You "moved" a rather similar line:
372      -            var bDay = new Date(1975, 5,4);
to:
  381    +            var bDay = new Date(1976, 6,4);

I assumed it was a straightforward move (I was too lazy to verify that it wasn't a straightforward move).
I wanted to acknowledge that I was aware that your source didn't have good style -- i.e. it wasn't precisely your fault that there was a space missing.
