The date of birth of Jesus is not stated in the gospels or in any historical reference, but most biblical scholars assume a year of birth between 6 and 4 BC.
When was Jesus's actual birthday?
By the fourth century, however, we find references to two dates that were widely recognized — and now also celebrated — as Jesus’ birthday: December 25 in the western Roman Empire and January 6 in the East (especially in Egypt and Asia Minor).
What month of the year was Jesus born?
The Virgin Mary, pregnant with the son of God, would hence have given birth to Jesus nine months later on the winter solstice. From Rome, the Christ’s Nativity celebration spread to other Christian churches to the west and east, and soon most Christians were celebrating Christ’s birth on December 25.
