If a "recurring" event (for example, a weekly exercise class) has been added to the event management system, it is possible to change the times of all these events an masse if necessary.
1. Open the event from the event management system whose start/end times you want to modify. The time can be corrected for other events as well through the "Performances" tab as shown in the picture.
4. After saving, a window like the one shown in the picture opens. Here you can choose if you want to update the changes to other events as well.
