Question 1) Make a day-of-the-month calendar made of wooden blocks. There are two six sided wooden cubes, and by choosing which face is displayed for the two of these, all possible monthly dates (from 01, 02, …, to 29, 30, 31) can be displayed; note the single digit dates must start with a 0. Your job is to write one digit (from 0, 1, 2, …, 8, 9) on each face of the two cubes so that this can be done. Good luck! Bonus question: how many distinct solutions are there?
