Why Clocks Go Right

Long ago, people had no clocks. They used the sun. They built sundials. A sundial has a flat plate. It has a stick in the middle. The stick makes a shadow.

The sun moves across the sky. It rises in the East. It sets in the West. In the Northern Hemisphere, the shadow moves in a special way. The shadow moves from left to right. We call this "clockwise."

People liked the sundial. It helped them know the time. Later, people made mechanical clocks. They wanted these clocks to show time like the sundial. So, they made the hands move the same way as the shadow.

If the first clocks came from the Southern Hemisphere, they might move differently. In the South, shadows move the other way. But the first clocks were made in the North. That is why your wall clock moves to the right today.

Clocks follow the sun. The sun moves in a circle. The shadow follows the sun. We follow the shadow. This is why time goes "clockwise." It is a memory of the sun and the old sundial.

Do you have a clock in your room?
