Greece celebrates Christmas as its biggest religious holiday. The Orthodox Christian tradition involves fasting from meat and dairy starting in mid-November until Christmas Day. Families decorate their homes with Christmas trees and boats, as Greece is a nautical country. Cities also decorate extensively and hold festivals and events. Traditional Greek sweets baked for the holiday include melomakarona, kourabiedes, baklavas, and kataifi. On Christmas Eve, children sing carols and receive money and sweets door-to-door. The day's big meal typically includes pork dishes to break the fast. Sweets are also given as gifts and enjoyed communally.
