existence of non religious calendars

Did any non religious dating systems exist? Were they successful? The French Republican calendar can answer both these questions. The French calendar was created and implemented by the National Convention, specifically under the direction of Charles Gilbert Rome, during the French Revolution. It was used by the French government for twelve years, 1793 to 1805. It was designed to remove all religious and Royalist influences from the calendar and to rid any signs of the ancien regime (the old feudal monarchy). It’s important to note that the calendar may be recognized as the French Revolutionary Calendar because of the different sides and perspectives that labeled it different names. From the royalty point of view, this was seen as treason so they nicknamed it the ‘revoutionary’ calendar. However, on the other hand, the nationalistic, proud creators of the calendar named it the ‘Republican’ calendar. This dating system proved to be unsuccessful because it was abolished by Napolean the first and replaced with the Gregorian calendar. It was, however, used again briefly during the short period of the Paris Commune, 6–23 May 1871. Some legal texts that were adopted when the Republican Calendar was officially in use are still in force in France and other nations or territories which at the time were incorporated into revolutionary France, such as present-day Belgium, Luxembourg and the German territories to the west of the Rhine river. These documents have kept their original dates for legal accuracy and citation purposes.
