Import or export calendars

To share or back up a calendar that’s in the On My Mac section of the calendar list, you can export the calendar’s events, then import them into another calendar or to another computer.

If you use a calendar account, such as iCloud or Exchange, you don’t need to export and import its calendars to back them up or have them appear on your other devices. The account calendars are stored on the calendar service provider’s servers, and are automatically updated on all your devices set up for the same calendar account.
