How to delete all calendar events?

When you delete a calendar, all events in that calendar will be deleted.

If you are viewing the events in the Calendar.app on a Mac, it will be as simple as selecting the calendar in the sidebar of the Calendar app, ctrl-clicking it, then selecting "Delete".

So, import your new events to a separate new iCloud calendar, and when you want to delete all of them, delete the calendar. Create the calendar new for the next batch of events.

You can manually delete an event from the main calendar view, or you can set Calendar preferences to hide past events automatically.

To delete an event, click the event to select it and press the Delete or Backspace key.

If you invited anyone to the event or if it belongs to a shared calendar, a window appears giving you the option to notify participants of the cancelation.

To automatically hide past events, click the Action pop-up menu in the sidebar, then choose Preferences. In the Advanced pane, select “Hide events n-days after they’ve passed,” then enter the number of days.

If you accidentally deleted iCloud calendars or events, you can use iCloud.com to restore them, together with your reminders, from an earlier version that was automatically archived in iCloud.

Thanks, but this won't work because what I would have to do is go to all of my mobile devices (4) as well as my laptop, delete the calendar from all 5 devices, create a new calendar, populate the new calendar, and add the new calendar to the remaining 4 devices.

Why is that? When I create a new iCloud calendar on my Mac, it will automatically appear on all my devices that are syncing with iCloud, and when I delete this iCloud calendar on my Mac, it will be deleted from all my devices.

That's why I want a way to simply "empty" my current calendar and then fill it back up. As I said, this is trivial when using Google Calendar, and it's frustrating that Apple doesn't seem to offer similar functionality.

Why do you want to switch to using iCloud for your calendar account? Is there something that it provides that Google doesn't? That part isn't clear to me.

You can sync your Google calendar to your Apple calendar and then just continue deleting through the Google interface. Of, just keep using Google. It will sync to all of your Apple devices.
