The calendar system in France has been changed several times. However, of those used in the last three hundred years, the French Republican Calendar is the most challenging for the researcher. You may also see it referred to as the French Revolutionary Calendar. When it was created and implemented by the Republic some records were backdated to the beginning of the French Republic on 22 September 1792, which was designated as the start of year 1 of the Republican Calendar.
The revolutionaries divided the year into twelve thirty-day months and named those months for occurrences in nature within those time frames. They then added five days at the end of the year that were made into feast days for the Republic. A leap year was supposed to occur every four years that had six end-of-the-year feast days. The first year beginning September 22, 1792 was designated as An 1, the next An 2, and so forth. This calendar only lasted for 13 years, from 1792 to 1806 when France, under Napoleon, returned to the Gregorian calendar used elsewhere in Europe. (For the month of May 1871 the Commune in Paris readopted the Republican Calendar.)
Months of the year in the Republican Calendar were:

A researcher will need to know how dates were recorded under the Republican Calendar. They were usually written out in French or the local language in Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, and Italy, as well as other areas ruled by the French government, such as Egypt, Malta, Reunion, Louisiana, Guiana, and some Caribbean islands. For example:
The years of the Republic were often designated by Roman numerals. For example:
