Day Cubes

We made it through another week! Here's a fun problem to start off your weekend.

You have two cubes on your desk. Every day you have to arrange both cubes so that the front faces show the current day of the month (01-31).

What numbers are on the faces of the cubes to allow this?

Note: You can't represent the day "7" with a single cube with a side that says 7 on it. You have to use both cubes all the time. So the 7th day would be "07".

    Cube 1: 0 1 2 3 4 5

    Cube 2: 0 1 2 6 7 8

    And 6 doubles as a 9 of course

    • Mark one cube Monday-Saturday
    • Mark the other 1-4
    • signify day at the Xth day (ie. the 2nd tuesday)
    • the numbered cube contains a sunday, which is used in conjunction with the day'd cube (interpreted as numbers)
    • it's all about the interpretation
    • (I realize I might have broke the "numbers only" rule)

    0-1-2-3-4-5 1-2-6-7-8-9

    Rules said from 01-31 so having both cubes with 0 didn't make sense.

    You can't represent the 3rd, 4th or 5th day of the month with that set. The 2nd 0 is a necessity.
