Feria
（重定向自Feriae）
A feria (Latin for "free day") was a day on which the people, especially the slaves, were not obliged to work, and on which there were no court sessions. In ancient Rome the feriae publicae, legal holidays, were either stativae ("fixed," that is, recurring regularly, such as the Saturnalia), conceptivae (movable), or imperativae (appointed for special occasions).
