APPENDIX.
THE FRENCH REVOLUTIONARY CALENDAR.
This calendar, established by the First Republic, went into effect by retroaction
on September 22, 1792, having been legally adopted on November 24, 1793. It
was abolished December 31, 1805. The year consisted of twelve months of thirty
days each; five, and in leap years six, supplementary days (sans-culottides) were
added to bring the number of days up to 365 and to 366 respectively. Each set of
four years was called a franciade. Each month was divided into periods (decades)
of ten days each, the week having been abolished; the tenth day was a day of rest.
The year beginning September 22, 1792, was the year I (Van I) of the Republic.
