I installed and have a running WebDAV server (Davical) and now would like to publish my calendar from Thunderbird (Lightning), as advertised here: https://support.mozilla.org/en-US/kb/exporting-and-sharing-a-calendar (under "Steps when Running Lightning").
However, I don’t know my WebDAV URL. Quite probably I don’t really understand how it is supposed to work. Do I have to create a new calendar on the server first? Or how is publishing meant to work?
In the end, I’d like to have a regularly synced iCal URL on my WebDAV server, so I can access it through Google Calendar (as Google Calendar apparently does not work with CalDAV).
