1. The fourth month of the French revolutionary calendar, extending (in 1793 to 1794) from 21 December to 19 January; literally, "month of snow"; coined by Fabre d'Églantine in 1793.
2. The month was named after the Latin word nivosus, meaning "snow, snowy".

According to Fabre d'Églantine: "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."

The poet Fabre d'Eglantine created poetic names for the months to match the seasons in which they occurred:

1. Vendémiaire, vintage month
2. Brumaire, fog month
3. Frimaire, sleet month
4. Nivôse, snow month
5. Pluviôse, rain month
6. Ventôse, wind month
7. Germinal, seed month
8. Floréal, blossom month
9. Prairial, pasture month
10. Messidor, harvest month
11. Thermidor, heat month
12. Fructidor, fruit month
13. Sansculottides, additional days

Within the decade sections of the calendar, the days were given names with respect to their positions:

1. primidi
2. duodi
3. tridi
4. quartidi
5. quintidi
6. sextidi
7. septidi
8. octidi
9. nonidi
10. décadi
