Overview
Thermidor was the eleventh month in the French Republican Calendar. The month was named after the French word thermal, derived from the Greek word "thermos" (heat).
Thermidor was the second month of the summer quarter (mois d'été). It started July 19 or 20. It ended August 17 or 18. It follows the Messidor and precedes the Fructidor. During Year 2, it was sometimes called Fervidor.
Because of the Thermidorian Reaction—9 Thermidor Year II—the overthrow of revolutionary radical Maximilien Robespierre and his followers in that month, the word "Thermidor" has come to mean a retreat from more radical goals and strategies during a revolution, especially when caused by a replacement of leading personalities.
Day name table
Like all French Republican Calendar months, Thermidor lasted 30 days and was divided into three 10-day weeks called décades (decades). Every day had the name of an agricultural plant, except the 5th (Quintidi) and 10th day (Decadi) of every decade, which had the name of a domestic animal or an agricultural tool, respectively.
