Although decade may be taken as any group of ten years, it is commonly restricted to the informal ten-year periods of the calendar whose last digits run from 0 to 9. In such contexts, decade refers to such calendar periods while decennium, decennary, &c. refers to ten-year periods in other contexts.
The period of a decade should be distinguished from centuries and millennia, which properly run from 1 to 0. That is, the 1st Century began in the year 1 and ended in the year 100, but "the Nineties" are the years whose name includes the word ninety, from '90 to '99.
- (10-year period; in some contexts): See decennium
