Does the wedding reception at home have to be on Sunday? What if you don't have time on Sunday when you get married?

I haven't heard that the wedding reception must be arranged on Sunday, because auspicious days are not arranged on a weekly basis, but according to the lunar calendar. Since ancient times, auspicious days have been chosen according to the monthly cycle. Now everyone is willing to choose two days, which means in pairs. Of course, it is better to catch up on Sunday, because there is no need for everyone to take time off!
