It is Google Calendar.
I was lucky to spot Interesting Google Calendars and found out that this helps add the 'FIFA World Cup 2006' and 'iWorldEvents Calendar' to the Google Calendar.
I was searching Google for "Fifa world cup charts and schedule excel" when I spotted "World Cup Games on your Calendar and Predictor Charts-FIFA World...", on top of my my Excel 2006 FIFA World Cup Germany Timeline....
Google Calendar, of course, in itself will be a nice, useful planner to help me work out and organize my schedule. And how will it be turning out to be different from my Excel calendars.
