howlong is a century

A century is 100 years long.

Quick Scoop

  • A century = 100 years.
  • That’s also:
    • 10 decades (since a decade is 10 years).
* About 1,200 months.
* About 36,524 days in the Gregorian calendar.

In simple terms: if you were born at the start of a century and lived the entire century, you’d celebrate your 100th birthday as that century ends.

TL;DR: howlong is a century → 100 years, or ten decades.
