Norwegians celebrate Christmas with a mix of traditional and modern customs, including the decoration of Christmas trees, gift giving, and the exchange of holiday cards and greetings. The main celebration is held on Christmas Eve, when families gather for a traditional dinner, and children open their presents at midnight. The traditional Christmas dinner is served at midday, consisting of roast pork, ribs, and mutton with potatoes and vegetables, followed by a variety of desserts and pastries. Families will also attend church services, where they will sing carols and hear a sermon about the birth of Jesus.
