For various reasons, you might end up wanting to clear all events from a calendar in your account. For example, you might have added events to your default calendar that you now want to move to a calendar that you created. Or, you might have imported events more than once and ended up with duplicates.
The most efficient way to clear large numbers of events at one time is to use the bulk Remove, Delete, or Move options that you access by setting your calendar to .
Alternatively, you can cancel events. In this case, the events remain on the displayed calendar, but are labelled Cancelled. See How to cancel and uncancel events.
Note For Publisher accounts only, you can also mark events as Private to clear them from the public calendar. See Private events.
Important In the List view, you can apply bulk actions on the events currently displayed. The view is usually limited to 100 events per page. So, after applying a bulk action, you may need to cycle forward to display (and then apply bulk actions to) your future events.
