How to Export Google Calendar (ICS Backup, Single Calendar, Takeout — 2026)

How to Export Google Calendar (ICS Backup, Single Calendar, Takeout — 2026)

Google CalendarExportBackupIcsHow-to

Google Calendar can export your data as ICS files — universally readable by Outlook, Apple Calendar, Thunderbird, and most other calendar tools. There’s no date-range filter and no automation built into Calendar itself, but Google Takeout fills that gap.

1. Export All Calendars You Own

The fast path. Web only.

  1. Open Google Calendar.
  2. Click the gear icon (top-right) → Settings.
  3. Left sidebar → Import & export.
  4. Under Export, click the Export button.

A file named <youraddress>@gmail.com.zip downloads. Inside: one .ics file per calendar you own (named after each calendar’s ID).

What’s not included: calendars where you only have read or write access, but not ownership. Those are read-only subscriptions and can’t be exported.

2. Export a Single Calendar

When you only need one calendar (e.g., a project calendar), don’t bother with the full ZIP.

  1. Calendar web → left sidebar → My calendars.
  2. Hover over the calendar you want.
  3. Click the three-dot Options menu.
  4. Choose Settings and sharing.
  5. Scroll to Calendar settings.
  6. Click the link Export calendar.

A single .ics file downloads.

3. What’s in the .ics File

The export includes:

  • All past and future events on that calendar.
  • Event titles, times, descriptions, locations, attendees, recurrence rules.
  • Timezone information (IANA-format identifiers).

What survives a round-trip back into Google Calendar:

  • Title, time, description, location, recurrence.

What’s lost on re-import:

  • Guests (the RSVP list).
  • Conference data (Google Meet links, dial-ins).
  • Reminders specific to the original event.
  • Attachments (referenced as Drive URLs but not embedded).

This means re-importing an export to recover from a deletion brings back events but not invitee lists. For truly safe backups of meetings with guests, use Google Takeout (section 6) and keep the source.

4. Import into Outlook

Both Outlook desktop and Outlook web accept .ics.

Outlook desktop:

  1. File → Open & Export → Import/Export.
  2. Choose Import an iCalendar (.ics) or vCalendar file (.vcs) → Next.
  3. Browse to the .ics file → Open.
  4. Choose Open as New or Import to merge with an existing calendar.

Outlook on the web:

  1. Click the calendar icon in the left sidebar.
  2. Click Add calendar → Upload from file.
  3. Browse to the .ics → choose target calendar → Import.

5. Import into Apple Calendar / iCloud

iCloud doesn’t accept .ics directly through the web UI. Import via macOS Apple Calendar — the events sync up to iCloud automatically.

  1. Open Apple Calendar on macOS.
  2. File → Import → select the .ics file.
  3. Choose the destination calendar (one of your iCloud calendars).
  4. Click OK.

The events appear immediately and sync to iPhone/iPad/web.iCloud within minutes.

6. Google Takeout (Scheduled Backups)

Native Calendar has no scheduled-export option. Google Takeout does.

  1. Go to takeout.google.com.
  2. Click Deselect all.
  3. Scroll to Calendar and tick the box.
  4. Click Next step.
  5. Pick a delivery method (download link, Drive, Dropbox, OneDrive, Box).
  6. Frequency: choose Export every 2 months for 1 year for six automated backups.
  7. File type: ZIP or TGZ.
  8. Click Create export.

Same ICS format. The advantage is the recurring schedule and the option to deliver into a backup destination automatically.

If you’re exporting because you want to keep two calendars in sync, free calendar sync does it continuously instead of as a one-shot export.

7. Subscriptions and “Other Calendars”

Calendars added under Other calendars (holidays, public ICS subscriptions, someone else’s shared calendar) cannot be exported. The Export button only walks My calendars you own.

To back up a subscription:

  1. Find the original .ics URL (Other calendars → Settings and sharing → “Public address in iCal format”).
  2. Download the .ics file from that URL directly (curl, wget, or paste the URL into a browser).

8. Outlook → Google (the Reverse)

If you’re moving from Outlook to Google Calendar:

  1. In Outlook: File → Open & Export → Import/Export → Export to a file.
  2. Choose Comma Separated Values (CSV) for individual events, or save as .ics if available.
  3. In Google Calendar: Settings → Import & export → Import.
  4. Choose the file and target calendar.
  5. Import.

Google can also import .ics files and CSV exports from Outlook.

9. Backing Up Before Deleting a Calendar

If you’re about to delete a calendar (because it’s outdated or being replaced):

  1. Export it first (section 2).
  2. Verify the .ics file opens correctly in another tool.
  3. Then delete the calendar (Settings and sharing → Remove calendar → Delete).

Once deleted, the calendar is unrecoverable past ~30 days even via Workspace admin recovery.

10. Workspace Admin Restrictions

Admins can disable export via Admin Console → Apps → Google Workspace → Calendar → “Allow users to export calendars”.

When disabled, the Export button disappears from Settings. Users must request export through the admin or use Takeout (which the admin can also disable separately).

11. Date-Range Filtering

Google does not offer a date-range filter at export. The .ics contains everything. To extract a slice:

  1. Import the full .ics into Apple Calendar or Thunderbird.
  2. Use the client’s filter or selection tools to grab events in your date range.
  3. Export those events back out.

Or use a third-party tool like iCal Import Export to filter the .ics before import.

12. Common Gotchas

  • Older Outlook installs trip on long IANA timezone IDs like America/Argentina/.... Workaround: import into Apple Calendar first, then re-export and import into Outlook.
  • Recurrence rules sometimes mis-import if the source has unusual patterns (every 3rd Tuesday of the month, etc.).
  • All-day events can shift by a day on import depending on the destination’s timezone handling.
  • Drive attachments in event descriptions appear as URLs, not embedded files.
  • The export file naming uses calendar IDs, not friendly names — c_xx...@group.calendar.google.com.ics. Rename for clarity.
