If anyone is interested in an English-only but localized World Cup 2010 Google Calendar, I found one. You can also download in XML, iCal or HTML. Just make sure that the calendar is properly adjusted for your timezone. Right now, it’s set in America/Toronto (for me) but your’s could be anything from this list.
For example, the URL ends with America/Toronto but if you’re in Singapore, you might want to use Asia/Singapore. So change the end of the URL from America/Toronto to Asia/Singapore and hit enter. Now you can export the calendar into your timezone.
Good luck and enjoy World Cup 2010!
