Sundials are used to tell time by utilizing the position of the sun's shadow cast by a gnomon (a vertical stick or triangular blade) on a marked surface. As the sun moves across the sky, the shadow indicates the hours of the day based on the angle of sunlight. They also provide insights into the Earth's rotation and the passage of time in a natural and historical context. Additionally, sundials can serve as decorative garden features while connecting us to ancient timekeeping methods.
