NimbleCal
Last reviewed Mar 18, 2026

Apple Calendar exports calendars in the standard iCalendar format (.ics), which NimbleCal can import.

Privacy note
The exported ICS file is plain text while it sits in Downloads, cloud storage, email, or shared folders. After you import it, the events stored in NimbleCal use the app's normal end-to-end encryption.

Step 1: Export from Apple Calendar on macOS

  1. Open the Calendar app on your Mac.
  2. In the sidebar, click the calendar you want to export.
  3. In the menu bar, click File → Export → Export
  4. Save the .ics file.
Tip
Apple Calendar exports one calendar at a time. Repeat these steps for each calendar you want to move.

Step 2: Import into NimbleCal

  1. In NimbleCal, in the left sidebar under My Calendars, click the + menu.
  2. Choose Import calendar.
  3. Click Browse files.
  4. Select the .ics file you exported.
  5. Choose where to import:
    • + New to create a new calendar for the import (recommended), or
    • Existing to add events into an existing calendar.
  6. Click Import events.
Free plan note
Creating a new calendar counts toward your plan limit. If you're on Free and already have your 1 calendar, import into an existing calendar (or upgrade to Plus for unlimited calendars).
