Subscribe to local calendar as ics/caldav

Is there a way to expose the local Home Assistant calendars as ics/caldav?
I’ve found only ways to integrate external calendars, but I want to do the opposite.

Usecase: we track chorse in Home Assistant and I show them on the local calendar and want to expose them on calendars on all devices.


I am also much interested in such a feature. My use case is that I have imported mine and my partners calendar to HA. Which I now want to expose and share with my extended family along with some local HA calendars.

I want the sharing to be as simple as possible, for example with one single URL to get all calendars.
