2025 Dodecahedral Calendar (DIY)

As one of the five Platonic solids, the dodecahedron is a three-dimensional shape that has 12 faces, making it the perfect shape to represent the months of the year. In mathematics, the dodecahedron is more than just a shape — it's a key object for understanding symmetry, geometry, and group theory.

Its unique properties continue to inspire mathematicians and serve as an important tool for exploring the relationships between shapes in higher dimensions.
