In the UK, Christmas is celebrated with families exchanging gifts under Christmas trees on December 25th. Decorating the tree is a family tradition, and homes are also decorated with holly, ivy, and mistletoe. Nativity plays and carol services are held in churches. Children believe Santa Claus leaves gifts in stockings or pillowcases overnight on Christmas Eve. The traditional Christmas meal is roast turkey with trimmings eaten in the afternoon on Christmas Day, and trifle is a popular dessert. New Year's Eve, called Hogmanay in Scotland, is celebrated with fireworks displays in cities across the UK including London and Edinburgh.
