The Fascinating Puzzle of Calendar Dice: Displaying Dates
Written on
Chapter 1: Understanding Calendar Dice
Calendar dice, a charming accessory found on many German office desks, allow users to showcase the current day of the month. These two dice, housed within a small box, are both decorative and puzzling, as it may not be immediately clear how to represent every date from 01 to 31 using just two dice.
To solve this intriguing puzzle, we must determine which numbers should be placed on the dice to cover all possible dates within a month. Given that we have ten digits (0-9) but only six faces on each die, we cannot display all ten numbers on each die. Thus, we need to make careful choices. What is the optimal selection to ensure all days can be shown?
Before proceeding to the solution, take a moment to think about it yourself.
Each die can display six different numbers. To represent the 11th and 22nd of the month, both dice must include the numbers 1 and 2. Furthermore, to accurately depict the days from 1 to 9, each die must also feature the number 0.
Die A: 0, 1, 2
Die B: 0, 1, 2
Next, we need to allocate the remaining numbers—3, 4, 5, 6, 7, 8, and 9—across the two dice. However, this leads us to a dilemma:
Die A: 0, 1, 2, 3, 4, 5
Die B: 0, 1, 2, 6, 7, 8, 9
Here, Die B ends up with seven numbers, exceeding the limit of six. How can we resolve this?
After some thought, the solution becomes clear: instead of a 9, we can use a 6 turned upside down, which serves as a 9. Thus, we finalize the configuration as follows:
Die A: 0, 1, 2, 3, 4, 5
Die B: 0, 1, 2, 6, 7, 8
Of course, the arrangement of the numbers 3, 4, 5, 6, 7, and 8 can be done in various combinations, resulting in numerous potential configurations for the dice.
