Is the year of marriage in fortune telling the time of getting a license, holding a wedding or living together?

I remember the old man talking about a wedding.

First of all, you can't get a license. The marriage certificate is only a few years old. This is of legal significance.

The old man said it was a wedding, worshiping heaven and earth, and there was a ceremony to tell God about the act of getting married.

Living together is hard to say. After all, in ancient times, it was basically a wedding before entering the bridal chamber, but it should not be a marriage without birthright.
