The French republican calendar, dictated by the National Convention, has had its forerunners. The most important among them was Sylvain Maréchal, a highly original and remarkable figure.
In 1788 Sylvain Maréchal issued the Almanach des Honnêtes Gens, dated “Fan premier de la Raison” (the first year of Reason), in which the names of the days of the week, the Christian festivals and the table of Saints were omitted. It was this almanac, modified in accordance with the circumstances, that served as the prototype for the republican calendar. Maréchal was put into prison, and afterwards exiled from Paris. His calendar was impounded and burnt by order of the Parliament. Later on Maréchal issued other almanacs and fought in the press for the reform of the calendar. All this is dealt with in the present study, and the name of Marechal will forthwith be linked to those of Romme and Fabre d'Eglantine, the two members of the Convention to whom the republican calendar is due.
