For centuries, millions of people around the world have celebrated the birth of Jesus every December 25th. Lights, trees, carols, and family gatherings have become part of a tradition that transcends cultures and generations.
But there’s a question few dare to ask: Is that date really the correct one according to the Bible?
Scripture never mentions December 25th as the day of Jesus’ birth. In fact, when the biblical account is carefully examined, a very different story emerges.
The Historical Origin of December 25th
December 25th was not a date established by Jesus, the apostles, or the early Christian church.
It was officially adopted in 336 AD, under the Roman Emperor Constantine.
In the Roman Empire, that day was celebrated as one of the most important pagan festivals: Natalis Solis Invicti, the birth of the Unconquered Sun. It was a festival dedicated to the sun god, very popular among the Romans.
When Christianity began to spread, Constantine decided to superimpose the celebration of Christ’s birth onto this pagan festival in order to facilitate the conversion of the Roman people. Thus, the date was Christianized, but it wasn’t based on a biblical event.
The climatic evidence that rules out winter
Luke 2:8 describes shepherds tending their flocks at night in open fields when Jesus was born.
This seems like a minor detail, but it’s actually key.
In the Bethlehem region, the winter months (December and January) have temperatures close to freezing and constant rain. During that period, shepherds didn’t leave their sheep outdoors; they kept them in covered pens.
The flocks only remained in the fields from spring to autumn, approximately from March to November.
That means Jesus couldn’t have been born in the middle of winter.
The Roman Census: Another Piece of the Puzzle
Luke also mentions that Joseph and Mary had to travel from Nazareth to Bethlehem for a census ordered by Caesar Augustus. That journey was over 130 kilometers (80 miles).
The Roman Empire never conducted censuses in winter. The roads became dangerous, muddy, and impassable, especially in mountainous regions. Censuses were always carried out during dry, temperate seasons.
Another clear piece of evidence that the birth did not occur in December.
The Hidden Detail in Luke That Reveals Everything
The most precise clue is in Luke chapter 1.
Zechariah, the father of John the Baptist, belonged to the priestly division of Abijah. According to 1 Chronicles 24, that division served during the eighth week of the Jewish calendar, which corresponds approximately to mid-June.
After completing his service, his wife Elizabeth became pregnant.
Nine months later, John the Baptist was born around March or April.
Six months into that pregnancy, the angel Gabriel visited Mary. This places the conception of Jesus around September.
Nine months later, Jesus would have been born between the end of September and the beginning of October.
The Connection to the Feast of Tabernacles
This period coincides with the Feast of Tabernacles (Sukkot), one of the most important celebrations in the biblical calendar, which commemorates when God dwelt among his people in the desert.
John 1:14 says that “the Word became flesh and dwelt among us.” In the original language, that word literally means “tabernacled.”
That is, Jesus would have been born precisely when Israel was celebrating God dwelling with his people.
Why was there no room at the inn?
In December, Bethlehem was a quiet town.
But during the Feast of Tabernacles, hundreds of thousands of pilgrims traveled to Jerusalem, and Bethlehem became completely full.
This explains why Joseph and Mary couldn’t find lodging.
Even the rabbis expected it this way.
Ancient rabbinic texts indicate that many Jewish sages expected the Messiah to be born during Sukkot.
Theology, prophecy, and the calendar fit together like a perfect puzzle.
So should we stop celebrating December 25th?
That’s a personal decision.
What truly matters is not the exact day, but that Jesus was indeed born, came into the world, died, and rose again.
December 25th is a human tradition, beautiful and laden with cultural significance. But the Bible points to the Messiah’s birth occurring in autumn, during the Feast of Tabernacles.
Tips and Recommendations
• Study the Bible for yourself and don’t rely solely on traditions.
Learn to separate the cultural from the biblical without losing respect for either.
• Share this information with humility, not to create division, but to encourage reflection. • Remember that faith is not based on a date, but on a person: Jesus.
• Use these truths to strengthen your spiritual relationship, not to argue.
