The Darwin Calendar Server is a standards-compliant server that allows multiple users to collaboratively share calendaring information. It provides a shared location on the network to store schedules, and allows users to manage and send invitations. It was publicly released during Apple's Worldwide Developers Conference on August 7, 2006. The version shipped with Mac OS X Server v10.5 is called iCal Server.
The server, named "caldavd", is a daemon background service. It has been ported to non-Apple computer platforms. It is currently possible to install it on FreeBSD and several flavours of Linux. The server is written in the Python programming language, and uses extended file attributes and the Twisted framework.
The Source Code Management project for Darwin Calendar Server is located at Mac OS Forge.
