The Sansculottides (; also Epagomènes; ) are holidays following the last month of the year on the French Republican calendar which was used following the French Revolution from approximately 1793 to 1805. The Sansculottides, named after the sans-culottes, append the twelve, 30-day months of the Republican Calendar with five complementary days in a common year or six complementary days in a leap year, so that the calendar year would approximately match the tropical year. They follow the last day of Fructidor, the last month of the year, and precede the first day of Vendémiaire. Each of the Sansculottides were assigned as one of the ten days of the week. Even though the five or six days were less than a full week, the following 1 Vendémiaire would still be a primidi, skipping four or five days of the week. The Sansculottides belong to the summer quarter. They begin on 17 or 18 September and approximately end on the autumn equinox, on 22 or 23 September on the Gregorian calendar. History In the decree of 5 October 1793 (le 14 du 1er mois de l'an II; later: le 14 Vendémiaire de l'an II) by the National Convention, the days following the last month of the year were named jours complémentaires and numbered serially. Only the leap day (jour intercalaire) received a name: 1. premier jour complémentaire — First Complementary Day 2. second jour complémentaire — Second Complementary Day 3. troisième jour complémentaire — Third Complementary Day 4. quatrième jour complémentaire — Fourth Complementary Day 5. cinquième jour complémentaire — Fifth Complementary Day 6. jour de la Révolution — Revolution Day The other days, decades, and months were also serially numbered. On 24 October (le 3 du 2e mois; later: le 3 Brumaire) of the same year, the poet Philippe-François-Nazaire Fabre, known as Fabre d'Églantine, made public his dislike of this naming convention ("le premier jour de la première décade du premier mois de la première année"). He suggested proper names for the months, the days of the months, and the days of the decades. For the jours complémentaires, he introduced the name Sansculottides. The individual days should have the following names: 1. fête du génie — Celebration of Talent 2. fête du travail — Celebration of Labour 3. fête des actions — Celebration of Policy 4. fête des récompenses — Celebration of Honors 5. fête de l’opinion — Celebration of Convictions
