Have you allowed for time differences? USA 94 if they played late on the 13th would mean it was already the 14th here. Would an early kick off on the 15th do it for the Japan and South Korea world cup as well, or is the time difference too small?
In 1994 they didn't play their opener against Ireland until the 18th, and in 2002 they played a late kickoff on the 13th which means it would have been one of the many morning games we had here.
