The Sunbird Project is a redesign of the Mozilla Calendar component. Our goal is to produce a cross platform standalone calendar application based on Mozilla's XUL user interface language. At the moment the "Sunbird" name is a project name. It is not official and may change in the future.
Our intended user is someone who uses Mozilla Firefox (or another browser) as his browser, Mozilla Thunderbird (or another mail client) as his mail client and wants a calendar application based on Mozilla.
Please note that Sunbird is still an experimental technology preview and these builds contain bugs and are a little bit rough around the edges.
