A sundial is a device that tells time based on the sun's relative position. It has a triangular part that stands up from the dial, casting a shadow that points to different parts of the dial through the day. It needs to be set up for where it will be used, and daily equation of time offsets need to be manually compensated for.
Sundials are timekeeping devices that use the position of the sun to indicate the time of day. They consist of a flat plate, called the dial, with a raised pointer, called the gnomon. As the sun moves across the sky, the shadow cast by the gnomon moves across the dial, indicating the time. Sundials work by aligning the gnomon with the sun's position to accurately track the time throughout the day.

Why does the portable sundial need a compass?
The compass on a portable sundial helps the user align the sundial accurately north-south, which is crucial for it to give accurate time readings based on the sun's position. By pointing the sundial's gnomon (the part that casts a shadow) towards true north using the compass, the sundial can accurately indicate the time.
