Like all months in the French Republican Calendar, Nivôse lasted 30 days and was divided into three 10-day weeks called décades (decades). The 5th (Quintidi) day of every decade was named after a domestic animal, the 10th day (Decadi) after an agricultural tool (Decadi). Different from the other months the rest of the days were not named after an agricultural plant, but after a mineral or animal substance. Fabre d'Églantine says about this topic:
"In Nivôse earth is sealed and usually covered with snow. At this time earth is resting and there are no herbal agriculture products to characterize this month. We rather took names of animal and mineral substances of agricultural use."
