Darwin Calendar Server

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 send each other and manage invitations.

In order to provide interoperability with multiple calendaring clients, the server implements the ​CalDAV protocol, which is an extension of ​WebDAV, which is in turn an extension of ​HTTP.

NOTICE

This server is getting a fair bit of traffic right now due to the ​WWDC announcements and associated spread of interest. We're certainly excited about the interest, but please keep in mind that this site may be slow and/or unresponsive for a few days or so while traffic normalizes and we get the configuration smoothed out a bit. We've disabled the source broswer in Trac for the time being, since that seems to be having some troubles. Stay tuned.
