It's strange, but I couldn't find any shared calendars for DrupalCon. So I figured that could be changed. (There is an iPhone app available, though!)
Below are links for a Google Calendar with titles, rooms and links to all DrupalCon sessions. I might be adding more stuff later on – like BoFs and party stuff.
I hope it may be of use to someone (apart from me)!

The ID for the calendar is cctgn5hcblfnsp5mpeu06a6jc0@group.calendar.google.com, in case you want to add it manually to a Google Calendar of yours.
(Please leave a comment if you find something weird in the schedule.)
