"I only have a .zip file"

Google Calendar exports a .zip that contains one or more .ics files.

Fix:

  1. Unzip the file.
  2. Import the .ics files inside.

See: Import from Google Calendar

"This looks like a calendar invite (METHOD:REQUEST)"

Some .ics files are meeting invites, not full calendar exports.

NimbleCal imports invites one-at-a-time so you can review the event and choose:

  • Accept
  • Tentative
  • Decline

Fix:

  • Import that invite .ics file by itself (not alongside other .ics files).

Note: No email or iTIP reply is sent in this version. Accepting only updates your local copy.

"I imported the same calendar twice and now I have duplicates"

Fix:

  • Import each calendar export once.
  • If you need to retry an import, consider importing into a new calendar so duplicates are contained.

"My times look shifted"

This is usually a timezone mismatch between the exported calendar and your settings.

Fix:

  • Check your NimbleCal timezone setting.
  • If the exported .ics includes a timezone, make sure your event is anchored to the correct one.

See: Time zones

"Some items did not import"

NimbleCal focuses on calendar events (VEVENT). Some calendar exports include tasks (VTODO), which may be skipped.
