The Seventy Weeks
When was the Messiah supposed to die? A prophecy named a year. Astronomy confirmed it.
Prophecy is the most honest test a religion can offer
If the future is genuinely open, prophecy is impossible. Lucky guesses happen, but writing down a verifiable claim and having it land centuries later is a different kind of event.
So let us test one. Daniel chapter 9 contains what is usually called the Seventy Weeks prophecy. It states, in numbers, when the Messiah would appear and when he would be cut off. It asks for no religious sentiment. A calculator and an astronomical table are enough.
The text
Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary…
Three things are specified.
A decree to rebuild Jerusalem.
7 weeks + 62 weeks = 69 weeks.
The Messiah appears, and afterward is cut off.
Why “weeks” means years
The Hebrew word is shavua (שָבוּע), meaning “a unit of seven.” It can mean seven days or seven years. The word alone does not decide.
Daniel decides it himself. In Daniel 10:2 he says he mourned “three full weeks” — and there, uniquely, the Hebrew adds the word yamim, “days”: literally weeks of days. He does not add it in chapter 9.
In other words, Daniel marked the unit when he meant days. Chapter 9 is unmarked.
The context agrees. Daniel 9 opens with Daniel meditating on Jeremiah’s prophecy of seventy years (Daniel 9:2). A man thinking in years was answered in sevens of years.
The starting point: one decree out of four
Scripture records four Persian decrees connected to the return.
| Decree | Date | Concerns |
|---|---|---|
| Cyrus (Ezra 1:1–4) | 538 BC | the temple |
| Darius (Ezra 6:1–12) | 520 BC | the temple |
| Artaxerxes, 7th year (Ezra 7:11–26) | 458 BC | temple worship |
| Artaxerxes, 20th year (Nehemiah 2:1–8) | 445/444 BC | the city and its wall |
Daniel did not say temple. He said “the street… and the wall” (9:25). That is a city, not a sanctuary. Only the fourth decree qualifies.
Nehemiah 2:1 dates it to “the month Nisan, in the twentieth year of Artaxerxes.” Artaxerxes I came to the throne in 465 BC, so his twentieth year falls in 445 or 444 BC, depending on whether the years are counted the Persian way or the Jewish way.
We will leave that one-year uncertainty open. It turns out not to matter.
A prophetic year is 360 days
This is not a rule invented to make Daniel work. Scripture fixes it twice, at both ends of the canon.
The flood begins on the seventeenth day of the second month (7:11) and the ark rests on the seventeenth day of the seventh month (8:4). Between them, Scripture counts 150 days (7:24, 8:3).
Five months, 150 days — thirty days to a month.
The same span is called forty-two months (11:2, 13:5) and 1,260 days (11:3, 12:6).
Forty-two thirty-day months make exactly 1,260. No other month length works.
The first book of the Bible and the last use the same unit.
The calculation
There is no year zero between 1 BC and AD 1, so one year is subtracted in crossing over.
Daniel’s prophecy therefore points to the window AD 32–33. Now the test begins.
Astronomy narrows it to one year
Jesus died at Passover — Nisan 14 — and that day was a Friday. But the phases of the moon can be computed. Reconstructing Nisan 14 across Pilate’s governorship (AD 26–36) gives this.
| Year | Nisan 14 (Julian) | Day |
|---|---|---|
| AD 30 | 7 April | Friday |
| AD 31 | 27 March | Tuesday |
| AD 32 | 14 April | Monday |
| AD 33 | 3 April | Friday |
| AD 34 | 24 March | Wednesday |
Only AD 30 and AD 33 have a Friday Passover. Overlay the two constraints.
Daniel is a sixth-century BC Hebrew document. The lunar reconstruction is twentieth-century physics. Neither consults the other.
This also means the widely quoted “AD 32” calculation cannot stand. Passover in AD 32 fell on a Monday. The classic works that produced that date need correcting on this point, and it is better to say so plainly than to be corrected later.
And the second half of verse 26
Daniel also recorded what would happen after the Messiah was cut off.
…and the people of the prince that shall come shall destroy the city and the sanctuary…
In AD 70 the legions of Titus took Jerusalem and burned the temple. It has never been rebuilt.
Note the order. The Messiah is cut off first; the temple falls afterward. Daniel did not reverse it — which places a deadline on the whole prophecy. No candidate appearing after AD 70 can satisfy it.
A Jewish man who met Jesus through this calculation
Jacob Damkani was a disillusioned young Israeli with no interest in religion. A Christian opened Daniel 9 in front of him — his own nation’s scripture, read in his own synagogue — and he found a calculation whose endpoint carried a name his people had refused for two thousand years.
He now runs a ministry taking that name to the people most determined to reject it.
Could this be coincidence?
Daniel was written centuries before Jesus. It fixes a starting point and a duration. The result lands on the only year astronomy allows.
And in that year, a man was received into Jerusalem as a king and executed days later, having gained nothing.
“Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.”
The deep dive examines each element against the Hebrew text and the historical sources, and answers five standard objections in full.
