What day of the week is best for a Bar/Bat Mitzvah?

Technically Bar/Bat Mitzvahs can be held on any day that the Torah is read. This includes Saturday morning/afternoon, Mondays, Thursdays, and some Sundays. Although, most people choose to have their service on Saturday since more guests will be able to attend and it’s the best day to throw a party. Not to mention the fact that it is the holiest day of the week for Jews.
