A sundial is a perfect example of using a shadow to tell the time during the day. As the Sun moves across the sky, the shadow cast by the sundial moves round in a circle, and the circle is marked in hours and minutes.
A sundial is an outdoor device that shows the time by casting a shadow onto a dial marked with lines indicating the hours of the day. The position of the shadow changes as the sun moves across the sky, allowing people to tell time based on the angle of the shadow.

If you place yourself on the equator at a the time of an equinox, then at mid day your shadow falls directly under your feet because the Sun is directly above you. As the Sun rises to this position and set form it, you shadow will fall to one side of you and the length of this shadow will depend on the height of the Sun in the sky, the shorter it is the higher the sun will be. Thus from the length and position of your shadow you can tell what time it is. Long shadows happen in the morning or evening and short shadows happen towards mid day.
Sundials tell the time by the shadows cast by the sun onto a circular calibrated surface, much like a clock but without mechanism or chips.

You can use a sundial, which is a device that uses the position of the sun's shadow to tell time. By placing a stick or pointer on the sundial, the shadow it casts can indicate the time based on markings on the sundial's face.
