Calendrier Républicain

This is a converter from the commonly used Gregorian Calendar to the French Republican Calendar.

It currently only implements the Romme System for recent dates, meaning that it has a shift of one day for sextile years before the year 20 (1811).

History

The French Republican Calendar (French: calendrier républicain français), also commonly called the French Revolutionary Calendar (calendrier révolutionnaire français), was a calendar created and implemented during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France (which also included decimal time of day, decimalisation of currency, and metrication).
