Nonidi
The twelve months of the republican calendar of the French Revolution are each divided into three "decades" of ten days. Nonidi is the ninth day of a decade. The 9th, 19th and 29th of each month fall on a nonidi.
Day names
The day names of the Nonidi were (like most other day names) agricultural crops. Only in the Nivôse were the days named after minerals and animal substances.
