December 25 was chosen as "Christmas" to celebrate the birth of Jesus around 354 AD. Prior to that, the birth of Jesus was celebrated by early Christians as the Feast of Epiphany, which corresponded to the Jewish Festival of Lights (Hanukkah).
Epiphany was moved to December 25 because the Roman winter solstice holiday known as the Feast of the Invincible Sun was celebrated on that day. The Church decided to overtake and displace this pagan festival by moving the Epiphany celebration to December 25, and declaring that Jesus was "The Only Invincible One" and the "Sun of Justice."
My prayer this Christmas for you and your family is that you all have a wonderful, safe, and merry Christmas, always keeping in mind the true meaning of Christmas:
" For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." (John 3:16)

The Christmas Story -- Luke 2: 8-20 (NKJV)
Now there were in the same country shepherds living out in the fields, keeping watch over their flock by night. And behold, an angel of the Lord stood before them, and the glory of the Lord shone around them, and they were greatly afraid. Then the angel said to them, “Do not be afraid, for behold, I bring you good tidings of great joy which will be to all people. For there is born to you this day in the city of David a Savior, who is Christ the Lord. And this will be the sign to you: You will find a Babe wrapped in swaddling cloths, lying in a manger.”
And suddenly there was with the angel a multitude of the heavenly host praising God and saying:
“Glory to God in the highest,
And on earth peace, goodwill toward men!”
So it was, when the angels had gone away from them into heaven, that the shepherds said to one another, “Let us now go to Bethlehem and see this thing that has come to pass, which the Lord has made known to us.” And they came with haste and found Mary and Joseph, and the Babe lying in a manger. Now when they had seen Him, they made widely known the saying which was told them concerning this Child. And all those who heard it marveled at those things which were told them by the shepherds. But Mary kept all these things and pondered them in her heart. Then the shepherds returned, glorifying and praising God for all the things that they had heard and seen, as it was told them.
