You appear to be accepting the "sign of Jonah" as being perfect. If you examine more details, some of which are not obvious, the only year that fits for the crucifixion is 33. In that specific year, the Passover, according to the Galilean calendar, would fall on a Wednesday night into Thursday, while the official Passover it began on Friday night into Saturday. But also in 33, Pilate was politically isolated. His anti-Jewish patron back in Rome had been moved from office and executed in late 32 for scheming against Tiberius. Pilate was in need of political cover, so actively going against perceived enemies of Rome and able to be pressured by more politically stable individuals fits perfectly And, that is not all that you might have already uncovered. You might even have uncovered that in the spring of 37, Pilate and Caiaphas were both removed from office by Vitellius, the father of the future short-term emperor, and that Antipas escorted Vitellius to the Euphrates where they met with the Parthian emperor and where Antipas was exceedingly gracious to both men, before returning to Jerusalem by himself, only to be exiled two years later when Gaius revoked political pardons he had issued after the death of Tiberius in the spring of 37. But what I would be surprised to learn that you were aware of would be the numismatic evidence from 33-4 that Antipas appears to have supported the early Jesus movement, or that Moses of Chorene claimed to have had access to a letter from Tiberius in which he acknowledged the crucifixion and resurrection of Jesus and the involvement of Pilate, Caiaphas and Antipas in questionable activity, and that the letter also appears to reference specific, relatively obscure, activity from the period 35-6 CE.
If one is truly going to investigate the NT, one must make every possible effort to know what the people of the day knew, and not assume that our common 21sst century knowledge, which is largely ignorant of 1st century commonly known realities, is sufficient. I might add, that to date, I have yet to find another NT scholar who was aware of the numismatic evidence I uncovered before I appraised them of it, but their reaction has consistently been that if I am interpreting it correctly, it changes everything,
