876,000

A century is one of the grandest measures of time — 100 years of progress, change, and history.
From revolutions and inventions to entire generations being born and gone, a century holds countless hours that shape human civilization.

But have you ever wondered:
👉 Exactly how many hours are in a century?
Let’s calculate it and explore why understanding time at this scale is so fascinating.

Quick Answer

There are approximately 876,000 hours in a century.
Here’s how we get that number:

1 year = 365 days (or 365.25 for leap years)
1 day = 24 hours
100 years × 365.25 × 24 = 876,600 hours

So, a century = 876,000 to 876,600 hours, depending on how leap years are counted.
