A Repeating / Recurring Event will have “Multiple Dates Available” text appended to the its start or end date whereas a Simple event will simply have a start and end date.

You might not be able to see guests in the Guests tab, as you may have edited the occurrences of your event. When you edit the occurrences of your event, then new occurrences are created and guests associated with the previous occurrences automatically leave them. You will see guests in your event after members join new occurrences of your event.

If your event is a recurring event with guests in it, then you will not be able to edit your start date. But you can choose to extend the event’s duration by increasing the End Date. You can only edit the start date of your recurring event until no guests have joined it.

A repeating / recurring event is an event that repeat over a period of time like daily, weekly, monthly, or on specific dates. Recurring / repeating events will save time and effort that event owners spent in creating multiple separate events and it also let’s them easily change all occurrences of their events in the series at once.
