Christmas traditions vary from culture to culture. Finns often visit saunas on Christmas Eve, while Portuguese revelers hold a feast on Christmas Day for the living and the dead (extra places are set for the souls of the deceased). In Greece, some believe that goblins called kallikantzeri run wild during the 12 days of Christmas, and most Greeks don't exchange presents until Jan. 1, St. Basil's Day. Thanks to their geographic location, most Australians and New Zealanders enjoy Christmas on the beach or at barbecues. Spain, meanwhile, hosts the world's largest lottery.
