Mozilla Sunbird

Version: 0.9 Mozilla Sunbird is a cross-platform calendar application, built upon Mozilla Toolkit.

Announced in July 2003, Sunbird is a standalone version of the now discontinued Mozilla Calendar Extension. It is currently developed as a standalone version of the Lightning extension for Mozilla Thunderbird that provides a calendar to the mail management application.

Sun Microsystems has been contributing significantly to the Lightning extension project to provide users with an alternative free and open source choice to Microsoft Office by combining OpenOffice.org and Thunderbird/Lightning. Sun's key focus areas in addition to general bug fixing are calendar views, team/collaboration features and support for the Sun Java System Calendar Server. Since both projects share the same code base, any contribution to one of them is a direct contribution to the other.
