A Solemnity of the Roman Catholic Church observes an event in the life of Jesus, Mary, and the saints, beginning on the evening prior to the actual date. Solemnity is made up of Latin words solet and annus, meaning a yearly (annual) celebration. They are observed throughout the entire Church. Feasts, on other hand, are celebrated on the actual date.
