Saint Basil's Day is celebrated on January 1st in many Christian traditions, particularly in the Eastern Orthodox Church. It honors Saint Basil the Great, a 4th-century bishop known for his contributions to Christian monasticism and theology. The day marks the beginning of the new year in the Byzantine calendar and is a time for reflection and celebration. In some cultures, particularly in Greece, people celebrate with special meals and the tradition of cutting a Vasilopita, a cake that contains a hidden coin. The person who finds the coin is believed to receive good luck for the year ahead.
