Editing French Republican calendar (section)

=== Precursor ===
The prominent atheist essayist and philosopher [[Sylvain Maréchal]] published the first edition of his ''Almanach des Honnêtes-gens'' (Almanac of Honest People) in 1788.<ref name="Marechal">{{cite book |title=Almanach des Honnêtes-gens |pages=14–15 |first=Maréchal |last=Sylvain |url=http://gallica.bnf.fr/ark:/12148/bpt6k48116c.swf.f3.langFR |via=gallica.bnf.fr |publisher=Gallica |year=1836 |access-date=3 June 2014 |archive-date=3 September 2015 |archive-url=https://web.archive.org/web/20150903224628/http://gallica.bnf.fr/ark:/12148/bpt6k48116c.swf.f3.langFR |url-status=live }}</ref> The first month in the almanac is "Mars, ou Princeps" (March, or First), the last month is "Février, ou Duodécembre" (February, or Twelfth). The lengths of the months are the same as those in the Gregorian calendar; however, the 10th, 20th, and 30th days are singled out of each month as the end of a ''décade'' (group of ten days). Individual days were assigned, instead of to the traditional saints, to people noteworthy for mostly secular achievements. Later editions of the almanac would switch to the Republican Calendar.<ref>{{cite web |title=Almanach des honnêtes gens pour l'an VIII |first=Maréchal |last=Sylvain |url=https://gallica.bnf.fr/ark:/12148/bpt6k97396377.r=?rk=21459;2 |website=gallica.bnf.fr |publisher=Gallica |year=1799 |access-date=19 November 2019 |archive-date=25 May 2020 |archive-url=https://web.archive.org/web/20200525231239/https://gallica.bnf.fr/ark:/12148/bpt6k97396377.r=?rk=21459;2 |url-status=live }}</ref>
