01/22/2012 — Happy Permutation Day!

Published by patrick honner on

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

We enjoyed several Permutation Days in 2011.  In addition to predicting future dates, an interesting question would be “Which year has the most Permutation Days?”

In honor of today, I recommend changing the order in which you do things!
