Why Do Clockwise and Counterclockwise Exist?

Imagine the sun is a big yellow ball rolling across the sky. In places where we learned to tell time (like in Europe), the sun starts on your right and moves to your left. This path looks like it is going right around a circle.

The Big Clock

When people built the first mechanical clocks, they copied this movement so it would make sense. If you stand facing south, the sun rises on your left (East) and sets on your right (West). It moves across the sky in an arc that goes from top-left to top-right.

So, when we draw a clock, we start at twelve and move toward one o'clock. This direction is called clockwise. If you go the other way, it is like going against the sun's path.

Examples

  1. The shadow on a garden sundial moves right around like a clock hand.
  2. If you drive in circles to the right, you are going clockwise.
  3. A spiral staircase going up to the right follows the sun's path.
