Quartidi
The twelve months of the republican calendar of the French Revolution are each divided into three "decades" of ten days. Quartidi is the fourth day of a decade. The 4th, 14th and 24th of each month and the Fête de l'opinion of the Sansculottids fall on a Quartidi.
Day names
The day names of the Quartidi were (like most other day names) agricultural crops. Only in the Nivôse were the days named after minerals and animal substances.
