The day and year of the birth of Jesus Christ.

The birth of Jesus Christ is traditionally celebrated on December 25th, around the year 4 BC to 6 BC.

The exact day and year of Jesus Christ's birth are not known with certainty, but there is general consensus among historians that he was born between 6 and 4 BC. The Bible does not mention the specific date of Jesus' birth, but it does provide some clues. For example, the Gospel of Luke states that Jesus was born during the reign of Caesar Augustus (Luke 2:1), who ruled from 27 BC to 14 AD. Additionally, the Gospel of Matthew states that Jesus was born in Bethlehem of Judea (Matthew 2:1), which was part of the Roman province of Judea at the time.

Based on these clues, historians have estimated that Jesus was most likely born between 6 and 4 BC. However, there is still some debate among scholars about the exact year of his birth.
