How do you recover deleted Calendar events on a Mac?

By Kayabyte · Last updated 2 November 2026

To recover deleted Calendar events on a Mac, try Edit, Undo straight away, check that the calendar is still ticked in the sidebar, and restore a dated archive from iCloud.com (Account Settings, Data Recovery, Restore Calendars and Reminders). If the events are older than that, they are in a Time Machine or iPhone backup. NoteRescue lists the events your backups hold that you no longer have and writes them as .ics files for Calendar’s own import.

Step 1: undo, and check the sidebar

Choose Edit, Undo in Calendar if it was a moment ago. Then show the calendar list (Calendar, Show Calendar List) and tick every calendar: a calendar that is unticked looks like missing events. Check Calendar, Settings, Accounts too, in case an account was turned off.

Step 2: check other devices before they sync

A deletion syncs everywhere. If an iPhone or iPad was offline, it may still show the events; open Calendar there and note the details before it goes online.

Step 3: restore a calendar archive from iCloud.com

  1. On iCloud.com open Account Settings and find Data Recovery.
  2. Choose Restore Calendars and Reminders and pick an archive from before the loss.
  3. Restore it. Apple archives your current calendars first, but the restore replaces them on every device, so note anything you added since.

Step 4: use a backup

Time Machine keeps your calendar data in your user Library. On the macOS 26 virtual Mac we tested, Calendar kept it in ~/Library/Group Containers/group.com.apple.calendar. Restoring that folder by hand swaps your whole calendar and iCloud may override it, so quit Calendar, make a safety copy first and keep Wi-Fi off while you copy events out. For the details of the swap method, see restore Calendar events from Time Machine.

A faster way: NoteRescue

NoteRescue scans Time Machine snapshots and iPhone backups, compares the events with Calendar today and lists each as missing or changed. The scan is free.

Steps with NoteRescue

  1. Open NoteRescue, allow Full Disk Access and press Scan.
  2. Open the Calendar and Reminders row, filter to Missing and select the events.
  3. Choose a folder and recover. In Calendar choose File, New Calendar and name it “Recovered”. Click Open in Calendar, choose “Recovered” in the window Calendar shows and click OK. Calendar asks for a destination for each event, so with many events expect to repeat that.

Events come back without sending invitations; attendees are listed in the event’s description. Calendar and Reminders is USD 19.99, All apps USD 39.99; one item is free as a proof. Download NoteRescue
