"For 2012 they fall on May 29th, and July 12th" and "These two days happen to correspond with Memorial Day and Baseball's All Star break".

More mystic crap. Memorial Day in 2012 is May 28, not May 29 and the MLB All Star Break beings July 9. Neil deGrasse Tyson shouldn't even write like this, getting drawn into mystical interpretations, even in jest, just reinforces the idea that it's worth thinking about crap like that.
