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.

Today is also a single-transposition day, since the each string can be formed by simply transposing the 0 and the 2 in the other string.

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