Does CalDAV have to go to an internet server or can it be self-contained on a local PC?

I'm attempting to set up software on a PC which uses CalDAV for scheduling. I found it very easy to create a CalDAV calendar with Thunderbird/Lightning. However, this PC is not allowed on the internet. Is there a way to publish CalDAV internally (self-contained to the PC) so that the software can sync to the calendar?

Chosen solution

if you have cladav server software installed yes. If not, no.

Some caldav server implementations you could use are listed here. https://devguide.calconnect.org/CalDAV/Server-Implementations/

Note that as your local machine is unlikely to have DNS or a "name" you can refer to it as 127.0.0.1 instead of the normal domain names as that IP address is what is called your loopback address ie your computer.

See for more information on loopback and localhost https://en.wikipedia.org/wiki/Localhost
