Sunbird and Lightning Calendars

A powerful, standalone, standards-based calendar

Sunbird is still in the early stages of development. Although it is already quite stable, it is recommended for testing purposes only.

Alpha test builds for public testing are made available from time to time. They can be downloaded from the project's web site:

Sunbird - Download

If you prefer a calendar that is integrated with your e-mail, then you can install the Lightning extension in Thunderbird.

Sunbird and Lightning are based on a rewrite of Calendar Extension, which is no longer in active development.

To follow the progress of Sunbird and Lightning, see the Calendar Weblog.

You can discuss Sunbird and Lightning in mozillaZine's Calendar forum.
