A pyramid is a polyhedron with a polygon as a base where each vertex connects to another point on a different plane as the base. Many of the pyramids built by people use a square base, and thus are not tetrahedrons. Every tetrahedron is a pyramid, but not every pyramid is a tetrahedron. We celebrate tetrahedrons on March (3rd month) 4 because it's composed of triangles (3-sided polygons), and 4 of them.
