I am trying to slowly peel away from Google and my next task is Google Calendar. I currently have a couple shared calendars with other people and I'm not going to be able to break them free from Google quite yet. I have a next cloud server I was hoping to set up to be my primary source but I need to be able to interact with the shared calendars as well. Can I create a group calendar and have other persons, Google Calendar sync to it?

I'm not married to Next Cloud. It was just what I have available. I can do a different setup if that would work better.

Any advice would be greatly appreciated.

TIA
