Decadary Cult
The Decadary Cult (French: Culte décadaire), also called the Cult of the décadi or Tenth-day Cult, was a semi-official religion of France during the Directory period of the French Revolution, intended as a dechristianised replacement of the Christian Sunday worship with a quasi-religious festival on the day of rest in the 10-day week of the French Republican Calendar. The Decadary Cult was a system of worship based on festivals, so-called fêtes décadaires, which were celebrated every décadi, the day of rest in the 10-day week of the Republican calendar.
