*edit*
Missed this previously:
Now researchers have looked at textual accounts, geological records and astronomical data to find the most likely date for Jesus's death.
Herod the Great, who died in 4 BC, is featured prominantly in the Bible account of Jesus birth. Therefore Jesus was born in 4 BC or earlier. Since Jesus was 30 when he started His ministry and His ministry was approximately three years, Jesus death was earlier than 33 AD.
Herod ordered the deaths of all young males.
What year of his reign did that happen?
Exactly.
The verifiable, the date of his death, beats out the unverifiable. Don't really understand how that effects the clash between traditional and historical dating.
