12/03/2013 — Happy Permutation Day!

Published by MrHonner on

Today we celebrate a Permutation Day!  I call days like today permutation days because the digits of the day and month can be rearranged to form the year.

12032013Not only is today a permutation day, but it is also a double-transposition day!  We can turn the month and day into the year by first transposing the ‘1’ and the ‘2’, and then transposing the ‘1’ and the ‘0’.  Permutation days are also nice because, unlike Palindrome days, they can celebrated on both sides of the Atlantic without heated disagreement.

As usual on Permutation Days, I suggest celebrating by mixing things up!
