A sundial is an ancient timekeeping device that uses the position of the sun to indicate the time of day. It consists of a flat plate or dial with a pointer or gnomon that casts a shadow. As the sun moves across the sky, the shadow moves around the dial, indicating the hour.
Sundials have been used for centuries to tell time, and they are still popular today as decorative objects or as a way to learn about the movement of the sun. They are relatively easy to use, but there are a few things you need to know to read a sundial accurately.
