The
French Republican Calendar , also commonly called the
French Revolutionary Calendar (
calendrier révolutionnaire français) was a
calendar created and implemented during the
French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the
Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France (which also included
decimal time of day,
decimalisation of currency, and
metrication).
