The last link I gave for my QPR calendar was a bit wonky.
If you want to subscribe to the calendar with iCal, choose “Subscribe…” from the “Calendar” menu and enter the following URL:
Don’t just follow this link in your browser. Doing that would download the calendar events and import them into your iCal calendar. That’s not as good as subscribing, as you won’t automatically receive any updates.
You can also view it on the web here.
