fun fact: Thermidor - after which Sauce Thermidor and derived dishes like Lobster Themidor are named, is a month in the French Republican Calendar, specifically: the second month of summer, going approx. from mid-July to mid-August.

Neil Gaiman who introduced me to the French Republican Calendar in a story set during the French revolutionary period (The Sandman #29). I didn’t have easy access to an encylopedia (or the Internet) in the early nineties so Thermidor was the only month I knew for a long time.

Even more fun fact. "Thermidor" as well as the other months on the Republican Calendar don't have any root word. They were made up whole cloth and intended to sound like Greek or Latin.

Even more fun fact: 9 Thermidor Year II is also when Robespierre was ousted and his reign of terror ceased. He would be executed the next day.

This Republican calendar is also a source of headaches for students studying the French Revolution because while it didn’t stick, it stuck around long enough to matter and for historians to need to deal with it in primary sources.

That may be true for other months, but "therme" is Greek for heat and Thermidor would be the hottest month of the calendar.
