Today could also have been a "perfect prime day" if MM, DD, YY and YYYY had been prime (in addition to the above). But it's not the case...
11 -> is prime
29 -> is prime
13 -> is prime
2013 -> not prime (3 x 11 x 61)
Too bad! We will have to wait another 16 years before we have a perfect prime day...
