Year of death

One of the facts considered by historians to be practically beyond dispute is that Jesus was executed on the orders of the Roman prefect Pontius Pilate. Pilate held this position from 26–36 CE, during which the only years in which Nisan 14 fell on a Friday were 27 CE, 33 CE, 36 CE, and possibly also 30 CE (depending on when the new moon would have been visible in Jerusalem). Different scholars have defended all of these dates. Maximus Monachus, Eusebius, and Cassiodorus recorded the death of Jesus in 31 CE. The 3rd/4th century Roman historian Lactantius states that Jesus was crucified on 11 April 29 CE.
The most commonly cited dates are 7 April 30 CE and 3 April 33 CE. In the Gospel of Luke, it is stated that Jesus was "about 30 years old" when he was baptised by John the Baptist. However, if Jesus' birth was in 6 BCE, then this points to the beginning of the public ministry some time around 26 CE.
Another fact to be considered is Luke's statement that John the Baptist's ministry began in the fifteenth year of the reign of emperor Tiberius (Luke 3:1-2). Tiberius' reign began after Augustus' death on 19 August 14 CE, placing John's appearance in 28 or 29 CE by official Roman reckoning (counting August 14 CE to August 15 CE as the first year), too late for the beginning of Jesus's ministry as calculated above. On the other hand, Tertullian writes in his Adversus Marcionem of a Roman tradition that placed the crucifixion in the twelfth year of Tiberius' rule, i.e. 25 or 26 CE.
Evidence in the Gospel of John points to three separate Passovers during Jesus' ministry, which would tip the scales toward 33 CE. This is strengthened by details of the "reign" of Sejanus in Rome. Sejanus had ordered the suppression of the Jews throughout the empire, and after his death (in 31 CE), Tiberius repealed those laws (in 32 CE). This would fit with the Gospel accounts that seem to indicate that Pilate did not want to crucify Jesus, but was forced into it by the Jewish leaders
