A '''decade''' is a period of 10 [[year]]s (since 1594)[http://www.etymonline.com/index.php?term=decade], a [[Decade (log scale)|factor of 10 difference between two numbers]], or sometimes a set or a group of ten (since 1451). It is also a period of 10 days in the [[French Republican calendar]]. The word is derived from the late [[Latin]] "decas", from Greek "dekas", from deka. The other English words for periods of several years also come from Latin: [[lustrum]] (5), [[century]] (100), [[millennium]] (1000).
In English the word can be used to specify a general period of ten years, for example "The last decade was characterized by the rise of the [[Internet]]". A decade may also be a well-defined historical period of ten years in a dating system. In that sense, the first decade of the 20th century indicates a period from January 1, 1901 until December 31, 1910.
