Greek Christmas is celebrated on January 6th, also known as Epiphany or Three Kings' Day. It's a day of celebration and feasting to mark the end of the Christmas season. The day is dedicated to the arrival of the three wise men, also known as the Magi, who traveled to Bethlehem to pay homage to Jesus Christ. In Greek culture, this day is considered just as important as Christmas Day itself, with traditions such as the cutting of the Vasilopita, or St. Basil's cake, and the blessing of the waters and the fields.
