Calendaring Extensions to WebDAV, or CalDAV, is an Internet standard allowing a client to access scheduling information on a remote server. It extends WebDAV (HTTP-based protocol for data manipulation) specification and uses iCalendar format for the data. The protocol is defined by RFC 4791. It allows multiple client access to the same information thus allowing cooperative planning and information sharing. Many server and client applications support the protocol.


  1. The University of Wisconsin's WiscCal service, launched in 2012, sets the gold standard for CalDAV-based calendar management. UW's Division of Information Technology (DoIT) group seems to have got all the details right, including extensive and user-friendly documentation. UW doesn't disclose the type of CalDAV server upon which it built WiscCal, but I guess it's Oracle Beehive.
  2. UB CSE is giving CalDAV-based calendar management a try. We implemented it with the free FreeBSD port of the DAViCal server.


This page shows events in iCalendar format:

UB Career Services maintains a list of events in XML format. We wrote a script to reformat them in iCalendar format for import into our community's CalDAV and Google calendars.
