Happy Prime Date --- sorry for being so late

petrw1 · 2011-05-24, 04:20

These dates are about as rare as Mersenne Primes.

Today: 20110523 is one of those rare days where all the following are prime:

Year: 2011
Month: 5
Day: 23
Month-Day: 523
Entire date: 20110523

P.S. My age at this time is also a prime number.
