On the faces of the first dice, you can write 0, 1, 2, 3, 5 and 7
On the faces of the second dice, you can write 0, 1, 2, 4, 6 and 8.

It is simple to crack. Basically, we need 1 and 2 on both the dices to display 11 and 22. Also, we need 0 on both the dices to display dates from 01 to 09.

Now we have taken every number on either dice except. This is the tricky part. Whenever you want to use a 9, you can simply rotate the face with 6 180 degrees.
