What two holidays are mentioned in the passage?

People usually celebrate special occasions by preparing special food. Families may  prepare traditional dinners for holidays such as New Year’s and Thanksgiving. Birthdays and other special days arc often times for baking special cakes. Even celebrations famous only in small areas, such as memorial days for a place or event, can be a time for proud cooks to show off the food that they make the best. Sometimes this food may seem a little strange to the rest of us.
     Weddings are celebrations where food is often an important part of the ceremony or party. Of course, the kinds of food prepared for weddings are different all around the world. One kind of food enjoyed at weddings in the Middle East and some parts of North Africa by members of the Bedouin tribe is roasted camel. This food is not easy to prepare, but when people want to go all out for the wedding, they ask the whole tribe to help with the effort. Tribe members first cook an egg mixture which they then put inside cooked fish. These fish are then put inside several cooked chickens. The chickens then get put into roasted sheep. Usually one or two sheep will be enough to fill one roasted camel. One roasted camel serves 20 to 30 people, so this dish may be enjoyed by the entire tribe at the wedding.
