If a concert begins at 2:30 what time would it end? I can’t find an answer anywhere and need to plan for a sitter.

Yeah, it really depends on what kind of concert it is. Festivals can go on until midnight. Others arenyour typical 4 hour shows when you account for opening bands.

If it's a festival than maybe 12pm. If it's a weekday they have to be done by 11-11:30pm. Weekends go later
