Let's Search for the Answer!

When was Jesus born? Did God leave us clueless to the timing of one of the greatest events in world history – the coming of the Light of the World? Can we determine from the pages of our Bible the season and approximate date that Jesus was born?
The apostle Paul wrote that all scripture is given by God, and that it all has a purpose1. God didn’t waste words; everything He has written is for our benefit. But some of the things He wants us to see are not clearly spelled out – we have to do some searching, for “It is the glory of God to conceal a matter; to search out a matter is the glory of kings.” 2 So let’s begin our search for the season and possible day when Yeshua was born . . .

The Birth of John the Baptist

But where do we start? Let’s start with something God made very obvious, but something we’ve probably passed over a number of times in our reading of the story of Jesus’ birth, and that's the fact that John the Baptist was born six months before Jesus. Luke’s narrative (Luke 1) tells us that when the angel Gabriel spoke to Mary about the fact that she was going to be the mother of Israel’s Messiah, her cousin Elizabeth was already six months pregnant with her son John 3. Notice that the angel told Mary that Elizabeth had 'also' conceived, implying that Mary was already with child.4
So now, all we have to do is determine when John was born. Unfortunately, the Bible doesn’t just come out and tell us when he was born, but with a little searching, we can come up with a good approximation to when he was conceived, and then, of course, we’ll know when he was born. Let’s go back to Luke’s narrative. In chapter 1, vs. 5, he introduces Zacharias, John’s father. In this and the next few verses, Luke gives us some very important details:

  • Zacharias was a priest in the course of Abia - which is a very important fact. (vs. 5)
  • Zacharias was executing his responsibilities as priest according to the order of his course. (vs. 8)
  • Zacharias was informed, while performing his duties, that he was going to have a son (vs. 13-22)
  • Zacharias remained in Jerusalem until the days of his service were complete, then he went home to his wife (vs. 23)

What does the ‘course of Abia’ have to do with John’s birth? Let’s search and see, but first, let’s learn a little bit about the Biblical calendar so we can see how it relates to our 'gregorian' calendar.

The Biblical Calendar

The Biblical calendar is lunar with the months beginning when the crescent of the new moon becomes visible and lasting about 29-30 days. The first month is in the spring and is called “Nisan”, the second is called “Iyar”, the third “Sivan”, and so on5. The Biblical festivals of Leviticus 23 are all based on the Biblical calendar.

The Divisions of the Priests

When David was King of Israel, there were a large number of priests – too many to serve on a daily basis. So David, by God’s direction, divided the priests into 24 “courses”, with each course serving for one week at a time and all of them serving during the Biblical festivals. The course of Abia was the eighth course.6
According to historical and biblical sources, the first course began its service on the first Sabbath day (Saturday) of the Biblical year.7 Going back to Leviticus 23 we find that there are festivals that take place in the first and third month of each year, Passover and the Feast of Weeks, therefore, the course of Abia’s time of service was always pushed to the tenth or eleventh week (depending on if Passover spanned two weeks or not), and thus fell in the later part of the month of Sivan.
Thus - as the chart below shows - Zacharias was serving from about the fourteenth to the twenty first day of Sivan. When his course was finished, he returned home, which we assume is about a two to three day walk. And assuming he didn’t waste any time in trying to bring the angel’s prophecy to fruition, John was conceived about the twenty-fourth day of Sivan, probably a Tuesday or Wednesday.
A normal pregnancy is about 40 weeks. If you take a Jewish calendar (which closely follows the Biblical calendar) and count 40 weeks, you come to the middle of the second week of the first month (Nisan).8 So now we see that John was born very close to, if not on, the tenth of Nisan (the day the lambs were chosen for Passover).
Now that we have the date of John’s birth, all we have to do to determine when Jesus was born is to go back to our first fact (John is six months older than Jesus) and go on down the calendar six months. Again, take a Jewish calendar and count six months from John’s birth and you come to the middle of the second week of the month of Tishri.9 Comparing this date to our present Gregorian calendar, we find that Jesus was born during the fall, from about the third week of September to the second week of October.

It All Fits Perfectly!

The Old Testament book of Leviticus chapter 23 contains God's instructions to Israel in regards to His seasonal festivals. Contrary to common Christian belief, these festivals are not ‘Jewish’10 but are given by God to all His people for a specific purpose - to teach about His plan of salvation through Jesus our Messiah.

Most of us see the connection between Jesus, the Lamb of God, and the Passover - which is the first biblical festival in the yearly cycle. We also know that the Apostles were gathered in the Temple on the Day of Pentecost11 - the second seasonal festival - when they received the gift of the Holy Spirit.  Would it not then stand to reason that the fall festivals – The Feast of Trumpets, the Day of Atonement, the Feast of Tabernacles, and the Eighth Day Festival – have significance as well?  Could it not be that the fall festivals show us when the Messiah did appear ... and then will 're-appear'?  Let’s look at the connections:

The first festival in the fall festival seasoin occurs on the first day of Tishri it is called the Feast of Trumpets12, or literally, the Day of Shouting13. It is customary to announce this day with the blowing of a ram’s horn – a Shofar. Paul spoke of this day in regards to the return of The Messiah and the resurrection of the dead14. In Jewish understanding, this day is also considered the day when The Bridegroom comes to fetch His bride.

Tishri 10 - the likely date of Jesus' birth - is Yom Kippur, the Day of Atonement15. The Jubilee year always begins on this day, and according to tradition, The Messiah will return to the earth on Yom Kippur to gather the remnant of His people for the 1000 year Messianic kingdom – a great time of peace on earth. Five days later, Tishri 15, begins the Feast of Tabernacles16 – referred to in many Jewish writings as the “Season of Our Joy”. For 1000 years Jesus the Messiah will “tabernacle” with His people, restoring joy and peace to mankind. It will truly begin the 'restoration of all things'.

It is interesting to note that if you count back 40 weeks (the normal gestation period for a human) from Yom Kippur, you come to within a couple of days either side of Kislev 25 which is the first day of Hannukah - the Festival of Lights.

As we read the narrative surrounding the birth of Jesus18, we see connections to these fall festival themes. With the mention of peace, joy, and good will, could it be that the angels were hinting to us that the coming of Jesus is the fulfillment of these special biblical festivals? If Jesus is the fulfillment of the spring festivals, it would certainly stand to reason that He would also be the fulfillment of the fall festivals as well.

It all fits perfectly!
