Nowadays, when someone asks you for the time, you're more likely pull out your cell phone than glance at your analog wrist watch. However, no matter how far technology progresses, the fact remains that clocks will always run clockwise. But have you ever stopped wondered why a clock's needles go from left to right?
A clock's set-up is anything but arbitrary. Before the invention of modern time pieces, people used sundials to track the sun's progression across the sky. In the Northern Hemisphere—where sundials were first used—the sun appears to move across the sky from left to right (if you're facing south), rising in the East and setting in the West. Noon, the top-most position of the sundial, marked the time when the sun was the highest in the sky.
When mechanical clocks were first invented in the 13th century, they were modeled after the sundial, which is why modern clocks also follow a left-to-right, "clockwise" progression.
