All about Christmas

Pre-Christian origins of holiday
Christmas has its origins in several pagan holidays. The celebration known as Saturnalia included the making and giving of small presents (saturnalia et sigillaricia). This holiday was observed over a series of days beginning on December 17 (the birthday of Saturn) and ending on December 25 (the birthday of Sol Invictus, the "unconquered sun"). The combined festivals resulted in an extended winter holiday season. Business was postponed and even slaves feasted. There was drinking, gambling, and singing, and nudity was relatively common. It was the "best of days," according to the poet Catullus.[3]

During the time in which Christianity was spreading throughout the Roman Empire, another similar religion known as Mithraism was also gaining widespread acceptance. The followers of Mithraism worshipped Mithras, a god of Persian origin, who was identified with Sol Invictus. [citation needed] The followers of Mithraism, consequently, adopted the birthday of Sol Invictus as the birthday of Mithras. In 274 AD, due to the popularity of Mithraism, Emperor Aurelian designated December 25 as the festival of Sol Invictus.

[edit] Christian origins of holiday
Around 220 AD, the theologian Tertullian declared that Jesus died on March 25, 29, but was resurrected three days later. Although this is not a plausible date for the crucifixion, it does suggest that March 25, nine months before December 25th, had significance for the church even before it was used as a basis to calculate Christmas. Modern scholars favor a crucifixion date of April 3, 33, which was also the date of a partial lunar eclipse (These are Julian calendar dates. Subtract two days for a Gregorian date.).[4]

By 240 AD, a list of significant events was being assigned to March 25, partly because it was believed to be the date of the vernal equinox. These events include creation, The Fall of Adam and Eve, and, most relevantly, the Incarnation.[5] The view that the Incarnation occurred on the same date as crucifixion is consistent with a Jewish belief that prophets died at an "integral age," either an anniversary of their birth or of their conception.[6][7]

The idea that December 25 is Jesus' birthday was popularized by Sextus Julius Africanus in Chronographiai (221 AD), an early reference book for Christians. This identification did not at first inspire feasting or celebration. In 245 AD, the theologian Origen denounced the idea of celebrating the birthday of Jesus

Christmas 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 stores start selling Christmas items in October/November (and in the UK, even September/October).

More businesses and stores close on Christmas Day than any other day of the year. In the United Kingdom, the Christmas Day (Trading) Act 2004 prevents all large shops from trading on Christmas Day.

Most economists agree, however, that Christmas produces 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.[16][17] Because of complicating factors, this analysis is sometimes used to discuss possible flaws in current microeconomic theory.

In North America, film studios release many high-budget movies in the holiday season, including Christmas films, fantasy movies or high-tone dramas with rich production values.

In Western culture, the holiday is characterized by the exchange of gifts among friends and family members, some of the gifts being attributed to Santa Claus (also known as Father Christmas, Saint Nicholas, Kris Kringle, Saint Basil and Father Frost).

Father Christmas predates the Santa Claus character, and was first recorded in the 15th century,[18] but was associated with holiday merrymaking and drunkenness. Santa Claus is a variation of a Dutch folk tale based on the historical figure Saint Nicholas, or Sinterklaas, who gave gifts on the eve of his feast day of December 6. He became associated with Christmas in 19th century America and was renamed Santa Claus or Saint Nick. In Victorian Britain, Father Christmas's imag
