While researching a topic, a student has taken the following notes:
- The French Republican calendar was used in France from 1793 to 1805.
- Each calendar week had ten days, two of which were called quintidi and decadi.
- Each quintidi was given a unique name in honor of an animal.
- Each decadi was given a unique name in honor of an agricultural tool.
- Bœuf, a quintidi in the month of Vendémiaire, was named after the ox.
- Van, a decadi in the month of Nivôse, was named after the winnowing fan.
