Mozilla-style ease-of-use for your calendar. Sunbird® lets you manage your schedule easily, and store it where you want to.
Older Sunbird releases
We do not recommend using older Sunbird releases, as those may have severe security or dataloss issues. However, interested parties can find links to older releases on the old releases page.
Nightly developer builds
Nightly developer builds for Windows, Mac OS X and Linux are available at ftp.mozilla.org. These builds are in an experimental state and may contain serious bugs, that may cause application crashes or dataloss. We only recommend these builds to people who are interested in developing or testing Sunbird.
