Summary

An equatorial sundial is a type of solar clock where the dial plate is tilted parallel to the Earth’s equator. At its center, a gnomon (a rod or stick) points toward the Earth's rotational axis—aiming at the North Star in the Northern Hemisphere. As the Sun moves across the sky, the shadow of the gnomon sweeps across the marked dial, showing the solar time. For accurate readings, the sundial must be aligned to true north and tilted to match the latitude of its location. This type of sundial tells true solar time.

This equatorial sundial was designed in a flat-pack format: all parts are cut flat and easily assembled without glue or screws.
