Saturnalia Was a One-week Festival
Even though it began as a celebration of just one day, it soon proved so popular among the Romans that it ended up being celebrated for an entire week. Starting as a one-day holiday on December 17th, it then came to be a three-day, and finally one-week festival, ending on December 23rd. The Romans realized that the moments when they were enjoying themselves should last a bit longer. Saturnalia was an opportunity for people to relax, forget about their liabilities, celebrate their good fortune, eat good food, and have great sex.
