You might think that Jesus was born in the Year Zero–between 1 B.C. and A.D. 1.

You often hear that Jesus was born around 6-7 B.C.

The evidence from the Bible and the Church Fathers, however, support a different year.

Here’s what the evidence says . . .

 

Not in Year Zero

There is a good reason why Jesus wasn’t born in Year Zero: There wasn’t one.

The sequence of years before Christ ends at 1 B.C. and the A.D. series picks up the very next year with A.D. 1.

This is a bit surprising to us, since we’re used to working with number lines that have a zero on them, but zero wasn’t a concept on the intellectual scene when our way of reckoning years was developed.

If it helps, you can think about it this way: Suppose you have a child and you want to date events relative to that child’s birth. The first year before the child was born would be 1 B.C. (Before the Child), and the first year after his birth (that is, the year ending with his first birthday) would be the first year of the child.

If the child happens to be the Lord, that would be the first year of the Lord, which in Latin is Anno Domini, from which we get A.D.

Thus there is no Year Zero between 1 B.C. and A.D. 1.

(BTW, please note that the “A.D.” goes before the number. “A.D. 2013” = “The Year of the Lord 2013,” which is an intelligible phrase. If you write “2013 A.D.” that would be “2013 the Year of the Lord,” which is gibberish.)

So what year was Jesus born?

 

1 B.C.?

The guy who developed the way we reckon years was a 6th-century monk named Dionysius Exiguus (“Dennis the Short”).

He apparently thought Christ was born in 1 B.C. (actually, it’s a bit more complex than that, but we’ll keep this simple).

Today most think this date is a little too late and that the evidence supports a date a few years earlier.

 

6-7 B.C.?

For a little more than a century, the idea has been popular that Jesus was born in 6-7 B.C.

The reasoning goes like this: Jesus was born late in the reign of Herod the Great, who died in 4 B.C.

Furthermore, the wise men saw the star rise in the east two years before they came to visit Jerusalem, where they met Herod.

Back up two years from 4 B.C. and you get 6 B.C.

Back up another year in case Herod didn’t die immediately after they visited, and you get 7 B.C.

So: 6 or 7 B.C.

The problem, as we saw in a previous post, is that the arguments that Herod died in 4 B.C. are exceptionally weak.

 

3-4 B.C.?

Let’s take the same logic as above and plug in the more likely date of Herod’s death.

As we saw in a previous post, the evidence points to him dying in 1 B.C.

So . . . back up two years from that and you get 3 B.C.

Back up another year for cushion and you get 4 B.C.

Thus: 3-4 B.C.

That’s not an unreasonable estimate, but there are two problems with it:

1. It’s got a couple of problematic assumptions.
2. Other evidence, including other evidence from the Bible, suggests it’s a little too early.

The problematic assumptions are that the star was first visible in the east at the moment of Jesus’ birth and that it was visible for a full two years prior to the magi’s arrival.

The first of these assumptions is problematic (among other reasons) because its appearance could be connected with another point in Jesus’ life, such as his conception. If that were the case, you’d need to shave nine months off to find the point of his birth.

It’s also problematic because Matthew doesn’t say that the star appeared two years earlier. What he says is that Herod killed all the baby boys in Bethlehem that were two years old and under, in accord with the time he learned from the magi.

That means that there is some approximating going on here.

Herod would certainly want to make sure the child was dead, and he would err on the side of . . . well, the side of caution from his perspective.

That is, he would to some degree over-estimate how old the child might be in order to be sure of wiping him out.

Thus all the boys two and under were killed.

That means Jesus was at most two years old, but he was likely younger than that.

What may well have happened is Herod may have been told that the star appeared a year ago and he decided to kill all the boys a year on either side of this to make sure of getting the right one.

And then there’s the fact that the ancients often counted parts of a year as a full year in their reckoning, so “two years” might mean “one year plus part of a second year.”

All this suggests that two years was the maximum amount of time earlier that Jesus was born, and likely it was less than that.

Thus . . .

 

2-3 B.C.?

This date would be indicated if we start with Herod’s death in 1 B.C. and then, taking into account the factors named above, backed up only one year, suggesting 2 B.C.

Then, if we back up another year to allow for the fact Herod didn’t die immediately, that would suggest 3 B.C.

So, sometime between 2-3 B.C. would be reasonable, based on what we read in Matthew.

Do we have other evidence suggesting this date?

We do.

Both inside and outside the Bible.

 

The Gospel of Luke

Although Luke offers some helpful clues about the timing of Jesus’ birth, we don’t know enough to make full use of them.

The date of the enrollment ordered by Augustus is notoriously controversial, for example, and too complex to go into here.

However, later indications he gives in his gospel are quite interesting.

He records, for example, that John the Baptist began his ministry in “the fifteenth year of Tiberius Caesar” (3:1).

Tiberius became emperor after Augustus died in August of A.D. 14. Roman historians (e.g., Tacitus, Suetonius), however, tended to skip part years and begin counting an emperor’s reign with the first January 1 after they took office.

On that reckoning, the fifteenth year of Tiberius Caesar would correspond to what we call A.D. 29. (Remember, the 15th year is the time between the completion of the 14th year and the completion of the 15th year, the same way a child’s first year is the time between his birth and his first birthday.)

Jesus’ ministry starts somewhat after John’s, but it doesn’t appear to be very long. Perhaps only a few weeks or months.

If so, Jesus’ ministry also likely started in A.D. 29.

That’s important, because Luke gives us a second clue: He says Jesus was “about thirty years of age” when he began his ministry (3:23).

So, if you take A.D. 29 and back up thirty years, when does that land you?

You might think in 1 B.C., but remember that there’s no Year Zero, so it would actually be 2 B.C.

Or the end of 3 B.C. if Luke was counting Tiberius’s reign from when he became emperor rather than from the next January 1.

Thus: 2-3 B.C. is a reasonable estimate.

That’s still only an estimate, though, because Jesus could have been a little less or a little more than thirty.

(For purposes of comparison, note that when Luke describes the age of Jairus’s daughter, he says she was “about twelve”; 8:42. So Luke doesn’t seem to go in for rounding things to the nearest 5 years; he tries to be more precise than that. When Luke says Jesus was “about thirty,” he’s probably not envisioning anything between 25 and 35 but a range narrower than that.)

To confirm our estimate, it would be nice if we had an exact naming of the year Jesus was born, and in fact we do . . .

 

The Fathers Know Best

There is a startling consensus among early Christian sources about the year of Jesus’ birth.

Here is a table adapted from Jack Finegan’s excellent Handbook of Biblical Chronology (p. 291) giving the dates proposed by different sources:

As you can see, except for a few outliers (including our influential friend, Dionysius Exiguus), there is strong support for Jesus being born in either 3 or 2 B.C.

And note that some of the sources in this table are quite ancient. Irenaeus of Lyon, Clement of Alexandria, Tertullian, Julius Africanus, and Hippolytus of Rome all wrote in the late 100s or early 200s.

We thus have strong indication–from a careful reading of Matthew, from Luke, and from the Church Fathers–that Jesus was born in 3 or 2 B.C.

You might think that Jesus was born in the Year Zero–between 1 B.C. and A.D. 1.

You often hear that Jesus was born around 6-7 B.C.

The evidence from the Bible and the Church Fathers, however, support a different year.

Thus there is no Year Zero between 1 B.C. and A.D. 1.

(BTW, please note that the “A.D.” goes before the number. “A.D. 2013” = “The Year of the Lord 2013,” which is an intelligible phrase. If you write “2013 A.D.” that would be “2013 the Year of the Lord,” which is gibberish.)

On that reckoning, the fifteenth year of Tiberius Caesar would correspond to what we call A.D. 29. (Remember, the 15th year is the time between the completion of the 14th year and the completion of the 15th year, the same way a child’s first year is the time between his birth and his first birthday.)

Jesus’ ministry starts somewhat after John’s, but it doesn’t appear to be very long. Perhaps only a few weeks or months.

The Gospel of Matthew tells us that Jesus Christ was born in the final years of the tyrant known as Herod the Great.

He tells us that when Jesus was born, Herod panicked and had all the baby boys in Bethlehem killed.

Fortunately, the Holy Family escaped to Egypt and remained there until Herod was dead.

They didn’t have to stay long, though.

Here’s when Herod the Great actually died . . .

 

Setting Aside a Common Mistake

For just over a hundred years, the question of when Herod the Great died has been dominated by a proposal by the German scholar Emil Schurer.

He suggested that Herod died in 4 B.C., and this view took off in scholarly circles.

But in recent decades, it’s been challenged and, as we saw in a previous post, the arguments for this position are exceptionally weak.

So when did Herod actually die?

 

The Length of Herod’s Reign

Here is how the Jewish historian Josephus describes the timing of Herod’s death:

So Herod, having survived the slaughter of his son [Antipater] five days, died, having reigned thirty-four years, since he had caused Antigonus to be slain, and obtained his kingdom; but thirty-seven years since he had been made king by the Romans [War of the Jews, 1:33:8 (665); cf. Antiquities of the Jews 17:8:1 (191)].

In this place, Josephus dates Herod’s death by three events:

1. Five days after the execution of his son Antipater.
2. Thirty-four years after he “obtained his kingdom” (i.e., conquered Jerusalem and had its Hasmonean king, Antigonus, killed).
3. Thirty-seven years after “he had been made king by the Romans.”

The death of Antipater isn’t a particularly helpful clue, but the two ways of reckoning the length of his reign are.

First, though, we need to answer one question . . .

 

How Is Josephus Counting Years?

Kings don’t tend to come into office on New Year’s Day, and so they often serve a partial year before the next calendar year begins (regardless of which calendar is used).

They also don’t die on the last day of the year, typically, so they also serve a partial year at the end of their reigns.

This creates complications for historians, because ancient authors sometimes count these additional part-years (especially the one at the beginning of the reign) as a full year.

Or they ignore the calendar year and treat the time that a king came into office as a kind of birthday and reckon his reign in years from that point.

What scheme was Josephus using?

Advocates of the idea that Herod died in 4 B.C. argue that he was named king in 40 B.C. To square that with a 37-year reign ending in 4. B.C., they must count the part year at the beginning of his reign and the part year at the end of it as years. That’s the only way the math will work out.

The problem is that this is not how Josephus would have reckoned the years.

Biblical chronology scholar Andrew E. Steinmann comments:

[T]here is no evidence for this [inclusive way of reckoning the partial years]–and every other reign in this period, including those of the Jewish high priests, are reckoned non-inclusively by Josephus [From Abraham to Paul, 223].

In other words, Josephus does not count the partial first year when dating reigns in this period.

Knowing that, what would we make of Josephus’s two ways of dating Herod’s reign?

 

Herod Appointed King

As we saw in the previous post, Josephus gave an impossible date (one that did not exist) for Herod’s appointment as king.

He said it was in the 184th Olympiad, which ended in midyear 40 B.C. and that it was in the consulship of Calvinus and Pollio, which began in late 40 and extended into 39.

Those can’t both be right, but one of them could be.

Which?

The evidence points to 39 B.C., because we have another source on this: The Roman historians Appian and Dio Cassius.

Appian wrote a history of the Roman civil wars in which he discusses the appointment of Herod in the midst of other events.

By comparing this set of events to how they are dated in Dio Cassius’s Roman History, it can be shown that the events in question–including the appointment of Herod–took place in 39 B.C.

Given how Josephus dates reigns in this period, he would not have counted Herod’s partial first year in 39 B.C. but would have started his count with 38 B.C.

Count 37 years forward from that and you have 1 B.C.

 

Herod Conquers Jerusalem

As we saw in the previous post, Josephus gives contradictory dating information for Herod’s conquest of Jerusalem.

Some of the dating information he provides points to 37 B.C. and some points to 36 B.C.

Josephus said Herod died 34 years after the event.

Bearing in mind that Josephus wasn’t counting partial first years, that would put Herod’s death either in 2 B.C. (if he conquered Jerusalem in 37) or in 1 B.C. (if he conquered the city in 36).

There are various ways to try to resolve which, but some are rather complex.

At least one, however, is quite straightforward . . .

 

Herod’s Lunar Eclipse

We saw in the previous post that Josephus said Herod died between a lunar eclipse and Passover.

While there was a partial lunar eclipsed before Passover in 4 B.C. there was a total lunar eclipse before Passover in 1 B.C.

Further, the lunar eclipse in 1 B.C. better fits the situation Josephus describes (see the previous post for details).

Since 4 B.C. is outside the range indicated above, and since the 1 B.C. lunar eclipse fits the situation better, that lets us decide between 2 B.C. and 1 B.C. in favor of the latter.

There was no lunar eclipse in 2 B.C., pointing us toward 1 B.C.

 

Final Answer?

Putting together the pieces above, we have:

• Reason to think Herod died in 1 B.C. based on the amount of time he served after being appointed king by the Romans.
• Reason to think Herod died in either 2 or 1 B.C. based on the amount of time he served after conquering Jerusalem.
• Reason to think Herod died in 1 B.C. because of the lunar eclipse that occurred before Passover.

More specifically, he would have died between January 10, 1 B.C. (the date of the lunar eclipse) and April 11, 1 B.C. (the date of Passover).

Most likely, it was closer to the latter date, since Josephus records a bunch of things Herod did after the eclipse and before his death, some of which required significant travel time.

There is also one more reason that we should reject the death of Herod in 4 B.C. in favor of a 1 B.C. date . . .

 

We Know When Jesus Was Born

We don’t have to restrict our knowledge of when Herod died to the sources and events mentioned above.

We can also date his death relative to the birth of Christ.

For some reason, moderns seem to think that the dating of Herod’s death should govern when Jesus was born, but the logic works both ways: If we know when Jesus was born, that tells us something about when Herod died.

And we, in fact, have quite good information about the year in which Jesus was born.

It was after 4 B.C., ruling out that date.

So . . . what year was Jesus born?

Stay tuned . . .
