Caesar’s Calendar Puzzle

A reusable date puzzle with ten movable pieces. Rearrange them to leave the chosen date visible, making a daily calendar change into a fresh spatial problem.

The board uses ten movable pieces to reveal a chosen date through their arrangement. The maker specifies ages 14+; it is a reusable puzzle, not an automatic calendar.

Why we’d gift it

For someone who likes giving the desk a daily hands-on challenge.
