For centuries, December 25 has been celebrated as the birthday of Jesus Christ, central to Christian tradition and festive joy worldwide. However, scholars and historians agree that the actual date of Jesus’ birth likely wasn’t in December. Instead, modern studies suggest he may have been born in spring, with March or September being the most probable months.
Professor Lawrence Mykytiuk of Purdue University remarked, “It remains a humbling fact that despite various claims, no one in modern times is really certain of the exact year of Jesus’ birth”. So, why has this narrative persisted for so long?
Historical Clues
One of the strongest pieces of evidence for determining Jesus’ birth year comes from the historical records surrounding King Herod the Great. According to the Bible, Herod, fearing the birth of a “King of the Jews,” ordered the massacre of male infants under two years old. This event suggests that Jesus was born at least two years before Herod’s death.
The Jewish historian Flavius Josephus provides details about Herod’s death, which occurred shortly after a lunar eclipse. Based on astronomical data, scholars identify four possible dates for this eclipse: September 15, 5 BC; March 13, 4 BC; January 10, 1 BC; or December 29, 1 BC. The timing of the Jewish Passover shortly afterward rules out the latter two dates, making 4–6 BC a likely range for Jesus’ birth year.
The Weather and Shepherds’ Clues
Another piece of the puzzle comes from the biblical description of shepherds watching over their flocks at night. Professor Mykytiuk noted, “During winter, shepherds kept sheep in the fold to protect themselves and their sheep from severe weather”. This aligns with spring, a time when shepherds traditionally grazed their flocks outdoors.
Adding weight to this theory is the abundance of fresh grass in March, supporting the possibility that Jesus was born in the spring.
The Star of Bethlehem
The “Star of Bethlehem,” which guided the Magi, may also provide clues about Jesus’ birth. Some researchers believe the star was a comet recorded by Chinese astronomers in 5 BC, which remained visible for 70 days. Others propose it was a rare triple conjunction of Jupiter and Saturn in 6 BC, symbolizing royalty and divinity to ancient astronomers.
Physicist Colin Humphreys suggests, “According to the Chinese records, the star appeared in the spring of 5 BC, consistent with the Gospel of Luke saying that there were shepherds out in the fields”.

Why December 25?
The association of December 25 with Jesus’ birth likely stems from theological and cultural developments. Early Christians calculated Jesus’ conception to align with Passover, believing he was conceived and crucified on the same date—March 25. Adding nine months brings his birth to December 25.
Some historians have speculated that Christmas was moved to coincide with pagan solstice festivals, such as Saturnalia or Sol Invictus, to attract converts. However, Yale scholar Andrew McGowan refutes this, stating, “The first mention of a date for Christmas came during a period when Christians were not borrowing heavily from pagan traditions”.
The Role of Dionysius Exiguus
The calculation of “Anno Domini” (Year of Our Lord) is another factor in the confusion surrounding Jesus’ birth year. Dionysius Exiguus, a 6th-century monk, attempted to establish a calendar beginning with Jesus’ birth but miscalculated the dates of King Herod and other historical markers. His error places Jesus’ birth several years earlier than 1 AD.
Spring or September?
While spring is a popular theory, some scholars argue for a September birth based on the timing of John the Baptist’s birth. Luke’s Gospel indicates that John’s mother, Elizabeth, conceived six months before Mary. By tracing the priestly rotation of Zechariah, John’s father, scholars estimate Jesus’ birth occurred in the fall.
Ian Paul, a theologian, stated, “A fall date for Christmas makes sense when you consider that the shepherds were in the fields tending their flocks, a sign of mild weather”.
Does the Date Matter?
Despite the historical intrigue, many theologians suggest that pinpointing the exact date of Jesus’ birth misses the spiritual essence of Christmas. “We’re celebrating an event, not a day,” said Professor Thomas Wayment of Brigham Young University.
Whether in December, March, or September, the story of Jesus’ birth continues to inspire faith and reflection across the globe.
Conclusion
The quest to determine Jesus’ actual birth date reveals fascinating intersections of history, astronomy, and theology. While evidence points toward a spring or fall birth in 4–6 BC, the exact details remain elusive. Yet, as scholars like Wayment emphasize, the significance of Christmas transcends its calendar date, reminding believers of its profound message of hope and redemption.
