This is the day when many people are travelling home to do with their families on Christmas Day, 25th December. For most British family, this is the most important festival of the year. There are a lot of traditions connected with Christmas, but perhaps the most important one is the giving of presents. Family members wrap up their gifts and leave them at the bottom of the Christmas tree to be found on Christmas morning. Children leave a long sock or stocking at the end of the Christmas Eve, 24th December, hoping that Father Christmas will come down the chimney during the night and bring them small presents, fruits and nuts. They are usually not disappointed. At some time on Christmas Day the family will sit down to a big turkey dinner followed by Christmas pudding. They will probably pull a cracker with another member of the family. It will make a loud crack and a colored hat, small toy and joke will fall ant. Later in the afternoon they may watch the Queen on television as she delivers her traditional Christmas message to the United Kingdom and the Commonwealth. If they have room for even more food they may enjoy a piece of Christmas cake or eat a hot mince pie. 26th December is also a public holiday, Boxing Day, and this is the time to visit friends and relatives or watch football. Which day is the Christmas Day?
