What Is an Hour, Really?
An hour is a unit of time equal to 60 minutes or 1/24th of a day. But it’s more than that—it’s how we plan our lives, measure our routines, and understand our time on Earth.
Think of it as your life’s currency. And now, you can see exactly how much of it you’ve already spent.
A Brief History of the Hour
The hour has ancient roots. From Egyptian sundials to Babylonian timekeeping, humanity has long divided days into 24 parts.
Fun fact: The number 60 (as in 60 minutes/hour) comes from the sexagesimal system, used over 4,000 years ago!
How to Calculate Age in Hours Manually (If You’re Curious)
Want to know how the math works behind the scenes?
- Age in years × 365.25 × 24
- Add days from current year × 24
- Add any additional hours
Too much math? That’s what we’re here for 😉
Our Age in Hours Calculator handles all this instantly—no calculator needed!
Why Are There 24 Hours in a Day?
The 24-hour day originated from ancient Egypt, where sundials were used to divide daytime into 12 hours. Night was also split into 12 “watches.”
Together? That makes 24 hours—still the standard today.
