- ★WHAT DOES A SUNDIAL COMPASS DO:The protractor is used to set the sundial to the correct latitude angle, while the compass is used to find true north based on the area's magnetic north declination. Once your sundial compass has been leveled, set to the correct latitude, and to true north, a shadow will be is cast onto the sundial's face by the gnome.
- ★HOW DO SUNDIAL WORKS: When the earth rotates about its axis, the sun appears to “move” across the sky, causing objects to cast shadows. A sundial contains a gnomon, or a thin rod, that casts a shadow onto a platform etched with different times.
- ★WHAT IS A SUNDIAL USED FOR: A sundial is a clock that uses the position of the Sun to indicate the time. Typically a rod casts a shadow upon a plane or surface. On this surface are found markings that indicate the time by the position of the shadow.

◆Ares India 3" brass sundial compass with box◆CAN YOU USE A SUNDIAL COMPASS AT NIGHTA sundial is designed to read time by the sun. This places a broad limit of two minutes on accurate time because the shadow of the gnomon cast by the sun is not sharp. Looking from earth the sun is ½° across making shadows fuzzy at the edge. The actual construction of a sundial can be very accurate.◆HOW CAN SHADOWS BE USED TO TELL TIMEStand outside in a clear spot so your shadow projects on the ground rather than a wall. Have a helper measure the length of your shadow. Your shadow will be longer in the beginning and end of the day, and shorter toward the middle. Look up your shadow's length on the Personal Sundial chart to determine the time.
