@37818 and I argue over small things because we are united in large thingsExactly...but Christians are so all fire set on arguing about things like this. There's no clear indication about what day he died...let's keep our eyes on the ball and stop arguing over minors when there are so many MAJOR things that are before us..
These arguments are basically for the sake of arguing.
We can't know without doubt the exact date because we do not know when the month started (we do not have a Sanhedrin record) so we apply the Biblical calendar which was not used in the 1st Century.
And then there are other possibilities, like the two Seder meals (the traditional meal and the meal sojourners and the diaspora observed).
And we have Jewish laws affecting when the Passover was sacrificed, depending on what day it fell on.
So it is a meaningless argument. But it's entertaining, and to be fair drives one back into the Scriptures.
