This library is a gregorian to republicain date converter.

The French Republican Calendar (🇫🇷 Calendrier Républicain Français) or French Revolutionary Calendar (🇫🇷: Calendrier Révolutionnaire Français), was a calendar created during the French Revolution and used by French governments for about 12 years from 1793 to 1805. Read more about Republican Calendar in the dedicated article.

This converter interpolates the Revolutionary Calendar after it was abolished in 1805 until nowadays and to future.
