Celebrating the birth of Jesus Christ.  People celebrate Christmas Day in many ways. In the days or even weeks before Christmas Day, many people decorate their homes and gardens with lights, Christmas trees and much more. It is common to organize a special meal, often consisting of turkey and a lot of other festive foods, for family or friends and exchange gifts with them. Children, in particular, often receive a lot of gifts from their parents and other relatives and the mythical figure Santa Claus. This has led to Christmas Day becoming an increasingly commercialized holiday, with a lot of families spending a large part of their income on gifts and food.

Many Sunday schools, churches and communities organize special events. These can include decorating the neighborhood or a shopping mall, putting up a Christmas tree and planning a Nativity display, concert or performance. A lot of plays and songs have a aspect of Christmas as a theme. Some groups arrange meals, shelter or charitable projects for people without a home or with very little money.
