Yes, it works OK, but (as I said) it uses the underlying evolution
server which means that for me it isn't ideal. In particular if you
add, change or remove an event it *isn't* written to the calendar
file (~//.local/share/evolution/calendar/system/calendar.ics) at once.
In fact it isn't written for a *long* time and I can't work out what
decides it to write.  Thus I can't synchronise that file across a
couple of systems and expect it to work.

If there was a good explanation of how gnome-calendar manages files
and what things like "synchronize calendars" actually do it would
possibly make it more useful.
