The hidden logic behind why our clocks stop at twelve
In short: We check our watches dozens of times a day, but rarely consider why the face ends at 12 instead of 24. This video explores the ancient history and mathematical convenience that shaped how we measure time.
The transition from celestial observation to mechanical measurement is rooted in how ancient Egyptians divided their days and nights. The number 12 emerged as a primary unit for measuring time due to its high utility in early systems of calculation.
While the 24-hour day eventually became the standard, mechanical clocks adopted the 12-number face we recognize today. This evolution reflects a long history moving from tracking the sun and stars to the standardized gears of modern watches.
