Decade – how many years is it?

One decade, how many years is that? This question is often asked in history books as well as in various game shows and quizzes. Let’s clarify.

How many years is a decade?

It is worth noting that the word “decade” has the prefix “deka” at the beginning. This is a word derived from Greek and it means a multiplier of 101, or simply “ten of something”. In the case of years, a decade simply refers to a period of 10 years.

Other “decades” – month and century

As a supplement, it is also worth adding that there are decades within a month, as well as decades within a century. The former, decades within a month, divide the month into periods of 10 days. Decades within a century, on the other hand, divide the entire century into 10-year periods.
