Passover was hence a "sabbath", yet since Jesus specifically declared that he would be in the heart of the earth for three days and nights, there is only one day that Jesus could have died to make three days and nights, and it is Thursday, and as we shall see, the Bible actually points to this day.
Remember -- the Bible says 3 days, not 72 hours. "days" in parlance do not necessarily mean the exact 72 hours.
Jesus could not have died on Wednesday because then he would have been in the tomb for 4 days and night, contradicting scripture. Scripture says that the women prepared spices to anoint Jesus' body on Sunday. They could not do this on Saturday which was sabbath, a day or rest, so if Jesus died on Wednesday, then Passover and Passover sabbath would have been on Thursday, but Friday would have been non-Sabbath -- so why didn't they come on Friday?
The problem is that you are mixing up Saturday-sabbath with Passover-Sabbath.
Passover then was on Friday, which is when we celebrate this sacrifice of Jesus. on Thursday is the day He died and Friday is the day we remember and mourn.
