Calendar Cubes (Posted on 2002-09-09) Difficulty: 3 of 5
A businessman has two cubes on his desk. Each cube has a number on each of its sides. Every day, the businessman arranges the cubes in such a way that the upward facing numbers display the day's date. (Note that both cubes are always used for this, so on the 7th of the month, the cubes' surfaces display "07".)

How are these cubes numbered? (I.E. What numbers are on which cube? - call them C1 and C2.)

Heh. This is an odd question - my nan actually had a calendar thing sat on her TV that was constructed in this way - two cubes for the day number and one cube for the month (with the container constructed so you could only see half of the month block's face, so you could get away with two months per face) - I loved it when I was a kid...
