Noírín has put up a calendar for ApacheCon EU 2006 to which you can subscribe from iCal (if you’re on a Mac). I have set mine to update once an hour in case the schedule changes.
On a slightly related note, Apache legends Rich Bowen and David Reid have started Feathercast, a series of Podcasts on Apache related topics. You can subscribe to it in iTunes by choosing Subscribe to Podcast… from the Advanced menu, and typing http://feathercast.org/?feed=rss2 in the URL box. iTunes will then automatically download new episodes as they appear.
