Переведите текст: Christmas is the main public holiday in Britain and the US. This Christian holy day is held on December 25th (in Russia on January 7th) in honour of the birth of Christ. People often see it as a time of merry-making and present-giving. They usually spend time with their families, eat special food and drink a lot. On Christmas Eve some people go to a special church service called Midnight Mass or Christmas Eve Service at 12 o'clock at night. Others may have a drink with their friends.
