Tucindan is a religious and folk festival observed in Serbia and Montenegro on January 5. The name Tucindan is derived from the verb "tući," meaning "to beat," and it has pagan roots that were later adopted by the church, with Saint Sava believed to have introduced it as a religious holiday. The festival is celebrated on Christmas Eve and features unique traditions, including the roasting of a pig, sheep, or goose, known as pečenica, which is prepared by feeding the chosen animal better fodder for one or two months prior to the holiday. On Tucindan, the animal is killed in a specific manner, and its blood is mixed with fodder to be given to cattle, as it is believed this practice promotes their thriving. Additionally, a notable custom during Tucindan is that children are not punished for misbehavior, as it is thought that doing so would lead to them being naughty for the entire year.
