Christmas is an annual celebration taking place on December 25th, commemorating the birth of Jesus Christ. The holiday is celebrated by people of different religions and cultures all around the world.
Despite Christmas being associated with the birth of Jesus Christ, there is no biblical passage or other evidence establishing Jesus's date of birth. In early-to-mid 4th century, The Western Christian Church set the date of Christmas to December 25, and was later also adopted in the East. While there is no established date for the birth of Jesus, the following passage from Luke 2:8-12 seem to suggest that he was born during the lambing season:
- "And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. But the angel said to them, “Do not be afraid. I bring you good news that will cause great joy for all the people. Today in the town of David a Savior has been born to you; he is the Messiah, the Lord. This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger.”"
Natalis Invicti ("birthday of the unconquered one") was a festival celebrating the rebirth of the sun, Sol Invictus ("Invincible Sun"), the official sun god of the Roman Empire. Scholars argue that the festival was placed on the date of the winter solstice as the sun would seemingly reverse its retreat and thereby prove itself unconquered. Early Christian writers connected the rebirth of the sun with the birth of Jesus Christ, and the festival is believed to be responsible for the date of Christmas.
