Notion Google Calendar Two-Way Sync: Setup Guide

Notion’s own help center says database entries can be viewed in Notion Calendar but not pushed into Google Calendar itself. Notion to Calendar closes that gap with two delivery paths: two-way direct sync and a universal iCal subscription for Free users or shared calendars.

Set up direct two-way Google Calendar sync

Direct sync uses Google’s official Calendar API and the narrow calendar.app.created permission. It creates a calendar owned by this integration and writes mapped Notion events there. It does not need permission to manage every calendar in your account.

1. Sign in at notiontocalendar.com with Notion.
2. Select the database with the dates you want in Google Calendar.
3. Choose which date property maps to event start times.
4. Connect Google from the dashboard, then open the calendar link and start direct sync.
5. Confirm the connection shows two-way sync. Older observation-only connections need two-way sync enabled before Google edits can update Notion.

Free and shareable option: use the iCal feed

Your Notion events appear as a subscribed calendar. Google chooses when to check external feeds. Premium uses a shorter server cache, which does not control when Google fetches updates.

1. From your dashboard, select the Notion calendar you want to subscribe to.
2. Click Get calendar link to generate the private .ics URL.
3. Open Google Calendar on the web (calendar.google.com).
4. Click the + next to Other calendars → From URL.
5. Paste the private .ics URL and click Add calendar.

Tips for a clean Google Calendar view

• Use filters to show only active tasks or a specific status
• Create separate feeds per project — each gets its own color in Google Calendar
• Custom event titles make dense calendars readable at a glance

Verify a change in each direction

Create a non-recurring event in Notion with a title and date. Wait for it to appear in the dedicated Google calendar, then move it to a new time in Google and check the linked Notion date. Update the title in Notion and check Google. Allow time for asynchronous processing between edits.

If you already subscribe to this database by iCal, compare the calendars first. Then hide or remove the old subscription to avoid duplicate events.

What two-way sync supports

If both apps change before synchronization, the later reliable modification time wins for supported edits. Notion takes priority for tied or uncertain times and during recovery. Direct sync is asynchronous and does not promise instant updates.

• Titles and dates on linked, non-recurring events, including all-day and multi-day dates. Use a writable Notion date property.
• Location and description edits only when the mapped Notion properties can represent them. Generated links and read-only page content must stay intact.
• Create events in Notion first. New events created only in your external calendar are not imported into Notion.
• Recurring events, attendees, meeting responses, reminders, and conferencing changes are not synchronized.
• Deleting an external event does not delete or archive its Notion page. Deleting the source event in Notion removes its mapped calendar event when processed.
