"52. Was Jesus on the cross (Mark 15:23) or in Pilate's court (John 19:14) at the sixth hour on the day of the crucifixion?
(Category: misunderstood the historical context)
The simple answer to this is that the synoptic writers (Matthew, Mark and Luke) employed a different system of numbering the hours of day to that used by John. The synoptics use the traditional Hebrew system, where the hours were numbered from sunrise (approximately 6:00am in modern reckoning), making the crucifixion about 9:00am, the third hour by this system..
John, on the other hand, uses the Roman civil day. This reckoned the day from midnight to midnight, as we do today. Pliny the Elder (Natural History 2.77) and Macrobius (Saturnalia 1.3) both tell us as much. Thus, by the Roman system employed by John, Jesus' trial by night was in its end stages by the sixth hour (6:00am), which was the first hour of the Hebrew reckoning used in the synoptics. Between this point and the crucifixion, Jesus underwent a brutal flogging and was repeatedly mocked and beaten by the soldiers in the Praetorium (Mark 15:16-20). The crucifixion itself occurred at the third hour in the Hebrew reckoning, which is the ninth in the Roman, or 9:00am by our modern thinking.
This is not just a neat twist to escape a problem, as there is every reason to suppose that John used the Roman system, even though he was just as Jewish as Matthew, Mark and Luke. John's gospel was written after the other three, around AD90, while he was living in Ephesus. This was the capital of the Roman province of Asia, so John would have become used to reckoning the day according to the Roman usage. Further evidence of him doing so is found in John 21:19: 'On the evening of that first day of the week'. This was Sunday evening, which in Hebrew thinking was actually part of the second day, each day beginning at sunset."
