The term is still often used popularly to indicate the games themselves, a usage that is strictly erroneous (as an Olympiad is the time period between games) but widely accepted nevertheless. It is also used to indicate international competitions other than physical sports. This includes international science olympiads, such as the International Mathematical Olympiad and the International Linguistics Olympiad and their associated national qualifying tests (e.g., the United States of America Mathematical Olympiad or the North American Computational Linguistics Olympiad), and also events in mind-sports, such as the Science Olympiad, Mindsport Olympiad, Chess Olympiad and Computer Olympiad. In these cases Olympiad is used to indicate a regular event of international competition; it does not necessarily indicate a four-year period.
The Olympiad (L'Olimpiade) is also the name of some 60 operas, of which the plot is set in Ancient Greece.
