I use Thunderbird out of principle, and Google Calendar, as I haven't found anything equivalent to achieve shared calendars with other other users. Therefore I have to sync both tools ... in both directions.

... and this add-on helps me achieving exactly this since many years. It provides great benefits to me. Thanks for this add-on!
