External calendar IN nextcloud agenda via CalDAV


Is it possible to connect via CalDAV an external calendar IN nextcloud agenda ?


It’s not via CalDAV but you can add any public calendar that provides an .ics URL by « Adding a subscription »

Many thanks for your return … I know it but it’s not my purpose since i want synchronisation.
So my concern is CalDAV

So, no, it’s not possible (and that would be a hard thing to have).

Why it would be a hard thing to have ?

I meant to develop. Handling credentials for the external CalDAV calendar for instance.
