Calendar

The Mozilla Calendar Project is a community driven project based on the Mozilla application architecture. The Project's heart is a calendaring backend based on libical. The Lightning extension is built on top of this platform and provides integrated calendaring capabilities for Mozilla Messaging's Email client Thunderbird.

Mozilla Calendar emphasizes free and open source technology and supports standardized technology like the ical/ics (rfc2445) format and the CalDAV (rfc4791) protocol, which is implemented by many freely available servers and also some commercial providers.
