Three days and three nights?

Question from moody radio listener: What day of the week did Jesus die? Dr Michael Vanlaningham rephrased the question: Jesus said that it's going to be three days and three nights in the grave and yet people will say: he was in there part of the day Friday, all Saturday and part of the day Sunday, so we don't really have three full days. Listener: I've always been taught that part of the day in the Jewish calendar counts as a whole day. Answer from Dr Michael Vanlaningham: That's correct. That's good. We get that from and I won't read these verses but I will mention them and if you want to jot these down real quick. We get that idea in 1 Samuel 30: 12-13, 2 Chronicles 10: 5, 12, Ester 4:16, Ester 5:1. In Jewish thinking, apparently, any part of the day was counted as that day and so if Jesus is in the grave let's say Friday night, all day Saturday and part of Sunday morning, any part of those days and their thinking factor is the full day. It's pretty clear that he died on the Friday before the Sabbath of Passover week, that Friday would have started the Passover and there he dies then. Friday, where it's the end of his trial, he get's crucified, give or take around nine o'clock in the morning, passes away on the cross around three on Friday, and on Friday that night starts the Sabbath, the first Sabbath of Passover, Saturday, Sunday.
