February 2018 Brain Puzzler Solution

Q: For a calendar, with two six sided dice make all possible monthly dates using two digits  (from 01 to 31) by writing one digit (from 0, 1, 2, …, 8, 9) on each face of the two dice.
A: It does not seem like it can be done — but…the Eureka part of the answer is:
the 9 is the 6 upside and vice versa!
Dice 1: 0 1 2 4 5 7 and  Dice 2: 0 1 2 3 8 9 (9 is also 6)
or
Dice 1 : 0 1 2 3 4 5 and Dice 2 : 0 1 2 6 7 8 (6 is also 9)
