Christmas Girls

• Date of celebration
For centuries, Christian writers accepted that Christmas was the actual date on which Jesus was born. John Chrysostom preached a sermon in Antioch c. 386 which established the date of Christmas as December 25 on the Julian calendar since the conception of Jesus (Luke 1:26) had been announced during the sixth month of Elisabeth's pregnancy with John the Baptist (Luke 1:10-13) as dated from the duties Zacharias performed on the Day of Atonement during the seventh month of the Hebrew calendar Ethanim or Tishri (Lev. 16:29, 1 Kings 8:2) which falls in September-October. In the early 18th century, scholars began proposing alternative explanations. Isaac Newton argued that the date of Christmas was selected to correspond with the winter solstice, which the Romans called bruma and celebrated 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 Annunciation, the traditional date of the conception of Jesus.
The December 25 date may have been selected by the church in Rome in the early 4th century. At this time, a church calendar was created and other holidays were also placed on solar dates: "It is cosmic symbolism...which inspired the Church leadership in Rome to elect the winter solstice, December 25, as the birthday of Christ, and the summer solstice as that of John the Baptist, supplemented by the equinoxes as their respective dates of conception. While they were aware that pagans called this day the 'birthday' of Sol Invictus, this did not concern them and it did not play any role in their choice of date for Christmas," according to modern scholar S.E. Hijmans.
However, today, whether or not the birth date of Jesus is on December 25 is not considered to be an important issue in mainstream Christian denominations; rather, celebrating the coming of God into the world in the form of man to atone for the sins of humanity is considered to be the primary meaning of Christmas.
