Lightning is an add-on extending Thunderbird or Seamonkey to integrate standards-based calendaring. Lightning provides for managing calendar data, subscribing to iCalendar feeds (RFC5545), interacting with calendaring services, chiefly CalDAV (RFC4791), and receiving and sending iTIP/iMIP email invitations (RFC5546/RFC2447).

Sunbird was a standalone, standards-based calendaring application for managing calendar data, subscribing to iCalendar feeds (RFC5545), and interacting with calendaring services, chiefly CalDAV, built with many of the same components as Lightning (and without email integration). It is no longer supported or developed - The Calendar Project has stopped Sunbird development to focus on Lightning, so Lightning is currently a safer choice for new users. And time zone information is no longer updated.

Stable releases of Lightning can be downloaded from the project's web site. See download sites. If you experience slowness or instability you should file a bug report.

  • Make backups periodically: crashes may corrupt calendar data. Local calendar data is located in the user Profile folder (Thunderbird, SeaMonkey, Sunbird):
    • in the preferences file (profileDir/prefs.js) and
    • in the local-calendar database (profileDir/calendar-data/local.sqlite).

Lightning and Sunbird are based on a rewrite of Calendar Extension, which is no longer in active development. Development was originally started at OEOne corporation (Canada, now named Axentra), and later for periods a few developers were supported by Oracle (US), Sun Microsystems (Germany, later aquired by Oracle), and by Mozilla Messaging, as well as by volunteers and donations from around the world.
