Republic Proclaimed: France Abolishes Monarchy

France didn't just overthrow its king — it tried to overthrow time itself. The new Republic scrapped the Gregorian calendar entirely, declared Year One, renamed the months after weather and harvests, and split each week into ten days instead of seven. Today was Primidi Vendemiaire: first day of the grape harvest month. The system lasted twelve years before Napoleon quietly killed it. But for one generation of Frenchmen, history itself had a new start date. The French Republican Calendar was designed by mathematician Charles-Gilbert Romme and poet Philippe Fabre d'Eglantine, who replaced saints' days with names of plants, animals, and tools. Brumaire was fog month. Thermidor was heat month. Fructidor was fruit month. Each month had exactly thirty days, divided into three ten-day weeks called decades, which meant workers got one day off in ten instead of one in seven. Nobody liked that part. The names were elegant on paper but impossible in practice. International trade required constant conversion between French and Gregorian dates. Catholic France resented losing its Sundays and feast days. The calendar's decimal logic extended to the clock as well, with each day divided into ten hours of one hundred minutes each, though decimal time was abandoned even faster than the calendar. Napoleon formally restored the Gregorian calendar on January 1, 1806, recognizing that revolutionary zeal couldn't override the practical needs of a continental empire. But the calendar lives on in history books: the Thermidorian Reaction, the 18 Brumaire, Germinal — French revolutionary events are still known by their Republican calendar dates.
