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.

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.
