Wow that's early. Why couldn't World Cup schedule it at a better time like they did on last Saturday?
They could schedule it later by a couple of hours, but the second set of matches occurs at 12:00 Pacific, 15:00 Eastern. Of course Germany is UTC+2 (I believe), so the times of these matches are in the afternoon and evening (and spread apart enough so that people can get drunk between matches--like they should!).
There are games every day; not all games can be scheduled on the weekend. Also, the games are in Germany, so the first two games kickoff at 4pm Germany time and then the last two at 9pm Germany Time.
I don't think FIFA is going to schedule games based on what's convenient for the United States. FIFA is not an India-based call center.
