12/20/2012 — Another Permutation Day!
Today we celebrate our final Permutation Day of the year! I call days like today permutation days because the digits of the day and month can be rearranged to form the year.
Not only is today a permutation day, but it is also a transposition day! A transposition is a rearrangement that simply swaps too things, like ’12’ and ’20’.
Celebrate Permutation Day by mixing things up! Try doing things in a different order today, or maybe try swapping two things in your schedule to honor today’s transposition!
