So which year was Christ crucified? 30AD or 33AD? Please show your math.
If all you are looking for is a reconciliation of Daniel's prophecy of 483 years to the "cutting off but not for himself", here it is:
Ezra 7:11-26 records the decree of Artaxerxes Longimanus directing return and reconstruction to proceed. Ezra tells us that decree was rendered prior to the seventh year of Artaxerxes Longimanus (because Ezra also tells us in 7:9 that he commenced his journey pursuant to the decree on the first day of the first month of the seventh year).
Artaxerxes Longimanus is credited by Persian historical records with a reign from 464 BC to 424 BC however that term is derived from Persian records which count a reign from the year in which the individual first begins to serve, even in a co-regency; or other capacity.
Longimanus was the son of Xerxes.
Although it is clear that Xerxes was murdered in 464 BC by Artabanus, a Hyrcanian usurper, it is also clear that Artabanus served as King for some period thereafter, probably into August of 461 BC when he was slain by Longimanius.
The Jews counted co-regencies and disputed reigns as separate reigns; and counted regency from the first day of the first full year in which the reign commenced. Thus for purposes of the Jewish book recounting in Ezra, Longimanus would commence his reign on the first day of the year which commenced in the spring (after the vernal equinox in March) of 460 BC. Thus his seventh year was the year beginning 453; so assuming the decree of Ezra 7:11 was rendered in the year prior to the year which began on the day on which he started to go to Jerusalem, 454 BC., then: 454 BC to 30 AD = 484 - 1 year (no year 0) is 483 years to the date of cruxification of Jesus Christ on April 5, 30 AD.
