Thousands of Shared iCal Calendars

I made a post yesterday about how you can use iCal to subscribe to new movie releases. Sean Corfield mentioned that he is subscribed to US and Indian holiday calendars, which got me wondering what other calendars were available out there. Apparently there are thousands. It looks like the two big repositories are the Apple iCal Library, and iCalShare. Very cool stuff. I’m now subscribed to US holidays (I never know when it’s a holiday, and I sometimes go to work when Macromedia is closed), and a video game related calendar.

Is there something similar out there for Outlook users? Yesterday, Dan mentioned WinDates which looks like a good solution, although personally, I would recommend just switching to a Mac. 🙂
