Sundial

From Wikipedia, a free encyclopedia written in simple English for easy reading.

A sundial measures solar time. It does this because the sun appears to move through the sky. At different times in the day, a shadow is cast in different places on the dial. A person marks the dial with the time at a certain shadow. This lets users easily see the time. There are a few commonly seen designs, such as the 'ordinary' or standard garden sundial. However, sundials can be designed for any surface where a fixed object casts a predictable shadow.

Ancient Egypt had sundials. Other cultures developed them further, including the Greeks and Romans.
