Greek Orthodox Christmas is celebrated on January 6th. It's known as "Agios Vasilios," or "Saint Basil's Day." In some parts of Greece, it's also called "Little Christmas" or "Theophany." On this day, families exchange gifts, attend church services, and enjoy a festive meal. In some regions, it's traditional to serve a special dish called "Vasilopita," a sweet bread baked with a coin inside. Whoever finds the coin in their slice is believed to be blessed with good luck for the coming year.
