Hey amandaveeenhuis,
Right now the way Events Calendar PRO handles recurring events, yes, you would have to enter Sunday separately from the rest. We considered recurring events has having a regular structure when we built it. However, our users, like yourself, have made it clear that the world is not so neat and we are actively working on what I’ll call “irregular recurrence” for events. So while you might need to enter this as essentially two separate events at the current time, that may change at some point in an upcoming release.
Does that make sense?
