Default Birthday Primes

Were you born on a Prime day of the year? or in a Prime year?

This is a multivote.

No need to post your actual digits.

And so is my parking tag at work (1213) and my 9-digit work phone yeah, right!.

Neither YYYYMMDD nor DDMMYYYY are prime for me.

Hey, it's only the year for me too, and I'm not that old.

Everything about mine is divisible by 4! So, not a prime person, but no woe either.

No primes. If I'm in the same age range as Batalov guesses for cheesehead, that leaves 11,711 possibilities (or 12,189 depending on how you count) for me.

Of course I may be outside the range...

Just 273 possibilities for you in that range.
