Click on the delete icon () from the calendar to delete an event. The delete icon will appear only to users who have edit permission on the event (see event ownership for more information).

Deleted items are not actually removed from the database - they are simply marked as having been deleted and become invisible. Please see the deletions article for more information. To delete large numbers of events prior to a certain date one may use the delete events dialog. You may fully remove events from the database using the clean deleted events dialog.

Un-deleting events

Users with trusted edit or higher permission may recover mistakenly deleted events using the search dialog. For these users an additional checkbox appears called 'Search deleted items...'. Checking this box will cause deleted events to be included in the results. On the results screen any previously deleted events will be displayed with the undelete icon (). Click on this icon to undelete the event.
