Can I create a master calendar that syncs multiple databases?

Yes, it is possible to create a master calendar on Notion that syncs multiple external calendars or databases to have every task and event in one place.

However, keep in mind that it's not possible to sync multiple Notion databases in the same automation. You will need to create a second automation to sync another database.

Example

Here's a video that we made to show how we can:

1. Create a 2-way sync Google Calendar with the Ultimate Brain template

2. Create multiple syncs

If you follow these instructions, you can set several automations in place that ultimately connect to a master calendar of your choice. In this case, we have used the Ultimate Brain template, but you could use any other custom database of your choice.
