=== Overview ===

Debian is using the [[http://en.wikipedia.org/wiki/ICalendar|iCalendar]] format in various ways.

 * Who
  * Some of the iCalendar data is for the whole Debian community, such as data about major events.
  * Other data sources (such as tasks for outstanding RC bugs) are mainly useful for developers and package maintainers.
 * What
  * iCalendar is a generic format for representing events and tasks.  It is defined in [[http://tools.ietf.org/html/rfc5545|RFC 5545]].
  * There was a Mac OS application called iCal, but the iCalendar standard is not an Apple proprietary standard and it is widely supported.
  * See the list of data sources below for some iCalendar data
 * How
  * iCalendar is a data format
  * iCalendar data can be distributed in various ways, e.g. by file, email attachment, served over HTTP (usually read-only) or two-way synchronization using CalDAV over HTTP
  * See the list of packages below to get started
