Last Supper 'really a day earlier'.
Professor Colin Humphreys, a scientist at the University of Cambridge, has now concluded that the final meal took place on the Wednesday before the crucifixion, a day earlier than previously accepted.
He believes his findings could present a case for finally introducing a fixed date for Easter.
They also present a solution to apparent contradictions in the Gospels and logistical issues relating to the hours before the crucifixion.
In a new book, The Mystery Of The Last Supper, Prof Humphreys uses a combination of historical and astronomical research to address the precise timing of Jesus' final meal.
