What is a CalDAV?
CalDAV is an Internet standard allowing a client to access scheduling information on a remote server.
What kind of calendars can I connect?
Using CalDAV credentials (account, password, url link), a user can add a variety of private calendars beyond the preset Google/Apple options. This option is intended for users whom are familiar with CalDAV, and not every client may support CalDAV syncing.
