Was the 7th Day Sabbath Changed to Sunday or Done Away With

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). It was used in government records in France and other areas under French rule, including Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, Malta, and Italy.

The month is divided into three décades or "weeks" of ten days each, named simply:

primidi (first day)
duodi (second day)
tridi (third day)
quartidi (fourth day)
quintidi (fifth day)
sextidi (sixth day)
septidi (seventh day)
octidi (eighth day)
nonidi (ninth day)
décadi (tenth day)
Décadis became official days of rest instead of Sundays, in order to diminish the influence of the Catholic Church. They were used for the festivals of a succession of new religions meant to replace Catholicism: the Cult of Reason, the Cult of the Supreme Being, the Decadary Cult, and Theophilanthropy. Christian holidays were officially abolished in favor of revolutionary holidays.

The law of 13 Fructidor year VI (August 30, 1798) required that marriages must only be celebrated on décadis. This law was applied from the 1st Vendémiaire year VII (September 22, 1798) to 28 Pluviôse year VIII (February 17, 1800).

Décades were abandoned at the changeover from Germinal to Floréal an X (20 to 21 April 1802), after Napoleon's Concordat with the Pope
