    • What Are The First Two Decades called?

    At first glance, it all looks logical and straightforward. Decades—periods of ten years—begin when the year count ticks over from a year ending with 9 to a year ending with 0. For example, New Year's Day1980 marked the beginning of the eighties. After all, they are called “the eighties” and not “the eighty-ones,” right?

We don't think twice about using terms like the seventies, the eighties, and the nineties—but what comes next? In recent years, the English speaking world has pretty much settled on a name for the period from 2000 to 2009, but there are regional va...
