What Is an Hour?
An hour is a unit of time equal to 60 minutes or 1/24th of a day. It’s how we plan our lives, measure routines, and track our time on Earth.
Think of it as your life’s currency. Now you can see how much you’ve spent!
A Brief History of the Hour
The hour has ancient roots. From Egyptian sundials to Babylonian timekeeping, humanity divided days into 24 parts.
Fun fact: The number 60 (minutes/hour) comes from the sexagesimal system, used over 4,000 years ago!

Why Are There 24 Hours in a Day?
The 24-hour day came from Egypt, where sundials split daytime into 12 parts. Night was divided into 12 “watches.”
Together, they form the 24-hour day we use today.
