The video below demonstrates how to create a recurring event which repeats every week.
Repeating classes (events) are special items in your calendar that occur regularly (daily, weekly, monthly...) at a certain time. Each recurring event repeats multiple times and has several occurrences. All occurrences are accessible through the same link. Giving access to a recurring event gives access to all instances in the series.
The example shows how to create a weekly event (which occurs once a week). Similarly you can create daily, monthly or even annual events.
