Why do we celebrate on December 25 then?

The church fixed a date centuries later so believers could commemorate the birth together. The chosen day carries meaning by tradition, not by historical record of the actual birth.

Do all Christians use December 25?

No. Many Eastern Orthodox churches celebrate the nativity on January 6 or 7, reflecting older traditions and calendar differences rather than a dispute over the real date.

Is that true?

Was Jesus born on December 25?

False

False, or at least unproven. The Bible gives no birth date for Jesus, and December 25 was not celebrated as his birthday until the fourth century. Luke's shepherds keeping watch by night may even hint at a warmer season. The true date is simply unknown.

The history

No New Testament text records the day or month of Jesus' birth. The earliest firm reference to December 25 as his nativity appears in fourth century Rome, and Eastern churches long favored January 6. Scholars debate whether the date was chosen to align with existing Roman festivals or calculated from other assumptions, but no one claims it rests on historical memory of the actual day.

What Scripture says

“And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.”Luke 2:8 (KJV)

Luke notes shepherds watching their flocks by night, a detail sometimes read as pointing away from midwinter, though it settles nothing.

Sources. The Gospels of Matthew and Luke (which give no date), early Christian writings placing the feast in the fourth century, and mainstream scholarship on the origins of Christmas dating.

Where this points

The gospel never anchors its hope to a calendar square. What Scripture insists on is not the day but the fact: the Word became flesh and dwelt among us. Christmas, whenever we mark it, celebrates that God drew near to a world that could not reach him.
