The logically-minded men of the French Revolution devised decimal systems of weights and
measures and of currency, so why not a decimal calendar too? This project was
entrusted to a group of mathematicians, scientists and a couple of poets by the
Committee of Public Safety in late 1792, and next autumn the group’s proposals
were implemented.
The new era
was proclaimed to have begun on September 22nd 1792, when France
became a republic: the start of Year One of the new calendar. Much propaganda was made of the
coincidence with the autumn equinox: all Frenchmen became equal at the same
time as day and night were equal!
The year was
to be made up of 12 months (even they couldn’t escape from this magic number!)
each of 30 days. There were to be 5 extra days, “Festival days” outside the
normal months, with a sixth added in leap years (the first of these being in
Year III). To replace the weeks, each month was to have 3 decades of 10 days
each; with a day divided into 100 minutes, and a minute into 100 seconds. There
would thus be 100,000 seconds in a day, instead of 86,400 under the old system.
Watchmakers were ordered to start making new watches for these new
arrangements, and many of these survive.
The new days
were prosaically named 1st, 2nd, etc, but the festival
days were all given their own individual names, and a not-very-successful poet, Philippe
Fabre d’Eglantine, was given the job of devising names for the new months. He
decided to name them after climatic and agricultural themes (starting on September 22nd):-
Vendemiaire,
Brumaire, Frimaire, Niviose, Pluvoise, Ventose, Germinal, Floreal, Prairial,
Messidor, Thermidor, Fructior.
meaning,
roughly:-
Vine-harvest,
Foggy, Frosty, Snowy, Rainy, Windy, Budding, Flowers,
Meadow-grass,
Reaping, Hot, Fruit.
Fabre’s
names won official acceptance, but he did not enjoy his success for long. He
was a close friend of the radical leader Danton, and when Danton’s group was
purged by Robespierre in spring 1794, Fabre followed his leader to the
guillotine.
The revolutionary
calendar lasted a little longer. Napoleon Bonaparte staged a military coup in
Brumaire 1799. In 1804 he crowned himself Emperor and sought a reconciliation
with the Catholic Church, as a result of which Sunday was restored as a day of
rest and the Gregorian calendar reinstated on January 1st 1806.
There have been no serious attempts to reform the calendar since then. Even
suggestions to set a fixed date for Easter have invariably failed!
