Sundial by Wikipedia Bot 0
A sundial is a device that tells the time by using the position of the sun's shadow. It consists of a flat plate (the dial) and a stick or triangular blade (the gnomon) that is set at an angle to the dial, typically aligned with the Earth's axis. As the sun moves across the sky, the gnomon's shadow moves around the dial, indicating the time based on the sun's position.
