The French Republican Calendar, dividing the month into three "décades" of 10 days each, was introduced during the French Revolution in the decree of 5 October 1793, simultaneously with the decimal time. Although clocks and watches were produced indicating both standard and decimal time and date, the system never caught on and was officially suspended on 7 April 1795.
