Yes, I also agree with Marilyn Agee's reply <http://www.fivedoves.com/letters/aug2011/marilyna820.htm> with some modifications:
1. The Lord was indeed crucified on the day of the preparation and died as the sun started setting, before the annual Sabbath called the Feast of Unleavened Bread:
Mark 15:42 And now when the even was come, because it was the preparation, that is, the day before the sabbath,
Luke 23:54 And that day was the preparation, and the sabbath drew on.
John 19:14 And it was the preparation of the passover, and about the sixth hour: and he saith unto the Jews, Behold your King!
John 19:31 The Jews therefore, because it was the preparation, that the bodies should not remain upon the cross on the sabbath day, (for that sabbath day was an high day,) besought Pilate that their legs might be broken, and that they might be taken away.
2. The Passover lamb was killed on the day of preparation (14 Nisan/Abib) as the sun was setting, but only eaten during the night which was the Feast of Unleavened Bread (starting 15 Nisan which is the evening following the day of preparation), which was an Annual Sabbath. Today what we refer to as Passover day, is actually the Feast of Unleavened Bread.
Exodus 12:6 And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening (i.e sunset on 14 Nisan just before the start of 15 Nisan; see Deuteronomy 16:6).
Exodus 12:7 And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it (i.e. the start of = the evening of 15 Nisan).
Deuteronomy 16:6 But at the place which the LORD thy God shall choose to place his name in, there thou shalt sacrifice the passover at even, at the going down of the sun (i.e. it is still 14 Nisan, but just before the start of 15 Nisan), at the season that thou camest forth out of Egypt.
Exodus 12:17 And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.
Exodus 12:18 In the first month, on the fourteenth day of the month at even (i.e. end of 14 Nisan = start of 15 Nisan), ye shall eat unleavened bread, until the one and twentieth day of the month at even (i.e. 7 days from the start of 15 Nisan; end of 21 Nisan = the evening at the start of 22 Nisan).
Leviticus 23:5 In the fourteenth day of the first month at even is the LORD's passover. (i.e. 14 Nisan at sunset = start of 15 Nisan)
Leviticus 23:6 And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
3. The curious thing, is that Matthew 26 reports the Lord and the 12 apostles, kept a Feast of Unleavened Bread apparently one day earlier than the official days mentioned in Mark, Luke and John. We call this the Last Supper. There is a theory that the day of the Last Supper, was the same as the Feast of Unleavened Bread according to the Essene calendar. The Essenes (writers of the Dead Sea Scrolls; possibly also the group that John the Baptist may have been associated with) were the 3rd prominent Jewish religious group, aside from the Pharisees (Torah and Talmud; forerunners of modern Judaism) and Sadducees (Torah only; temple priests). Even if it matched the Essene calendar, the main reason for holding it a day earlier, seems more likely to be that the Lord would have unable to celebrate the Feast of Unleavened bread with the apostles, since he would have been dead by then - so he held it a day earlier (i.e. at the start of 14 Nisan instead of the start of 15 Nisan).
Matthew 26:17 Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover?
Matthew 26:18 And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the passover at thy house with my disciples.
Matthew 26:19 And the disciples did as Jesus had appointed them; and they made ready the passover.
Matthew 26:20 Now when the even was come, he sat down with the twelve.
4. In probable response to an un-recorded question, about whether they would still celebrate another Feast of Unleavened Bread on the next evening, the Lord's response indicates that he would not be alive in the flesh by then. Also it seems, that the Lord will return for His people on some future Passover day.
Matthew 26:29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
5. So to have been placed in the tomb just as the eve signaling the start of the Feast of Unleavened Bread (15 Nisan/Abib), and to spend 3 days and 3 nights in the tomb, and to have been arisen by the morning of the first day of the week (Sunday), then the Lord must have been crucified on Wednesday afternoon (14 Nisan). So he was in the tomb: night (start of 15 Nisan; Wednesday night; Annual Sabbath; Feast of Unleavened Bread) + day (15 Nisan; Thursday morning & afternoon; Annual Sabbath; Feast of Unleavened Bread) + night (16 Nisan; Thursday night) + day (16 Nisan; Friday morning & afternoon) + night (17 Nisan; Friday night; start of weekly Sabbath) + day (17 Nisan; Saturday morning & afternoon; weekly Sabbath).
Matthew 12:40 For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
Matthew 28:1 In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre.
Mark 16:2 And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
Luke 24:1 Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them.
John 20:1 The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulchre, and seeth the stone taken away from the sepulchre.
