We should agree on "event" meaning first of all. If we have a theater show called "my show" with 20 repetition, which is the "event"? From my point of view the event is "my show". With a good database normalization I should enter my show's name, actors name, category, calendar and so on in a event table, and repetition venue date and time in a repetition_venue_date_time table.
"Event details" menu item type should then points to event.ev_id, "Event repetition" menu item type should be date_range pointing to repetition_venue_date_time.ev_id,event_date and "Event date" should point to repetition_venue_date_time.ev_id,record_id single record. "ev_id" should be the main key to "join" all database tables.
Don't get me wrong, this is not a criticism, just sharing my point of view.
