The encyclopedia entry (Americana, Canadian Edition 1960) contains its own how to instructions. How to build a table to illustrate seasons and months.
Revolutionary Calendar, a calendar adopted during the French Reign of Terror. It was decreed on Nov. 24, 1793, to commence from the foundation of the French republic, Sept. 22, 1792. The 12 months were Vendémiaire, Brumaire, Frimaire, Nivose, Pluviose, Ventose, Germinal, Floréal, Prairial, Mesidor, Fervidor or Thermidor, and Fructidor. The first three constituted autumn, the second three winter, the third spring and the fourth three summer. Napoleon I restored the old system Dec. 31, 1805.
Notice how the entry writer avoids “third three”.
- Vendémiaire, Brumaire, Frimaire
- Nivose, Pluviose, Ventose
- Germinal, Floréal, Prairial
- Mesidor, Thermidor, Fructidor
I like how the suffix indicates season. And no traces of Roman emperors (July and August).
And so for day 352
