Play Date Calendar

Give your desk a fun and functional little upgrade with the Play Date Calendar Cube. Inspired by one-a-day digital word games, this analog puzzle combines that daily problem-solving ritual with a dexterity challenge that engages both your hands and mind. With its clever design, solving each of the 365 days of this perpetual calendar takes just a handful of twists. The cube itself is exponentially easier to solve than a traditional Rubik's Cube: only one face needs to be solved, and the date is assembled by twisting the faces in an intuitive way - no complicated algorithms required. Interactive, satisfying to use, and always ready to spark a conversation wherever it sits, it is the thoughtful details that make it a joy to use every day. The ashwood display case holds the cube at an ideal 15° viewing angle, while just one finger tips it forward on its rubber feet, sliding the cube right into the same hand. After the solve, the satisfying air-cushion damping eases it back into the case. Designed by Sean Dempsey of Charlie Ray Design, Play Date is a clever take on the perpetual calendar, blending modern style with everyday function.
