Draft of the senate consultation on the reestablishment of the Gregorian calendar, 29 August 1805, (1921). 'Projet de s?natus-consulte r?tablissement le calendrier gr?gorien'. Document signed by Emperor Napoleon I and dated 'Dec[ade] 12 Fructidor, an 13', dealing with the reintroduction of the Gregorian calendar, replacing the French Republican calendar. Also known as the French Revolutionary calendar, the system was implemented during the French Revolution and used for about 12 years from late 1793 to 1805, (and for 18 days by the Paris Commune in 1871). The intention had been to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France.
