Trello Calendar Not Syncing With Google Calendar
Workaround available Web, Google Calendar Updated October 21, 2026
Quick answer
The Calendar Power-Up iCal feed is pulled by Google Calendar, which refreshes subscribed calendars roughly once a day. Delays are expected; regenerate the feed link if it never updates.
Most likely fix: Wait for Google's refresh.
Symptoms
New or changed due dates don't appear in Google Calendar, deleted cards still show up, checklist due dates missing.
Why it happens
- Google Calendar refreshes subscribed iCal feeds only about once per day
- Old or disabled feed URL
- Calendar Power-Up sync not enabled
- Cards without due dates
How to fix it
Try these in order — the most common fix is first.
1. Wait for Google's refresh
- Google Calendar controls how often it pulls the feed — expect up to ~24 hours
2. Regenerate the iCal link
- In the board, open the Calendar Power-Up settings and copy a fresh iCal feed URL
- Remove the old calendar in Google Calendar (Other calendars) and add the new URL via From URL
3. Clear cache and retry
- Clear browser cache/cookies and re-open the Calendar Power-Up settings
4. Use a third-party sync Power-Up
- Users try services like Cronofy for faster two-way sync, with mixed results
