Import or export calendars on Mac
You can import and export calendars and calendar events as a way to share calendars with other users, or save copies of calendars and calendar events to your Mac. If you’re not using a calendar account, such as iCloud or Exchange, importing and exporting can also be used to back up, restore, or transfer calendars in the On My Mac section of your calendar list.
Keep in mind that if you’re using a calendar account, such as iCloud or Exchange, your calendars are all automatically stored on the provider’s servers. These servers regularly update your calendars and give you access to them across all your devices. This allows you to avoid having to manually back up and restore your calendars or manually transfer these calendars to other devices.
Export a calendar’s events
You can export an individual calendar’s events to a calendar (.ics) file. You can use this method to share a calendar’s events with other users, back up calendars in the On My Mac section of your calendar list, or import a calendar’s events to another calendar or device later.

on your Mac.Click the calendar’s name in the calendar list.
If you don’t see the calendar list on the left, choose View > Show Calendar List.
Choose File > Export > Export.
Choose where to save it, then click Export.
The events can be exported to a calendar (.ics) file only.
Export all calendars
You can export all your calendars at once to a calendar archive (.icbu) file. You can use this method to back up all the calendars in the On My Mac section of your calendar list at once, share your calendars with other users, or import your calendars to another device later.

Import events from a calendar file
