Christmas is the time when Christians around the world celebrate the birth of Jesus. Every year in December we celebrate the birthday of Jesus Christ. That is why we call this time "Christmas"—we celebrate the "Mass", or church service, for Christ.
Christmas is a truly magical season, bringing families and friends together to share, the much loved customs and traditions which have been around for centuries. Most people are on holiday in England and stay at home with their family on Christmas day. Christmas is celebrated on the 25th of December in England, with a Christmas dinner for the whole family. During the weeks before Christmas Day, we send cards, watch nativity plays and go to carol services. We also decorate our homes and churches with green leaves, Christmas trees, paper decorations and colourful electric lights.
Christmas customs and traditions in England, are gradually being lost. Christmas has also become commercialised and the old meaning of Christmas is too often forgotten.
Nowadays, Christmas is celebrated all over the world in many countries, including China, where it is becoming more and more popular.
