My grandmother has a pair of calendar cubes; each cube has six digits on it, one on each face.
Every morning, she re-arranges them to show the day of the month as a two-digit number (01 to 31).

Even though some numbers appear on both cubes, you can easily tell them apart because one cube is ivory and the other is brown.
I noticed that it was possible to use the ivory cube in the tens place and the brown cube in the ones place for SEVEN days in a row (within one month)!
Can you figure out what digits are on each cube?



Answer

The ivory cube has 012345; the brown cube has 012678.
The 6 on the brown cube is also a 9, just turn it upside-down!

There are two times each month where it is possible to keep the ivory cube in the tens place for seven days in a row:
06 07 08 09 10 11 12 and 16 17 18 19 20 21 22.
