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 city rebuilt, Messiah anointed, the sacrifice ceasing.
Why a day is a year
The measuring rule is given inside Scripture itself — a day for a year — which is why 490 days reads as 490 years and lands on datable events.
Unbroken
Seventy weeks are “determined” as one continuous period; nothing in the passage removes the last seven years from the other sixty-nine.
