Christmas in Iceland
Christmas traditions in Iceland is worth the experience. The Icelandic Christmas culture is loaded with native old Icelandic traditions. Iceland is a real treat for children at Christmas when no less than 13 Santa Clauses (jólasveinn) come to town bearing food and gifts on Christmas Eve. Each of the santa clauses has its own name, character and role. Their parents are Grýla, a mean old woman who drags off naughty children, and Leppalúði, who is not as mean. There is also a tradition known as "Shoe in the Window" that begins on the evening of December first when all the children in Iceland place their best shoe in their bedroom window before they go to sleep. If' they have been good that day, they  receive a special treat in their shoe from Santa Clause. This continues every day until Christmas. Other than these customs the holiday is celebrated in much the same way as elsewhere around the world with the exchange of gifts and a festive meal, often ptarmigan, a game bird, or smoked lamb, eaten on Christmas Eve.
The mass day of St. Thorlakur (Thorlaksmessa) is celebrated on 23rd of December. Shops are open until 23:30 and then close for three days during Christmas. Many attend midnight mass. The Christmas season lasts 26 days.
