Calendar Posting Glich

For some reason the calendar will not allow me to post a game date of July 4.  Other days work OK but not July 4.  I looked and there are other games on July 4 but for some reason I can not get it to register for my game.

What is happening when you try to change the date?

Nothing.  When I select the date then it jumps to the time.  When I select that it jumps back to the game screen but nothing has changed.  Just tried it again and this time it went to the minutes page after the hours being set which it was not doing before.  I selected that and was able to reset the game to the July 4 date.  Not sure what was causing the problem but it seems to be working correctly now.  Thanks for the response.
