In depth
Each month was divided into three ten-day décades. The poet Fabre d'Églantine named the months, and the politician Gilbert Romme, the mathematician Lagrange and the astronomer Lalande were among its designers. Autumn has Vendémiaire, Brumaire and Frimaire; winter Nivôse, Pluviôse and Ventôse; spring Germinal, Floréal and Prairial; summer Messidor, Thermidor and Fructidor. Revolutionary events and laws are often named by dates in this calendar, such as 9 Thermidor (27 July 1794), the Law of 22 Prairial (10 June 1794) and the coup of 18 Brumaire (9 November 1799). It was briefly revived during the Paris Commune of 1871.
