Christmas is an annual holiday that celebrates the birth of Jesus. Christmas festivities often combine the commemoration of Jesus' birth with various secular customs. The date as a birthdate for Jesus is traditional, and is not considered to be his actual date of birth.

In most places around the world, Christmas Day is celebrated on December 25. Christmas Eve is the preceding day, December 24.

The word "Christmas" is a contraction of two words "Christ's mass" and is derived from the Middle English Christemasse and Old English Cristes mæsse, a phrase first recorded in 1038. In early Greek versions of the New Testament, the letter Χ (chi), is the first letter of Christ (Χριστός). Since the mid-16th century Χ, or the similar Roman letter X, was used as an abbreviation for Christ. Thus, Xmas is an abbreviation for Christmas.

After the conversion of Anglo-Saxons in England from their indigenous Anglo-Saxon polytheism (a form of Germanic paganism) in the very early 7th century, Christmas was called geol, which was the name of the native Germanic pre-Christian solstice festival that fell on that date. From geol, the current English word Yule is derived. Many customs associated with modern Christmas were derived from Germanic paganism.

The prominence of Christmas Day increased gradually after Charlemagne was crowned on Christmas Day in 800. Around the 12th century, the remnants of the former Saturnalian traditions of the Romans were transferred to the Twelve Days of Christmas (26 December - 6 January). Christmas during the Middle Ages was a public festival, incorporating ivy, holly, and other evergreens, as well as gift-giving.

Modern traditions have come to include the display of Nativity scenes, Holly and Christmas trees, the exchange of gifts and cards, and the arrival of Father Christmas or Santa Claus on Christmas Eve or Christmas morning. Popular Christmas themes include the promotion of goodwill and peace.

History

Pre-Christian origins
A winter festival has been a traditional festival in many cultures due to the winter solstice.In part, the Christmas celebration was created by the early Church in order to entice pagan Romans to convert to Christianity without losing their own winter celebrations. Most of the most important gods in the religions of Ishtar and Mithra had their birthdays on December 25. Various traditions are considered to have been syncretised from various winter festivals.

Christian origins
 
Origen, a father of the Christian church, argued against the celebration of birthdays, including the birth of Christ.It is unknown exactly when or why December 25 became associated with Christ's birth. The New Testament does not give a specific date.[4] Sextus Julius Africanus popularized the idea that Christ was born on December 25 in his Chronographiai, a reference book for Christians written in AD 221. This date is nine months after the traditional date of the Incarnation (March 25), now celebrated as the Feast of the Annunciation. March 25 was considered to be the date of the vernal equinox and therefore the creation of Adam; early Christians believed this was also the date Christ was crucified. The Christian idea that Christ was conceived on the same date that he died on the cross is consistent with a Jewish belief that a prophet lived an integral number of years.Thus, the date as a birthdate for Christ is traditional, and is not considered to be his actual date of birth. The mythological aspects of the birth narrative of Christ in the gospels have been interpreted by those who ascribe to the Jesus myth hypothesis such that the figure of Christ is seen as an ahistorical construct of various forms of ancient mythology, and that there was no historical Christ, and thus no birth.

The identification of the birth date of Christ did not at first inspire feasting or celebration. Tertullian does not mention it as a major feast day in the Church of Roman Africa. In 245, the theologian Origen denounced the idea of celebrating Christ's birthday "as if he were a king pharaoh." He contended that only sinners, not saints, celebrated their birthdays.

The earliest reference to the celebration of Christmas is in the Calendar of Filocalus, an illuminated manuscript compiled in Rome in 354. In the east, meanwhile, Christians celebrated the birth of Christ as part of Epiphany (January 6), although this festival focused on the baptism of Jesus.

Christmas was promoted in the east as part of the revival of Catholicism following the death of the pro-Arian Emperor Valens at the Battle of Adrianople in 378. The feast was introduced to Constantinople in 379, to Antioch in about 380, and to Alexandria in about 430. Christmas was especially controversial in 4th century Constantinople, being the "fortress of Arianism," as Edward Gibbon described it. The feast disappeared after Gregory of Nazianzus resigned as bishop in 381, although it was reintroduced by John Chrysostom in about 400.

The Twelve Days of Christmas are the twelve days from Christmas Day to the Feast of Epiphany on January 6 that encompass the major feasts surrounding the birth of Christ: a week after Christmas Day on January 1 is the Feast of the Naming and Circumcision of Christ (Jesus was a Jew). The naming of Christ is the formal end of the Christmas story in Luke. The Feast of the Epiphany marks the visit of the Magi (wise men) and is the formal end of the Christmas story in Matthew.

Middle Ages
 
Adoration of the Magi by Don Lorenzo Monaco (1422).In the Early Middle Ages, Christmas Day was overshadowed by Epiphany, which in the west focused on the visit of the magi. But the Medieval calendar was dominated by Christmas-related holidays. The forty days before Christmas became the "forty days of St. Martin" (which began on November 11, the feast of St. Martin of Tours), now known as Advent. In Italy, former Saturnalian traditions were attached to Advent.[10] Around the 12th century, these traditions transferred again to the Twelve Days of Christmas (December 26 - January 6); a time that appears in the liturgical calendars as Christmastide or Twelve Holy Days.[10]

The prominence of Christmas Day increased gradually after Charlemagne was crowned on Christmas Day in 800. King William I of England was crowned on Christmas Day 1066. Christmas during the Middle Ages remained a public festival, incorporating ivy, holly, and other evergreens, as well as gift-giving. Christmas gift-giving during the Middle Ages was practiced more often between people with legal relationships (i.e. tenant and landlord) than between close friends and relatives.

By the High Middle Ages, the holiday had become so prominent that chroniclers routinely noted where various magnates celebrated Christmas. King Richard II of England hosted a Christmas feast in 1377 at which twenty-eight oxen and three hundred sheep were eaten.The Yule boar was a common feature of medieval Christmas feasts. Caroling also became popular, and was originally a group of dancers who sang. The group was composed of a lead singer and a ring of dancers that provided the chorus. Various writers of the time condemned caroling as lewd, indicating that the unruly traditions of Saturnalia and Yule may have continued in this form. "Misrule" — drunkenness, promiscuity, gambling — was also an important aspect of the festival. In England, gifts were exchanged on New Year's Day, and there was special Christmas ale.

[edit] From the Reformation to the 1800s
During the Reformation, some Protestants condemned Christmas celebration as "trappings of popery" and the "rags of the Beast". The Roman Catholic Church responded by promoting the festival in an even more religiously oriented form. Following the Parliamentary victory over King Charles I during the English Civil War, England's Puritan rulers banned Christmas, in 1647. Pro-Christmas rioting broke out in several cities, and for several weeks Canterbury was controlled by the rioters, who decorated doorways with holly and shouted royalist slogans. The Restoration of 1660 ended the ban, but many of the Nonconformist clergy still disapproved of Christmas celebrations, using Puritan arguments.

In Colonial America, the Puritans of New England disapproved of Christmas; its celebration was outlawed in Boston from 1659 to 1681. At the same time, Christian residents of Virginia and New York observed the holiday freely. Christmas fell out of favor in the United States after the American Revolution, when it was considered an English custom.

By the 1820s, sectarian tension in England had eased and British writers began to worry that Christmas was dying out. They imagined Tudor Christmas as a time of heartfelt celebration, and efforts were made to revive the holiday. Charles Dickens' book A Christmas Carol, published in 1843, played a major role in reinventing Christmas as a holiday emphasizing family, goodwill, and compassion over communal celebration and hedonistic excess.

Interest in Christmas in America was revived in the 1820s by several short stories by Washington Irving appearing in his The Sketch Book of Geoffrey Crayon and "Old Christmas", and by Clement Clarke Moore's 1822 poem A Visit From St. Nicholas (popularly known by its first line: Twas the Night Before Christmas). Irving's stories depicted harmonious warm-hearted holiday traditions he claimed to have observed in England. Although some argue that Irving invented the traditions he describes, they were widely imitated by his American readers. The poem A Visit from Saint Nicholas popularized the tradition of exchanging gifts and seasonal Christmas shopping began to assume economic importance. In her 1850 book "The First Christmas in New England", Harriet Beecher Stowe wrote a character who complained that the true meaning of Christmas was being lost in a shopping spree.

Christmas was declared a United States Federal holiday in 1870, signed into law by President Ulysses S. Grant. Starting in the late 1800s, the economic importance of Christmas led to concerns over what has

Christmas as a celebration of the nativity
 
Adorazione del Bambino (Adoration of the Child) (1439-43), a mural by Florentine painter Fra Angelico.The Nativity of Jesus refers to the Christian belief that the messiah was born to the Virgin Mary. The story of Christmas is based on the biblical accounts given in the Gospel of Matthew, namely Matthew 1:18-Matthew 2:12 and the Gospel of Luke, specifically Luke 1:26-Luke 2:40. According to these accounts, Jesus was born to Mary, assisted by her husband Joseph, in the city of Bethlehem. According to popular tradition, the birth took place in a "stable", surrounded by farm animals, though neither the “stable” nor the animals are mentioned in the Biblical accounts. However, a "manger" is mentioned in Luke 2:7 where it states "She wrapped him in cloths and placed him in a manger, because there was no room for them in the inn." Shepherds from the fields surrounding Bethlehem were told of the birth by an angel, and were the first to see the child.[18] Christians believe that the birth of Jesus fulfilled many prophecies made hundreds of years before his birth.

The word "Christmas" originated as a contraction of "Christ's mass." It is derived from the Middle English Christemasse and Old English Cristes mæsse, a phrase first recorded in 1038. After the conversion of Anglo-Saxon Britain in the very early 7th century, Christmas was referred to as geol,the name of the pre-Christian solstice festival from which the current English word 'Yule' is derived.[19] In early Greek versions of the New Testament, the letter Χ (chi), is the first letter of Christ (Χριστός). Since the mid-sixteenth century Χ, or the similar Roman letter X, was used as an abbreviation for Christ. Hence, "Xmas" is often used as an abbreviation for Christmas.

Remembering or re-creating the Nativity is a central way that Christians celebrate Christmas. The Eastern Orthodox Church practices the Nativity Fast in anticipation of the birth of Jesus, while much of the Western Church celebrates Advent. In some Christian churches, children perform plays re-telling the events of the Nativity, or sing carols that reference the event. Some Christians also display a small re-creation of the Nativity, known as a Nativity scene, in their homes, using figurines to portray the key characters of the event. Live Nativity scenes are also performed, using actors and live animals to portray the event with more realism.

Nativity scenes traditionally include the Three Wise Men, Balthazar, Melchior, and Caspar, although their names and number are not referred to in the Biblical narrative, who are said to have followed a star, known as the Star of Bethlehem, found Jesus, and presented gifts of gold, frankincense, and myrrh.

In the U.S., Christmas decorations at public buildings once commonly included Nativity scenes. This practice has led to many lawsuits, as groups such as the American Civil Liberties Union believe it amounts to the government endorsing a religion. In 1984, the U.S. Supreme Court ruled that a city-owned Christmas display, even one with a Nativity scene, does not violate the First Amendment.

Christmas as a secular holiday
Throughout the 20th century, the United States experienced what became known as the Christmas controversies over the nature of the day, and its dual status as a religious feast day and a secular holiday of the same name. The importance of the economic impact of the secular Christmas holiday was reinforced in the 1930s when President Franklin D. Roosevelt proposed moving the Thanksgiving holiday date to extend the Christmas shopping season and boost the economy during the Great Depression.[24] Religious leaders protested this move, with a New York Times roundup of Christmas sermons showing the most common theme as the dangers of an increasingly commercial Christmas.

"Now it is Christmas again" (1907) by Carl Larsson.Some considered the U.S. government's recognition of Christmas as a federal holiday to be a violation of the separation of church and state. This was brought to trial several times, recently including in Lynch v. Donnelly (1984) and Ganulin v. United States (1999).]

On December 6, 1999, the verdict for Ganulin v. United States (1999) declared that "the establishment of Christmas Day as a legal public holiday does not violate the Establishment Clause because it has a valid secular purpose." This decision was upheld by the U.S. Supreme Court on December 19, 2000. At the same time, many devout Christians objected to what they saw as the vulgarization and cooption of one of their sacred observances by secular commercial society and calls to return to "the true meaning of Christmas" are common.

Debates about Christmas in America continued into the 21st century. In 2005, some Christians, along with American political commentators such as Bill O'Reilly, protested what they perceived to be the secularization of Christmas. They felt that the holiday was threatened by a general secular trend, or by persons and organizations with an anti-Christian agenda. The perceived trend was also blamed on political correctness.

Santa Claus and other bringers of gifts

In Western culture, where the holiday is characterized by the exchange of gifts among friends and family members, some of the gifts are attributed to a character called Santa Claus (also known as Father Christmas, Saint Nicholas or St. Nikolaus, Sinterklaas, Kris Kringle, Joulupukki, Weihnachtsmann, Saint Basil and Father Frost).

The popular image of Santa Claus was created by the German-American cartoonist Thomas Nast (1840-1902), who drew a new image annually, beginning in 1863. By the 1880s, Nast's Santa had evolved into the form we now recognize. The image was standardized by advertisers in the 1920s.

Father Christmas, who predates the Santa Claus character, was first recorded in the 15th century, but was associated with holiday merrymaking and drunkenness.In Victorian Britain, his image was remade to match that of Santa. The French Père Noël evolved along similar lines, eventually adopting the Santa image. In Italy, Babbo Natale acts as Santa Claus, while La Befana is the bringer of gifts and arrives on the eve of the Epiphany. It is said that La Befana set out to bring the baby Jesus gifts, but got lost along the way. Now, she brings gifts to all children. In some cultures Santa Claus is accompanied by Knecht Ruprecht, or Black Peter. In other versions, elves make the toys. His wife is referred to as Mrs. Claus.

The current tradition in several Latin American countries (such as Venezuela) holds that while Santa makes the toys, he then gives them to the Baby Jesus, who is the one who actually delivers them to the children's homes. This story is meant to be a reconciliation between traditional religious beliefs and modern day globalization, most notably the iconography of Santa Claus imported from the United States.

Made for Charles Dickens's novel A Christmas Carol (1843).In Southern Germany, Switzerland, Austria, Alto Adige/Südtirol (Italy) and Liechtenstein the Christkind brings the presents. The German St. Nikolaus is not identical with the Weihnachtsman (who is the German version of Santa Claus). St. Nikolaus wears a bishop's dress and still brings small gifts (usually candies, nuts and fruits) on December 6 and is accompanied by Knecht Ruprecht. Although many parents around the world routinely teach their children about Santa Claus and other gift bringers, some have come to reject this practice, considering it deceptive.

Christmas tree and other decorations
Main article: Christmas tree
The Christmas tree is often explained as a Christianization of pagan tradition and ritual surrounding the Winter Solstice, which included the use of evergreen boughs,[31] and an adaptation of pagan tree worship. The English language phrase "Christmas tree" is first recorded in 1835[29] and represents an importation from the German language. The modern Christmas tree tradition is believed to have begun in Germany in the 18th century though many argue that Martin Luther began the tradition in the 16th century.[33] From Germany the custom was introduced to England, first via Queen Charlotte, wife of George III, and then more successfully by Prince Albert during the reign of Queen Victoria. Around the same time, German immigrants introduced the custom into the United States. Christmas trees may be decorated with lights and ornaments.

The Slovenian version of Santa, Ded Moroz or Father Frost.Since the 19th century, the poinsettia has been associated with Christmas. Other popular holiday plants include holly, mistletoe, red amaryllis, and Christmas cactus. Along with a Christmas tree, the interior of a home may be decorated with these plants, along with garlands and evergreen foliage.

In Australia, North and South America, and to a lesser extent Europe, it is traditional to decorate the outside of houses with lights and sometimes with illuminated sleighs, snowmen, and other Christmas figures. Municipalities often sponsor decorations as well. Christmas banners may be hung from street lights and Christmas trees placed in the town square.

In the Western world, rolls of brightly-colored paper with secular or religious Christmas motifs are manufactured for the purpose of wrapping gifts. The display of Christmas villages has also become a tradition in many homes during this season. Other traditional decorations include bells, candles, candy canes, stockings, wreaths, and angels.

Economics of Christmas

Christmas display in a Brazilian shopping mallChristmas is typically the largest annual economic stimulus for many nations. Sales increase dramatically in almost all retail areas and shops introduce new products as people purchase gifts, decorations, and supplies. In the U.S., the "Christmas shopping season" generally begins on Black Friday, the day after Thanksgiving, though many American stores begin selling Christmas items in October and early November.

In most areas, Christmas Day is the least active day of the year for business and commerce; almost all retail, commercial and institutional businesses are closed, and almost all industries cease activity (more than any other day of the year). In England and Wales, the Christmas Day (Trading) Act 2004 prevents all large shops from trading on Christmas Day. Scotland is currently planning similar legislation. Film studios release many high-budget movies in the holiday season, including Christmas films, fantasy movies or high-tone dramas with high production values.

An economists analysis calculates that Christmas is a deadweight loss under orthodox microeconomic theory, due to the surge in gift-giving. This loss is calculated as the difference between what the gift giver spent on the item and what the gift receiver would have paid for the item. It is estimated that in 2001 Christmas resulted in a $4 billion deadweight loss in the U.S. alone. Because of complicating factors, this analysis is sometimes used to discuss possible flaws in current microeconomic theory. Other deadweight losses include the effects of Christmas on the environment and the fact that material gifts are often perceived as white elephants, imposing cost for upkeep and storage and contributing to clutter.
