08/12/2018 — Happy Permutation Day!

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

In addition to being a Permutation Day, today’s date can also be read as a palindromic number, since 81218 reads the same forwards and backwards.

Celebrate Permutation Day by mixing things up! Try doing things in a different order today. Just remember, for some operations, order definitely matters.
