| This calendar was used for twelve years, from '''24 October 1793 to 31 December 1805.''' (An attempt was made in 1871 to reinstate it, but this attempt failed.) However, it was back-dated to have begun on 22 September 1792. It was used for civil registration records, notarial records, and other government records throughout France and other areas under French rule, including modern Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, and Italy. It also affected records in other areas ruled by the French government, such as Egypt, Malta, Reunion, Louisiana, Guiana, and some Caribbean islands. | | This calendar was used for twelve years, from '''24 October 1793 to 31 December 1805.'''
