A number of approaches have been used to estimate the year of the death of Jesus, including information from the canonical gospels, the chronology of the life of Paul the Apostle in the New Testament correlated with historical events, as well as different astronomical models, as discussed below.
The four gospels report that Jesus was crucified by Pontius Pilate, who governed Roman Judea from 26 to 36 AD/CE. Jewish historian Josephus,[81] writing in Antiquities of the Jews (c. 93 AD/CE), and the early 2nd century Roman historian Tacitus,[82] writing in The Annals (c. 116 AD/CE), also state that Pilate ordered the execution of Jesus.[83]
The estimation of the date of the conversion of Paul places the death of Jesus before this conversion, which is estimated at around 33-36 AD/CE.[84][85][86] The estimation of the year of Paul's conversion relies on a series of calculations working backwards from the well established date of his trial before Gallio in Achaea, Greece, (Acts 18:12-17) around 51-52 AD/CE, the meeting with Priscilla and Aquila who may have been expelled from Rome about 49 AD/CE and the 14-year period before returning to Jerusalem in Galatians 2:1.[84][85][86] The remaining period is generally accounted for by Paul's missions such as those in Acts 11:25-26 and 2 Corinthians 11:23-33, resulting in the 33-36 AD/CE estimate.[84][85][86]
Isaac Newton was one of the first astronomers to estimate the date of the crucifixion and suggested Friday, April 3, 34 AD/CE.[87][88] In 1990 astronomer Bradley E. Schaefer computed the date as Friday, April 3, 33 AD/CE.[89] In 1991, John Pratt stated that Newton's method was sound, but included a minor error at the end. Pratt suggested the year 33 AD/CE as the answer.[87] Using the completely different approach of a lunar eclipse model, Humphreys and Waddington arrived at the conclusion that Friday, April 3, 33 AD/CE was the date of the crucifixion.[90][91][92]
