Dear Ernie, Thank you for asking.  I had in my post my source reference but I apologize if it was not clear.  A man who was an attorney named Rick Larson for many years went through the ancient writings of Josephus, historical documents, astronomy software and put together the timeline in reference to Herod's death.   Even secular scientists are confirming that he is correct.  I know everyone has their own beliefs, opinions, etc. but here it is.   I purchased also his DVD and this man has a passion that is unstoppable to get to the truth!
