Event

A series (or set) of activities can be created for two reasons. Firstly, to create an entire series of activities at once for a longer period, making it easy to fill, for example, half a year. This could be used for a swimming lesson or fitness class that always takes place on the same day/time. Another reason to create a series is when a course consists of multiple days.

Both are series but reserved differently. You might want to create a fitness class as a series but allow it to be booked per individual session, whereas a multi-day course, possibly with an exam, should be bookable as a complete set. This is, of course, possible.

To create a series of activities, first create a single activity.
Once the single activity is fully configured (name, description, image, status, etc.), you will find a 'create recurring activity' button in the action menu on the activity’s dashboard.

Next, choose whether the activity should recur daily, weekly, monthly, or yearly. Different settings are available for each period to create the series. For example, you can create a daily series that schedules an activity every 3 days until the end date, a weekly series every Monday, Tuesday, and Thursday until the end date, or a monthly series on the 2nd Wednesday of odd months, etc. Then select an end date for the series to stop and save it.

At this point, the series is saved per activity and can therefore be reserved per activity. It is possible to change the date of individual activities while they remain part of the series.
As mentioned, it is also possible to allow a series of activities to be reserved. To do this, click on 'Show series details' and select the option 'Book for the entire series' under 'Series type'.
