| There are two ways of thinking about when a century begins and ends. The "strict" viewpoint counts centuries from −01 to −00, while the "popular" viewpoint counts centuries from −00 to −99. For example, the "first decade of the 19th century" may mean either 1801–1810 (if used in "strict" terms) or 1800–1809 (if used in "popular" terms). See [[century]] for more information.
