The Festival of Good Luck was celebrated on April 5th in Ancient Rome.
Fortuna, also known as Fors Fortuna (equivalent to the Greek goddess Tyche), was the goddess of fate, change, fortune, and the personification of luck in Roman religion. She had different aspects such as Fortuna Annonaria for the luck of the harvest, Fortuna Belli for the fortune of war, and Fortuna Romana for the fortune of Rome.
April 5 honors Fortuna Publica, fortune of the people.
In Rome, most festivals included ludi (games) and religious ceremonies. Businesses closed for the day and slaves were given a break from labor.
