The 2014 World Cup in Brazil is from June 12th - July 13th with the group stages (most US games) from June 13th-26th.
Join the facebook events:
1. USA vs. GHANA: Tuesday June 17th 8am (7pm June 16th in Brazil)
2. USA vs. PORTUGAL: Monday June 23rd 7am (6pm June 22nd in Brazil)
3. USA vs. GERMANY: Friday June 27th 2am (1pm June 26th in Brazil)
The two daylight savings time changes in opposite directions make it a little tricky to predict the times, but I think I've more or less got it.
We'll get together to watch whichever US game is on a Saturday/Sunday at 11am: June 14/15, 21/22.
