I constructed the Wednesday through Saturday model using the four gospels.
6pm Tuesday evening to 6pm Wednesday evening - Nisan 14, Passover - Jesus of Nazareth & Co ate evening meal on Tuesday night after which He was arrested, tried, and sentenced to death. He died at 3 pm on Wednesday, the 9th hour. His body was hurriedly placed in a new tomb so that the Passover could be observed. The women carefully noted where His body was laid because they knew it would be either Friday or Sunday before they could perform the customary anointing of It for burial.
6pm Wednesday evening to 6 pm Thursday evening - Nisan 15, first day of Unleavened Bread - A High Sabbath, so called because it occurred same week as the regular Sabbath. One night, one day ...
6 pm Thursday evening to 6 pm Friday evening - Nisan 16, Preparation Day for the weekly Sabbath. On Friday, women disciples prepared fragrant spices to anoint His body, then rested because of the Sabbath. Two nights, two days ...
6pm Friday evening to 6 pm Saturday evening - Nisan 17, weekly Sabbath - Jesus of Nazareth arose at 6 pm, on Saturday. Three nights, three days ...
6 pm Saturday evening to 6 pm Sunday evening - Nisan 18, first day of the week, early Sunday morning, the risen Jesus of Nazareth appeared to women disciples who had come to anoint His dead body, and to others as they walked along a road or sat in a locked room.
This, I believe, is how it happened.
