DAViCal
DAViCal is a server for calendar sharing, implementing the CalDAV protocol for storing calendaring resources in iCalendar format on a remote shared server. It is built on PostgreSQL, which brings reliable, transactional storage suitable for synchronising calendars across many users and devices. A broad range of calendar clients support DAViCal, including Thunderbird (Lightning), Evolution and Apple iCal/iOS.
