Christmas (pronounced /ˈkrɪsməs/), also referred to as Christmas Day, is an annual holiday celebrated on December 25 that commemorates the birth of Jesus of Nazareth. The day marks the beginning of the larger season of Christmastide, which lasts twelve days. The nativity of Jesus, which is the basis for the anno Domini system of dating, is thought to have occurred between 7 and 2 BC.December 25 is not known to be Jesus' actual date of birth, and the date may have been chosen to correspond with either a Roman festival or the winter solstice.

Modern customs of the holiday include gift-giving, Church celebrations, and the display of various decorations—including the Christmas tree, lights, mistletoe, nativity scenes, and holly. Santa Claus (also referred to as Father Christmas, although the two figures have different origins) is a popular mythological figure often associated with bringing gifts at Christmas for children. Santa is generally believed to be the result of a syncretization between Saint Nicholas and elements from pagan Nordic and Christian mythology, and his modern appearance is believed to have originated in 19th century media.

Christmas is celebrated throughout the Christian population, but is also celebrated by many non-Christians as a secular, cultural festival. Because gift-giving and several other aspects of the holiday involve heightened economic activity among both Christians and non-Christians, Christmas has become a major event for many retailers.


Etymology
Adoration of the Magi by Bartolomé Esteban Murillo

The word Christmas originated as a compound meaning "Christ's Mass". It is derived from the Middle English Christemasse and Old English Cristes mæsse, a phrase first recorded in 1038. "Cristes" is from Greek Christos and "mæsse" is from Latin missa. In Greek, the letter Χ (chi), is the first letter of Christ, and it, or the similar Roman letter X, has been used as an abbreviation for Christ since the mid-16th century. Hence, Xmas is often used as an abbreviation for Christmas.

History

For many centuries, Christian writers accepted that Christmas was the actual date on which Jesus was born. However, in the early eighteenth century, scholars began proposing alternative explanations. Isaac Newton argued that the date of Christmas was selected to correspond with the winter solstice, which in ancient times was marked on December 25. In 1743, German Protestant Paul Ernst Jablonski argued Christmas was placed on December 25 to correspond with the Roman solar holiday Dies Natalis Solis Invicti and was therefore a "paganization" that debased the true church. In 1889, Louis Duchesne suggested that the date of Christmas was calculated as nine months after the Annunciation (March 25), the traditional date of the Incarnation.

Dies Natalis Solis Invicti
Main article: Sol Invictus

Dies Natalis Solis Invicti means "the birthday of the unconquered Sun." The use of the title Sol Invictus allowed several solar deities to be worshipped collectively, including Elah-Gabal, a Syrian sun god; Sol, the god of Emperor Aurelian; and Mithras, a soldiers' god of Persian origin. Emperor Elagabalus (218–222) introduced the festival, and it reached the height of its popularity under Aurelian, who promoted it as an empire-wide holiday. This day had held no significance in the Roman festive calendar until it was introduced in the third century.

The festival was placed on the date of the solstice because this was on this day that the Sun reversed its southward retreat and proved itself to be "unconquered." Several early Christian writers connected the rebirth of the sun to the birth of Jesus. "O, how wonderfully acted Providence that on that day on which that Sun was born...Christ should be born", Cyprian wrote. John Chrysostom also commented on the connection: "They call it the 'Birthday of the Unconquered'. Who indeed is so unconquered as Our Lord . . .?"

A winter festival was the most popular festival of the year in many cultures. Reasons included the fact that less agricultural work needs to be done during the winter, as well as an expectation of better weather as spring approached. Modern Christmas customs include: gift-giving and merrymaking from Roman Saturnalia; greenery, lights, and charity from the Roman New Year; and Yule logs and various foods from Germanic feasts. Pagan Scandinavia celebrated a winter festival called Yule, held in the late December to early January period. As Northern Europe was the last part to Christianize, its pagan traditions had a major influence on Christmas. Scandinavians still call Christmas Jul. In English, the word Yule is synonymous with Christmas, a usage first recorded in 900.
