In the republican Calendar (or revolutionary calendar), the franciade is the four years period at the end of which it is necessary to add one day to the calendar year so that it remains aligned with the tropical year (~365 ¼ days).

The franciade was defined in 1793 in article ten of the Decree of national Convention over the Era, the beginning and the organization of the Year, and on the names of the Days and the Months, as follows:

“ period the four years, at the end of which this one day addition is usually necessary, is called the franciade, in memory of the revolution which, after four years of efforts, led France to the republican government. ”

The day added at the end of the complementary days is called then the “day of the revolution”.

Franciade was also the name given to Saint-Denis (Seine-Saint-Denis) of 1793 to 1800.
