Mozilla Sunbird is a free and open source, cross-platform calendar application that was developed by the Mozilla Foundation, Sun Microsystems and many volunteers. Mozilla Sunbird was described as "... a cross platform standalone calendar application based on Mozilla's XUL user interface language." Announced in July 2003, Sunbird is a standalone version of the Mozilla Calendar Project.
It was developed as a standalone version of the Lightning calendar and scheduling extension for Mozilla Thunderbird. Development of Sunbird was ended with release 1.0 beta 1 to focus on development of Mozilla Lightning.
Sun contributions 
Sun Microsystems contributed 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 were 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.
Trademark issues and Iceowl 
Although released under a MPL, MPL/GPL/LGPL tri-license, Mozilla Sunbird suffers from trademark restrictions that prevent the distribution of modified versions with the Mozilla branding.
As a result the Debian project created Iceowl, a virtually identical version without the branding restrictions.
