On Which Day of the Year Was Jesus Really Born?
Not on December 25, because shepherds would not be tending sheep in the field that time of the year.
But the Bible does provide us with some clues. The priest Zacharias, the father of John the Baptist, was of the “course of Abia” (Luke 1:5). Of a total of 24 courses, according to I Chronicles 24:10, the course of Abia was the eighth to minister in the temple.
While Zacharias was engaged in his priestly duties, an angel told him that his aged wife, Elisabeth, would bear a son who was to be called John (Luke 1:13).
Luke 1:36 then reveals that when the virgin Mary was told by an angel that she would soon be with child, who would be called the Son of the Most High, her cousin Elisabeth was in the sixth month of her pregnancy. The middle of Elisabeth’s sixth month would have been five-and-a-half months after July 8, which means that Mary began to carry Christ around the end of December.
As the typical normal pregnancy lasts a little more than nine months, Jesus would have been born during or near the first week of October.
