Decimal Calender

Decimal Calender Also called Revolutionary or Republican Calander, The calendar system which includes units of time based on the decimal system. It was implemented during the French Revolution in the late 18th century. It aimed to replace the traditional Gregorian calendar with a decimal-based system, aligning it with the principles of the French Revolution, which emphasized rationality and decimalization.


Under the Revolutionary calendar, time was divided into 10-hour days, with each hour consisting of 100 minutes, and each minute divided into 100 seconds. This decimal time system sought to simplify timekeeping and promote a more logical and consistent approach to measuring time.

While the Revolutionary calendar was officially adopted in France for a brief period, it did not gain widespread acceptance and was eventually discontinued.
