Prime dates
==================================
1999-11-19, Magnus Bodin <magnus@bodin.org>

The "prime date" 1999-11-19 has all prime numbers in it. In that respect that 
both 1999, 11, and 19 is a prime number. The next time THAT will happen is 
2003-02-02. (On each prime year, there is actually 82 prime dates.)

Then, if you write the date as one single number, then it is a lot of them. 
This is just a few examples: (where it is primes in at least 2 of the columns)
