French Revolutionary Calendar

The French Revolutionary Calendar was created during the French Revolution to replace the Gregorian calendar. Introduced in 1793, it aimed to reflect revolutionary ideals by dividing the year into 12 months of 30 days each, named after natural and seasonal elements, with five or six extra days added for celebrations. The months were grouped into four seasons, and weeks were reduced to ten days called "décades" to promote rational timekeeping and diminish religious influences. The calendar was used officially in France until 1806, but it never gained widespread adoption and is now mainly of historical interest.
