Christmas

Christmas or Christmas Day is an annual holiday commemorating the birth of Jesus Christ,[5] [6] celebrated generally on December 25[2] [3] [4] by billions of people around the world. A feast central to the Christian liturgical year, it closes the Advent season and initiates the season ofChristmastide, which lasts twelve days.[7] In much of the world's nations Christmas is a civil holiday,[8] [9] [10] is celebrated by an increasing number of non-Christians,[1] [11] [12] and is an integral part of the Christmas and holiday season.

The precise day of Jesus’ birth, which historians place between 7 and 2 BC, is unknown. In the early-to-mid 4th century, the Western Christian Church first placed Christmas on December 25, a date later adopted also in the East.[13] [14] Theories advanced to explain that choice include that it falls exactly nine months after the Christian celebration of the conception of Jesus,<sup class="reference" id="cite_ref-bib-arch.org_14-0" style="line-height: 1em; font-weight: normal; font-style: normal; ">[15] or that it was selected to coincide with either the date of the Roman winter solstice<sup class="reference" id="cite_ref-Newton_15-0" style="line-height: 1em; font-weight: normal; font-style: normal; ">[16] or of some ancient winter festival.<sup class="reference" id="cite_ref-bib-arch.org_14-1" style="line-height: 1em; font-weight: normal; font-style: normal; ">[15] <sup class="reference" id="cite_ref-SolInvictus_16-0" style="line-height: 1em; font-weight: normal; font-style: normal; ">[17]

<p style="margin-top: 0.4em; margin-right: 0px; margin-bottom: 0.5em; margin-left: 0px; line-height: 1.5em;">The original date of the celebration in Eastern Christianity was January 6 (see Epiphany), and that is still the date of the celebration in Armenia, where it is a public holiday, and for the Armenian Apostolic Church. As of 2011, there is a difference of 13 days between the Julian calendar and the more generally used Gregorian calendar. Those who use the Julian calendar or its equivalents thus celebrate December 25 and January 6 on what for the majority of people is January 7 and January 19. For this reason, Ethiopia celebrates Christmas, both as a Christian feast and as a public holiday on what in the Gregorian Calendar is January 7.<sup class="reference" id="cite_ref-17" style="line-height: 1em; font-weight: normal; font-style: normal; ">[18]

<p style="margin-top: 0.4em; margin-right: 0px; margin-bottom: 0.5em; margin-left: 0px; line-height: 1.5em;">Many of the popular celebratory customs associated in various countries with Christmas have pre-Christian or secular themes and origins. Popular modern customs of the holiday include gift-giving, music, an exchange of Christmas cards, church celebrations, a special meal, and the display of various decorations; including Christmas trees, lights, garlands, mistletoe, nativity scenes, and holly. In addition, several figures, known as Saint Nicholas, Father Christmas, and Santa Claus, among other names, are associated with bringing gifts to children during the Christmas season.<sup class="reference" id="cite_ref-18" style="line-height: 1em; font-weight: normal; font-style: normal; ">[19] Because gift-giving and many other aspects of the Christmas festival involve heightened economic activity among both Christians and non-Christians, the holiday has become a significant event and a key sales period for retailers and businesses. The economic impact of Christmas is a factor that has grown steadily over the past few centuries in many regions of the world.
