Works really well and syncs perfectly with Google calendars Rated 5 out of 5 stars

I have been using Lightning for a long time, and it works really well. I don't use any local calendars, and use two different Google Calendars via CalDAV (mine and my wife's), and then a few read only calendars subscribed via ics (things like holidays, sport fixtures etc). It's worth noting that you don't need 'Provider for Google calendars' if you're using CalDAV.

Recently Google have changed how one needs to connect to the CalDAV calendars, which for a few days stopped my system working properly. I have just changed it around, following the instructions at

https://blog.mozilla.org/calendar/2013/09/google-is-changing-the-location-url-of-their-caldav-calendars/

and everything is now working beautifully again.

Many thanks to all the dev team.
