When did Jesus Christ die?

It's impossible to say with any certainty, but the generally accepted time was at Passover in around AD30. We do know, however, that Passover occurred in what we now call April and we know he died on the Friday (some time round the middle of April) at 'the ninth hour' (ie. around 3pm in modern reckoning) and rose again on the following Sunday. Some claim to know the exact date based on Jewish records, or on extrapolating back in time, but as we do not even know the year with any certainty (it could be anything from 27AD - 33 AD) we therefore cannot be absolutely sure of the exact time or date and any claim to be certain about such things is not really based on sound evidence.
30 AD.
