March 30 is 7 TeV day.
It seems a very complex process getting LHC set up just right, so I wouldn't be surprised if there are some delays, but it should be damn exciting for those involved. Of course, the LHC is rated up to 14 TeV collisions, but they are restricting themselves to half for this year to make sure they get some results without things going boom again.
