## What other words are used to describe time?

In addition to understanding the durations of a decade and a century, you should study other terminology used to denote years or different intervals of time. These are used to describe years since it isn’t possible to say that something happened 3289838683908 years ago. Although no specific date is associated with these phrases, they are still used, particularly by anthropologists, historians, and paleontologists.
