A festival is one event with a start and an end date, not three rows to repeat.
How to create it
In the editor turn on “Lasts more than one day (festival)” and pick the last day. The end date must come after the start; an event can last at most 60 days.
How it looks
Lists, page, map, widget and EPK show the range (“20 November → 22 November 2026”). The calendar file closes on the last day and the night stays “live” until then, instead of moving to past events after the first evening.
There is no automatic recurrence: a weekly residency is published one date at a time.
