The English term is still often used popularly to indicate the games themselves, a usage that is uncommon in ancient Greek (as an Olympiad is most often the time period between and including sets of games). It is also used to indicate international competitions other than physical sports. This includes international science olympiads, such as the International Geography Olympiad, 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, International History Olympiad and Computer Olympiad. In these cases Olympiad is used to indicate a regular event of international competition for top achieving participants; it does not necessarily indicate a four-year period.
In some languages, like Czech and Slovak, Olympiad (Czech: olympiáda) is the correct term for the games.
The Olympiad (L'Olimpiade) is also the name of some 60 operas set in Ancient Greece.
