Thanks for the reply Yitzhak. That was the kind of thing I was hoping  
for. I'm not prepared for a detailed response. I'm going to have to  
look into the points you have made a bit further. But, the idea of  
competing calendar systems sounds, in substance, like a worthy lead to  
follow. And I agree that each book should be approached independently.  
This is fundamental to an objective study. And you may be right about  
approaching each part of each book separately. Especially, for  
accounts reported in Genesis which probably survive to the Torah as  
oral traditions handed down from generation to generation.

Thanks again. That was definitely food for thought.

However, I keep calling to mind that Jesus was executed on the  
Preparation of that year, which was a Friday, and asking myself  
whether that was a day 6 of the week because it just fell that way  
that year or whether it fell that way every year. Could it possibly be  
that we have no primary source evidence from that period in Jewish  
history?
