Calendar Cube 3×3 is a functional calendar built around a 3×3 cube mechanism. Instead of a normal color scheme, the markings are arranged so that the puzzle can display every date of the year when solved into the correct configuration.

The idea is to keep it on a desk and set today’s date each morning — a short daily brain exercise that also works as decoration.

Who it’s for

• 3×3 fans who want a practical variation on familiar mechanics.
• Office, desk or gift use.
• Anyone who enjoys small daily logic challenges.

How to use it

• Arrange the required markings on the visible faces to display the chosen date.
• Unlike a normal 3×3, the goal is not simply to restore colors but to build the correct calendar combination.

Size and mechanism

• Dimensions: 56 × 56 × 56 mm.
• Weight without packaging: about 70 g.
• Non-magnetic.
