Usage notesEdit

Although a decade may refer to any group of ten years, it often particularly refers to the informal ten-year periods of the calendar whose last digits run from 0 to 9. Some style guides may prefer that decade refers exclusively to such calendar periods while decennium, decennary, &c. refers to ten-year periods in other contexts.

It should be noted that the method of computing a decade is distinguished from the proper computation of centuries and millennia, which run from 1 to 0. The 1st century began with the year 1 and ended with the year 100, but "the Nineties" are the years whose name includes the word ninety, from '90 to '99 with all those years with a 9 in the tens place digit.
