This came into being after the overthrow of the French monarchy. Because of the problems that it created, it lasted for only fourteen years. It dated from September 22, 1792, when the Republic was declared.
The week had ten days, with Latin numerical names. There were twelve months, with descriptive names. The first day of the year coincided with the autumnal equinox. Each month had thirty days. Five intercalary days were added in common years. These days honoured the poor ragged peasants in Paris. In leap years, a sixth day was added at the end of the year. This day was dedicated to sports.
