Now when you say Thursday, do you mean Wednesday at sunset?
Hung on pole Thursday, died Thursday afternoon, taken off pole and prepared for burial before sunset.
This daylight day, was the day of preparation for passover, passover begins at sunset, and no work is allowed once this sunset occurs. Therefore, to avoid work on sabbath, Joseph of A. requested body for prep.
Placed in tomb Thursday just before or at sunset, just before special passover sabbath. (note, you will see two "sabbaths" one special one, immediately followed the next day by the regular weekly one. Passover can start on any day, and creates an extra sabbath for that week if it isn't already on a Sabbath.
Sunset Thursday, night #1 is counted in advance and continues ~12 hrs until Friday dawn.
Friday dawn, day #1 is counted in advance and continues ~12 hrs
Friday sunset, night #2 is counted in advance and continues ~12 hrs
Saturday dawn, day #2 is counted in advance and continues ~12 hrs
Saturday sunset, night #3 is counted in advance and continues ~12 hrs
Sunday dawn, day #3 is counted in advance, the moment the sun breaks the horizon and He is risen
(He did not have to stay in there until Sunday sunset, because all 3 nights and 3 days have now been counted properly in hebrew style.)
1 millisecond of visible sun or less is all that would be required to count daybreak as day #3
Hope that makes it clearer. The only "trick" to counting to 3, is whether you count it in advance like they did, or after it is complete the way we must do in scientific calculations.
Counting math/science style would require Him to have gone into the tomb Thursday at dawn in order to squeeze in 3 days and nights before Sunday dawn.
Counting any later than Thursday at sunset, would fall short of 3.0 nights and 2.x (hebrew 3) days.
"And that day was the preparation, and the sabbath drew on." does not refer to the weekly sabbath, but rather the first day of passover, a special sabbath, in this case, "friday". Modern christianity don't usually know this, and so they assume it must have happened all on friday, thinking saturday to be the only sabbath in play.
"And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you. And ye shall observe the feast of unleavened bread"
There can be a regular sabbath any day in between.
And the last supper occurred one evening early, Wednesday at Jesus' own special request. This is no problem, because man was not made for the sabbath, but the sabbath for man.
Scripture fails to record the bread as being unleavened, and even hints somewhere at the opposite in the choice of word used.
I'll even bet the Pharisee high priest cut that lamb's throat right at the moment Yeshua gave His last breath outside the city. And I wonder Thursday night, having seen all that he had seen and the events of the day: if that Pharisee high priest actually ate the lamb or ATE the "Lamb" that night.
There is MUCH more AWESOME detail regarding Yeshua's approach to the city, that only comes to life if you know how they celebrated passover. He hijacked the Pharisee's entry parade where they bring the lamb through the gate to the city. That's why they told His disciples to hush. It was a BIG deal to make that announcement, and they were announcing the "wrong lamb" in religious opinion, this announcement was one that spread person to person by ear-shot across the city, and the disciples basically "pulled the fire alarm."
SO rockin'.
Peace.
