Did you know that during the French Revolution (in the 1790’s) the French used a new Revolutionary calendar to replace the regular (Gregorian) calendar?
Calculated from 22 September 1792, the day the new Republic was first proclaimed, The Revolutionary calendar had 12 months of 30 days, plus 5 or 6 leap days (with a rule for leap years). It consisted of ten day weeks and twelve months of thirty days. There were five or six feast days at the end of each year dedicated to vacations and celebrations.
The years were numbered starting with the revolution, Year 1. Each of the days were named after various elements from daily life. Days ending in 5 were named after an animal , Days ending in 0 were named after a tool and all other days were named after a plant or mineral.
For example, the 22nd of October (called Brumaire) was named after an apple and the 25th of March was a Poule (a Hen). Unfortunately, if you were born on the 29th December, you were born on the day of Fumier, or Manure.
The French Revolutionary calendar was used from 1793 through 1805 when Napoleon decided the country (and areas under French rule) should go back to the Gregorian calendar on December 31.
