There were six procedures for marriage in ancient times, but I can't remember them clearly, hehe! This date has something to do with superstition of Yin and Yang, but it has nothing to do with the law.

The date of marriage registration is the date when both parties go to the marriage registration office for marriage registration. This date has legal effect and is the basis for dividing the duration of marriage relationship in law.
