A solar dial, also known as a sundial, is a timekeeping device that uses the position of the sun's shadow to indicate the time of day. It typically consists of a flat plate or surface marked with hour lines and a gnomon, which is a stick or triangular blade that casts the shadow. As the sun moves across the sky, the gnomon casts a shadow that falls on the hour lines, allowing users to read the time based on where the shadow points.
