Mark 14:12  And on the first day of unleavened bread,  when they sacrificed the Passover  {14th day of 1st month}, his disciples say unto him, Where wilt thou that we go and make ready that thou mayest eat the Passover?   13  And he sendeth two of his disciples, and saith unto them, Go into the city, and there shall meet you a man bearing a pitcher of water: follow him;  14  and wheresoever he shall enter in, say to the master of the house, The Teacher saith, Where is my guest-chamber, where I  shall  eat the Passover with my disciples?     15  And he will himself show you a large upper room furnished and ready: and there make ready for us.   16  And the disciples went forth, and came into the city, and found as he had said unto them: and they made ready the Passover17  And when it was evening  {15th day of 1st month, began at sunset} he cometh with the twelve.   18  And as they sat and were eating, Jesus said, ……..

Luke 22:7  And the day of unleavened bread came  on which the Passover must be sacrificed  {14th day of 1st month}.   8  And he sent Peter and John, saying, Go and make ready for us the Passover, that we may eat.   9  And they said unto him, Where wilt thou that we make ready?   10  And he said unto them, Behold, when ye are entered into the city, there shall meet you a man bearing a pitcher of water; follow him into the house whereinto he goeth.   11  And ye shall say unto the master of the house, The Teacher saith unto thee, Where is the guest-chamber, where I  shall  eat the Passover with my disciples?   12  And he will show you a large upper room furnished: there make ready.   13  And they went, and found as he had said unto them: and they made ready the Passover.   14  And when the hour was come, he sat down, and the apostles with him.   15  And he said unto them,  With desire I have desired  to eat  this Passover  with you  before I suffer: ......

Matt 26:17  Now on the first day of unleavened bread the disciples came to Jesus, saying, Where wilt thou that we make ready for thee to eat the Passover?   18  And he said, Go into the city to such a man, and say unto him, The Teacher saith, My time is at hand; I keep the Passover at thy house with my disciples.   19  And the disciples did as Jesus appointed them; and they made ready the Passover.   20  Now when even was come, he was sitting at meat with the twelve disciples;   21  and as they were eating, he said,

After ate with apostles and instituted Lord’s Supper:

Mark 14:26  And when they had sung a hymn, they went out unto the mount of Olives. ….   32  And they come unto a place which was named Gethsemane: and he saith unto his disciples, Sit ye here, while I pray.
….  43  And straightway, while he yet spake, cometh Judas, one of the twelve, and with him a multitude with swords and staves, from the chief priests and the scribes and the elders. ….  53  And they led Jesus away to the high priest:  and there come together with him all the chief priests and the elders and the scribes.  54  And Peter had followed him afar off, …. 72  …. And Peter called to mind the word, how that Jesus said unto him, Before the cock crow twice, thou shalt deny me thrice. And when he thought thereon, he wept.  Mark 15:1  And straightway in the morning the chief priests with the elders and scribes, and the whole council, held a consultation, and bound Jesus, and carried him away, and delivered him up to Pilate  .…  24  and they crucify him, ….  42  and when even was now come, because it was the Preparation {Friday}, that is, the day before the sabbath,  43  there came Joseph of Arimathaea, …. and asked for the body of Jesus. … 45 …. he granted the corpse to Joseph.  46 …. laid him in a tomb which had been hewn out of a rock; and he rolled a stone against the door of the tomb. … Mark 16:1  And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, bought spices, that they might come and anoint him.   2  And very early on the 1st day of the week, they come to the tomb when the sun was risen.

Luke 24:1  But on the  1st day  of the week, at early dawn, they came unto the tomb,…  6 … He is not here, but is risen:…  13  and behold, two of them were going  that very day  to a village ….  21  Yea and besides all this,  it is now the 3rd day  since these things came to pass. ….

John 18:28  Then led they Jesus from Caiaphas unto the hall of judgment: and it was early; and they themselves went not into the judgment hall, lest they should be defiled; but that they might eat the Passover.

Matt 26:17-21, Mk 14:12-15:42, & Lk 22:7-15    PROVE    Jesus ate the Passover lamb at the usual time and manner, and was crucified on the 15th.  The  only  passage which has led to a contrary opinion is this verse in John;  but here the word Passover does not necessarily mean the paschal lamb.  It may, and I think does, refer to the 7-day Feast of unleavened bread which followed the sacrifice of the lamb (Num 28:16-17).  This whole 7-day feast was also called the Passover  (Ezek 45:21, Lk 22:1).   Even though the paschal lamb had been killed, they were unwilling to defile themselves, because it would disqualify them from participating in the remainder of the ceremonies (daily sacrifices, etc.) during that week.

John 19:14  And it was the preparation of the Passover  {day of preparation (Friday) during Passover week, the 7 day feast of unleavened bread > Lk 22:1 “Now the feast of unleavened bread drew nigh, which is called the Passover“},  and about the sixth hour: and he saith unto the Jews, Behold your King! ….  18  … they crucified him, and two other with him,…. 19:30 … Jesus …. gave up the ghost.   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, {sabbath day during the time of the feast})  besought Pilate that their legs might be broken, ….. 41  Now in the place where he was crucified there was a garden; and in the garden a new sepulchre, wherein was never man yet laid.   42  There laid they Jesus therefore because of the Jews' preparation day {Friday};  for the sepulchre was nigh at hand.

The preparation day in these verses  CANNOT  BE  the day of preparation for the Passover, because on that day Jesus was alive and sent his disciples to prepare for the Passover - again, see verses above. 

It WAS the day of preparation (Friday) for the weekly Sabbath (Saturday).


Various 7th Day groups and some brethren say:

Jesus had to die on the 14th of the 1st month, at the same time the Passover lamb was sacrificed…

From this idea and John 18:28 they conclude the meal Jesus ate with his disciples was not, and could not have been, the Passover meal…

The following material examines that contention, showing that Jesus WAS NOT crucified on the 14th, that he DID eat the Passover meal with his disciples and was crucified ON the 15th.  We also see that the 15th (the day he was crucified and buried) was the day before the Sabbath (what we call Friday), that he was raised on the 1st day, and that period of time is called 3 days  or  3 days and 3 nights.

First, note how some terms are used, or some definitions: 

The word  Passover  is used in at least two senses…

1. Both the Lamb which is killed  and  the day they killed it  are called the Passover…….


Ex 12:21  Then Moses called for all the elders of Israel, and said unto them, Draw out, and take you lambs according to your families, and kill the Passover.  

Num 28:16  And in the first month, on the fourteenth day of the month, is Jehovah's Passover.   

Mark 14:12  And on the first day of unleavened bread,  when they  sacrificed the Passover, …….


2. The 7-Day Feast of Unleavened Bread is also  called  the Passover….

 
Ezek 45:21  In the first month, in the fourteenth day of the month, ye shall have the Passover, a feast of seven days; unleavened bread shall be eaten.

 
Luke 22:1  Now the feast of unleavened bread drew nigh, which is called the Passover.


According to the Law, the 14th was the day of preparation for the Jewish Passover and was the day they killed the Passover lamb. They were to eat it during the night/evening (the 15th, began at sunset) which was the 1st day of the 7-day feast of unleavened bread, called the Passover.  (See chart/timeline below.)

Various 7th Day groups  >  Herbert W. Armstrong,   7th Day  Adventists,   7th Day Baptists,   and others,   including Mr. Dart from a group which broke off from Armstrong (was on local radio),    [and  some  brethren ]  say:  Jesus had to and did die on the 14th at the same time they killed the Passover Lamb and was buried before sundown that same day. The next day (15th) was the 1st day of Passover (feast of unleavened bread),  the day  they were to eat the Passover lamb (they say, Jesus did not eat the Passover).  They contend the 15th was a high day (because were to do no work).  DART says the 14th was on Wednesday. He says Jesus was buried, late on that day, and was Resurrection 3 days later on the Sabbath [Saturday the 16th]……

(What Day was He Crucified & Raised, How long in the tomb/3 days & 3 nights) 

Jesus' Crucifixion, Burial, and Resurrection

WE  REPEAT  THE  BIBLE  TEACHES:

Jesus was crucified on Friday and resurrected on Sunday.
He was raised after 3 days, the Sunday he was resurrected was the 3rd day,
and that time period is called 3 days and 3 nights.

Jesus was crucified on Friday and resurrected on Sunday.

Scripture tells us he was raised after 3 days,  Sunday was the 3rd day,

and also calls this time period 3 days and 3 nights.

Here's a chart illustrating Jesus' crucifixion, burial and resurrection.

One final note on the 3 days & 3 nights and expressing time:
