Problem

There isn't any way to find the pages that contain a specific calendar

Suggested Solution

Have a function/ability, REST API, or CQL to find the pages containing a specific calendar.

Why This Is Important

It's essential to know that the pages contain a specific calendar, which helps with content management and maintaining calendar notifications.

Workaround

Using macro usage can provide a list of pages containing the calendar macro.

Please note that this still requires reviewing the pages to identify the specific calendar.
