Which of the following festivals includes a celebration that lasts from December 17-23?

The festival that includes a celebration lasting from December 17-23 is Saturnalia. This ancient Roman festival was dedicated to the god Saturn and was characterized by a time of merriment, feasting, and reversal of social norms. During Saturnalia, traditional roles were often upended; for instance, slaves were given temporary freedom and could be treated as equals, fostering a spirit of joy and equality among participants. The festival's extensive duration, coupled with its wide array of customs, such as gift-giving and public celebrations, made it one of the most popular and anticipated events in the Roman calendar.

The other festivals mentioned, such as Vinalia Rustica, Robigalia, and Parilia, occur at different times of the year and celebrate various aspects of Roman agricultural life or gods, which differentiates them significantly from Saturnalia.
