It’s among six WHATS this century?

A perfectly odd WHAT?
Why isn’t 5/7/11 perfectly odd? or 5/7/13? Or 5/9/13? or 5/11/13?
I think they have to be in sequential order, i.e., 1/3/05, 3/5/07/, 5/7/09,...11/13/15. Sadly, when written out without the slashes, none of these are prime. Now that would have been something to celebrate!
