Prophetic period · 457 BC – AD 34
The 70 weeks — 490 years
Seventy sevens measured off from a decree to restore Jerusalem, ending inside the first century — the first slice of a longer measurement.
See it
One long line, cut into 7, 62 and 1. Each cut lands on something the text names: the street and the wall rebuilt, Messiah anointed, the sacrifice ceasing, the gospel going beyond Jerusalem.
Why a day is a year
The measuring rule is given inside Scripture itself — “each day for a year” (Numbers 14:34), “I have appointed thee each day for a year” (Ezekiel 4:6). So 490 days reads as 490 years, and the reading is not a device invented to make the sums work: it is applied because the Bible supplies it.
Which decree, and why the fourth
Four Persian decrees touch the return: Cyrus (536 BC) and Darius (519 BC) authorise the temple; Artaxerxes' seventh year (457 BC) restores Jerusalem's civil life — treasury, judges, magistrates, laws (Ezra 7:11-26); his twentieth year (444 BC) merely permits Nehemiah to rebuild the wall. Daniel 9:25 asks for the commandment “to restore and to build Jerusalem,” a city and not only a sanctuary. Only 457 BC both restores the city and makes the arithmetic land on the Messiah.
Cut off from the 2300
The Hebrew word translated “determined” in verse 24 carries the sense of being cut off — a shorter piece measured from something longer. The only measurement in view is the 2300 evenings-mornings of the previous chapter, the very number Gabriel came back to explain. That is why both periods share 457 BC as their starting point.
Where the numbers land
483 years from autumn 457 BC reaches AD 27 — the baptism, where Jesus is anointed with the Spirit and begins preaching “the time is fulfilled” (Mark 1:15). Three and a half years later, spring AD 31, the cross tears the temple veil and the sacrifices lose their meaning. Three and a half years after that, AD 34, Stephen falls and the gospel turns to the Gentiles — the 490 close on the hour.
Unbroken
Seventy weeks are determined as one continuous period. Nothing in the passage removes the last seven years from the other sixty-nine, and a measurement with an unmeasured hole in the middle is no longer a measurement. The prophecy's own subject — Messiah — fills the final week; there is nothing left over for a future antichrist to occupy.
