Google Calendar Two-Way Sync¶
Easily add, edit, and delete events from your private Google Calendar directly in Obsidian using OAuth 2.0 authentication.
Verified Integration
Full Calendar Remastered is an officially verified Google integration. You can now connect your accounts directly without creating your own Google Cloud credentials.
Calendars automatically refresh every 5 minutes. To manually refresh calendars, run the FCR Command: refresh calendars or use the command Full Calendar: Revalidate remote calendars.
Power Up with Categories
Google Calendar events fully support Advanced Categories. Use a title like Personal - Doctor to automatically apply your "Personal" color and styling.
Quick Start: Connecting Your Account¶
- Open Full Calendar Settings → Calendar Sources.
- Click Add Source and select Google Calendar.
- Click Login with Google. This will open your default browser.
- Follow the standard Google sign-in flow.
- Once authorized, select the specific calendars you want to display in Obsidian.
Advanced: Custom Google Cloud Credentials (Optional)¶
If you prefer to maintain your own OAuth Client ID and Secret for privacy or development reasons, you can enable Custom Credentials in the API and Security Settings.

Feature Notes¶
- Two-Way Sync: Changes made in Obsidian (create, edit, delete) are instantly reflected in Google Calendar.
- Recurring Events: Supports exceptions and cancellations. Deleting a single instance in a series creates a proper "cancelled" instance in the Google API.
- Timezone Management: Events are normalized to your Display Timezone while respecting the original source timezone for recurrence rules.
- Event Linked Notes: Keep rich local meeting notes or agendas connected directly to remote Google Calendar events with automated template population. Name-based mode reuses the exact sanitized title file; deadline-based mode can keep recurring occurrences separate. See the Event Linked Notes Guide for details.
- Mobile Support: On iOS/Android, the login flow opens a blank tab first to bypass popup blockers. Ensure popups are allowed for Obsidian.
Troubleshooting & Manual Authorization¶
- Manual Authorization: See the Central Troubleshooting Guide for help with OAuth redirects and manual copy-paste login.
- Android and iOS Authentication Workaround: For step-by-step instructions on authenticating Google Calendar/Tasks on mobile devices using vault synchronization, see Mobile Authentication Workaround.
