http://biblelight.net/sukkoth.htm On What Day Was Jesus Born? While much of the world celebrates the birth of Jesus Christ on the 25th of December, can the actual day of Jesus' birth be determined from scripture? This question will be explored in some detail, and will yield a result that is quite intriguing. The first passage we will consider begins with the father of John the Baptist, Zacharias:
Luke 1:5 There was in the days of Herod, the king of Judaea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth.
Luke 1:8 And it came to pass, that while he executed the priest's office before God in the order of his course, ...
Luke 1:23 And it came to pass, that, as soon as the days of his ministration were accomplished, he departed to his own house.
Luke 1:24 And after those days his wife Elisabeth conceived, ...
The clue given to us here is that Zacharias was of the "course" of Abia.
The Conception of Jesus Christ.
Now the reason that the information about John is important, is because according to Luke, Jesus was conceived by the Holy Spirit in the sixth month of Elisabeth's pregnancy:
Luke 1:24 And after those days his wife Elisabeth conceived, and hid herself five months, saying,
Luke 1:25 Thus hath the Lord dealt with me in the days wherein he looked on me, to take away my reproach among men.
Luke 1:26 And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,
Luke 1:27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary.
Note that verse 26 above refers to the sixth month of Elisabeth's pregnancy, not Elul, the sixth month of the Hebrew calendar, and this is made plain by the context of verse 24 and again in verse 36:
Luke 1:36 And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren.
Mary stayed with Elizabeth for the last 3 months of her pregnancy, until the time that John was born.
Luke 1:56 And Mary abode with her about three months, and returned to her own house.
Luke 1:57 Now Elisabeth's full time came that she should be delivered; and she brought forth a son.
Now working from the information about John's conception late in the third month, Sivan, and advancing six months, we arrive late in the 9th month of Kislev (Nov-Dec) for the time frame for the conception of Jesus. It is notable here that the first day of the Jewish festival of Hanukkah, the Festival of Lights, is celebrated on the 25th day of Kislev, and Jesus is called the light of the world (John 8:12, 9:5, 12:46). This does not appear to be a mere coincidence. In the book of John, Hanukkah is called the feast of dedication (John 10:22). Hanukkah is an eight day festival of rejoicing, celebrating deliverance from enemies by the relighting of the menorah in the rededicated Temple, which according to the story, stayed lit miraculously for eight days on only one day's supply of oil.
The Birth of Jesus Christ.
Since Jesus was conceived six months after John the Baptist, and we have established a likely date for John's birth, we need only move six months farther down the Jewish calendar to arrive at a likely date for the birth of Jesus. From the 15th day of the 1st month, Nisan, we go to the 15th day of the 7th month, Tishri. And what do we find on that date? It is the festival of Tabernacles! The 15th day of Tishri begins the third and last festival of the year to which all the men of Israel were to gather in Jerusalem for Temple services. (Lev 23:34)
So, if you have followed the above reasoning, based on the scriptural evidence, a case can apparently be made that Jesus Christ was born on the 15th day of the month of Tishri, on the first day of the Feast of Tabernacles, which corresponds to the September - October timeframe of our present calendar!
