The surprising reason behind the direction every clock on Earth follows
Location: Rishon LeZion
Ever stopped to wonder why clocks go THIS way and not the other? It turns out it's not random at all, and the answer goes back thousands of years to sundials in the northern hemisphere. This is Part 3 of Wait, What?!, the series that takes the things you never thought to question and actually answers them. 🕐
This short educational video, part of the Wait, What?! series (Part 3), explores the surprisingly deep history behind why clocks rotate in the direction they do. The animated explainer presents a clock face against a dark starry background and poses the question: why do clocks go this way? The answer traces back to ancient sundials used in the northern hemisphere, where the shadow cast by the gnomon moves from left to right as the sun travels across the sky. Early clockmakers replicated that familiar shadow motion when designing mechanical timepieces, cementing what we now call clockwise as the universal standard. The video uses clean motion graphics and bold typography to make the concept immediately engaging and accessible for all ages. It is part of an ongoing curiosity-driven series that unpacks everyday phenomena most people never think to question.
Because early mechanical clocks were designed to mimic the movement of shadows on sundials in the northern hemisphere, which sweep from left to right.
Almost certainly yes, sundial shadows in the southern hemisphere move right to left, so clockwise would likely be the opposite direction.
