Why Do Clocks Move Counter-Clockwise?

The Lefty Clock

Imagine you are looking at a shadow on the ground. As the sun moves from left to right in the sky, the shadow rotates to the left. This is called counter-clockwise! But wait, clocks go the other way.

Why Did They Change?

Long ago, people used sundials. The North Sundial had shadows that moved like the hands of a clock today. It went from top to right, then bottom, then left. People thought this was the natural way for time to pass.

A Happy Accident

When makers built mechanical clocks in Europe, they copied the sundial. They did not know if it was right or wrong; they just copied what they saw. Even though the sun actually moves across the sky differently depending on where you stand, we stuck with the sundial pattern. Now, almost everyone agrees that time flows clockwise without even thinking about it!
