Team/Group Planning Calendar

Does Nextcloud provide a group/team (planning) calendar?

As far as I know, it is not available. Would there be more people interested to have a group/team based (planning) calendar in Nextcloud?

It would be very nice when the team calendar would use the agenda data, that is already present for a user in Nextcloud. But only for the bigger/longer events, like a business trip, illness, a day off, multiple days off, a holiday and the like.

On the other hand the team planner should show duty services, like: for out of office hours, hotline, project assignments, etc. These should show up in the userโ€™s agenda.

A very nice example is available at https://teamup.com -> https://www.teamup.com/live-demo/ I especially like the โ€˜date rangeโ€™, with the possibility to provide the number of days and weeks that should be shown. Together with the zoom factor makes it very flexible.

Screenshot:

To make it an effective tool, user data should only be provided once while a user could be part of multiple teams.

Would it be possible to include a teamplanner in Nextcloud (based on / using already available apps, such as the calendar, circles app, and the flow app or whatever is needed).

Their is no feuater called that. But you cann use a new user make a new calender, share it, and give read and write permission to everyone included.
The Calender object can be used as normal from every user.
