Christmas is a holiday observed in much of the world on 25 December (or on 7 January in most Eastern Orthodox Churches). It is celebrated by most Christians to mark the birth of Jesus, although in the U.S and Europe it has slowly become more of a secular holiday. Jesus is believed to have been born around the period of 1 BC, in Bethlehem, Jerusalem in an old stable alongside his mother Mary and her husband Joseph.

In Western countries, Christmas has become the most economically significant holiday of the year. It is largely characterized by gifts being exchanged between friends and family members.

The word Christmas is a contraction of Christ's Mass, derived from the Old English Cristes m�sse. It is often abbreviated Xmas, probably because X resembles the Greek letter Χ (chi) which has often historically been used as an abbreviation for Christ (Χριστός in Greek). 

Christmas Tree: There have also been many legends surrounding the lore of the Christmas tree. In one story Saint Boniface, an English monk, came upon a group of pagans who had gathered around an oak tree and were preparing to sacrifice a child. To stop the sacrifice and save the child, the Saint flattened the oak tree with one blow of his fist. A small fir sprang up in its place, which Saint Boniface told the pagans was the Tree of Life and represented the life of Christ.

The early 20th century saw Americans decorating their trees mainly with homemade ornaments, while the German-American sect continued to use apples, nuts, and marzipan cookies. Popcorn joined in after being dyed bright colors and interlaced with berries and nuts. Electricity brought about Christmas lights, making it possible for Christmas trees to glow for days on end. With this, Christmas trees began to appear in town squares across the country and having a Christmas tree in the home became an American tradition.

A beautifully decorated evergreen tree, with colored lights ablaze inspires in many warm memories of Christmases long past. The Christmas tree has become one of the most beloved and well know holiday symbols. 

The custom of gift-giving on Christmas dates only to Victorian times. Before then it was more common to exchange gifts on New Year's Day or Twelfth Night. Santa Claus is known by British children as Father Christmas. Father Christmas, these days, is quite similar to the American Santa, but his direct ancestor is a certain pagan spirit who regularly appeared in medieval mummer's plays. The old-fashioned Father Christmas was depicted wearing long robes with sprigs of holly in his long white hair. Children write letters to Father Christmas detailing their requests, but instead of dropping them in the mailbox, the letters are tossed into the fireplace. The draft carries the letters up the chimney, and theoretically, Father Christmas reads the smoke. Gifts are opened Christmas afternoon.

The hanging of greens, such as holly and ivy, is a British winter tradition with origins far before the Christian era. Greenery was probably used to lift sagging winter spirits and remind the people that spring was not far away. The custom of kissing under the mistletoe is descended from ancient Druid rites. The decorating of Christmas trees, though primarily a German custom, has been widely popular in England since 1841 when Prince Albert had a Christmas tree set up in Windsor Castle for his wife Queen Victoria, and their children.

The word "wassail" is derived from the Anglo-Saxon phrase waes hael, which means "good health." Originally, wassail was a beverage made of mulled ale, curdled cream, roasted apples, nuts, eggs, and spices. It was served for the purpose of enhancing the general merriment of the season. Like many of the ancient customs, "wassailing" has a legend to explain its origin. It seems that a beautiful Saxon maiden named Rowena presented Prince Vortigen with a bowl of wine while toasting him with the words "Waes hael." Over the centuries a great deal of ceremony had developed around the custom of drinking wassail. The bowl is carried into a room with great fanfare, a traditional carol about the drink is sung, and finally, the steaming hot beverage is served.

For many years in England, a roasted boar's head has been associated with Holiday feasting. The custom probably goes back to the Norse practice of sacrificing a boar at Yuletide in honor of the god Freyr. One story tells of a student at Oxford's Queen College who was attacked on Christmas Day by a wild boar. All he had in his hand to use as a weapon was his copy of Aristotle, so he shoved the book down the boar's throat. Wanting to retrieve his book, the student cut off the animal's head and brought it back to the college where it was served for Christmas dinner with much pomp and ceremony.

The custom of singing carols at Christmas is also of English origin. During the middle ages, groups of serenades called "waits" would travel around from house to house singing ancient carols and spreading the holiday spirit. The word "carol" means "song of joy." Most of the popular old carols we sing today were written in the nineteenth century.

The celebration of Boxing Day, which takes place on December 26 - the feast of St. Stephen, is a part of the holiday season unique to Great Britain. Traditionally, it is on this day that the alms box at every English church is opened and the contents are distributed to the poor. Also, this is the day that servants traditionally got the day off to celebrate with their families. It became traditional for working people to break open their tip boxes on this day. Boxing Day began in the mid-nineteenth century when the custom of tipping by rich persons to persons in service positions had apparently gotten out of hand. Children and others pretended to be in the trades and solicited tips. The custom was expanded to giving to anyone and everyone who had less money than you did, and soon the streets at Christmastime were full of aggressive soliciting of tips. To contain the nuisance "Boxing Day" was designated as the one day for giving to the less fortunate.
