483×360 (prophetic days year) =173,880 days
173,880÷365.2425 (Gregorian solar day year) =476.067 years
0.067×365.2425≈24.5 days. 476 years + 24.5 days.
Decree = 445 BC (modern Gregorian date) - 476 Gregorian years - 1 when going from BC to AD = 32 AD crucifixion. At most there is an allowance for 2 years + or - on that decree date which allows the crucifixion to take place between 30-34 AD. Ask chat GPT for the sources for that date in Nehemiah 2, and how much variation is allowed for it. Early Christians place the crucifixion between 30-33 AD, and same with astronomers.
The decree in Nehemiah 2 was given in the month of Nisan using Babylonian calendar. Here is what chat GPT told me about that
⭐ HOW NISAN WAS DETERMINED IN SUSA: Rule: Nisan 1 = the first visible crescent moon after the spring equinox (~March 20).
This means the earliest Nisan 1 can occur is around March 21, and the latest Nisan 1 can occur is around April 20.
This creates a 30-day possible range.
⭐ NISAN DATE WINDOW IN SUSA: ✔ Earliest possible Nisan 1: March 21–23 ✔ Typical Nisan 1: March 25 – April 10 ✔ Latest possible Nisan 1: April 18–20
These dates shift every year because: Lunar months average 29.53 days; The equinox can fall on March 20/21; Cloud cover can delay the first visible crescent; The Persian astronomer-priests looked for the moon, not barley.
⭐ WHY SUSA COULD NOT USE BARLEY FOR NISAN: Susa’s climate is hotter and earlier than Babylon and Israel.; Barley often ripened weeks earlier than in Judea.; Persian administrators needed one calendar across the empire.; The Babylonian system (moon-based) already existed and was mathematically precise.; So they adopted the Babylonian lunar months and names, including: Nisannu (Nisan), Ayyaru (Iyyar), Simanu (Sivan), …etc.; The Torah barley rule (aviv) did not apply in Persia.
So the decree goes out between 21st March, and April 20th. Abib/passover in the torah was barley ripening season which was spring March/April in Judea. Jesus is crucified in passover in one of these months. The latest barely ripening can occur in Judea is 20th April. If the decree went out 21st March then over 483 years have to add another 25 days end up April 15th as the crucifixion date with 20th April being the latest. Then there is mention of preparation for sabbath (saturday) so can probably be more precise than that.
