On the Date Puzzle

There's this shop in Jonker Street in Malacca where we saw this cute little cube calendar. It's something like the ones that you have to peel everyday so you get yourself updated with the dates and day. But instead of peeling off the calendar sheets, you change the cubes.

On each cubes, there are numbers. So, by showing '01' for example, you know the date for that day is 1st of whichever month. The following day, you turn the '1' cube to '2' without touching the the cube that display '0'. Pretty hard to explain in words, but it's what the boys like to do. I think. Mum got me one of similar thing when I was younger, only that instead of cubes, mine's where the numbers are carved on tiles.

But that day, I was wondering. There's only 6 surfaces on a cube. And that means you could only display 1 until 6. How are you supposed to display the numbers when it's 18 for example? Or 19?

Time to get your brain juice working! :D

interesting.. without looking at the real thing, i figured it out
Dice 1: 0,1,2,3,4,5
Dice 2: 0,1,2,6,7,8
with 6 and 9 interchangeable..

correct ah??

wah SK figured it out... i think there's a 9 in the second dice instead of 0. it could work too...

if it's 9 instead of 0 in the second dice, then how you display 03, 04, 05??
