The document discusses the introduction of the revolutionary calendar in France during the late 18th century. It was implemented by the National Convention in 1793 in an attempt to replace the Gregorian calendar and reduce the influence of Christianity. Key reasons for introducing the new calendar were to eliminate religion from daily life by removing references to Christian holidays and saints days, and to increase the number of working days for peasants. However, the calendar was unpopular with the general public and government officials and was replaced under Napoleon I due to this lack of acceptance.
