Tridi
The twelve months of the republican calendar of the French Revolution are divided into three “decades” of ten days. Tridi is the third day of a decade. The 3rd, 13th and 23rd of each month and the Fête du travail of the Sansculottides fall on a Tridi.
Day names
The day names of the Tridi were (like most other day names) agricultural crops. Only in the Nivôse were the days named after minerals and animal substances.
