It seems to me that the Son of man was delivered up to the Jews on Thursday and then condemned to be crucified/slain on the next day, Friday.
I think that the day Jesus said the following (Matthew 26:1-2) was on the Tuesday before He died.
Matthew 26:1-25--27:
When Jesus had finished all these sayings (on Tuesday), he said to his disciples, 2 “You know that after two days (today which is Tuesday and tomorrow which is Wednesday) the Passover is coming (on Thursday), and the Son of man will be delivered up (on Thursday night) to be crucified (Friday).”
3 Then (sometime on Wednesday) the chief priests and the elders of the people gathered in the palace of the high priest, who was called Ca′iaphas, 4 and took counsel together in order to arrest Jesus by stealth and kill him. 5 But they said, “Not during the feast, lest there be a tumult among the people.”
6 Now when Jesus was at Bethany in the house of Simon the leper (also sometime on Wednesday), 7 a woman came up to him with an alabaster flask of very expensive ointment, and she poured it on his head, as he sat at table. 8 But when the disciples saw it, they were indignant, saying, “Why this waste? 9 For this ointment might have been sold for a large sum, and given to the poor.” 10 But Jesus, aware of this, said to them, “Why do you trouble the woman? For she has done a beautiful thing to me. 11 For you always have the poor with you, but you will not always have me. 12 In pouring this ointment on my body she has done it to prepare me for burial. 13 Truly, I say to you, wherever this gospel is preached in the whole world, what she has done will be told in memory of her.”
14 Then one of the twelve, who was called Judas Iscariot, went to the chief priests (on this same Wednesday) 15 and said, “What will you give me if I deliver him to you?” And they paid him thirty pieces of silver. 16 And from that moment he sought an opportunity to betray him.
17 Now on the first day of Unleavened Bread (Thursday morning, the next day) the disciples came to Jesus, saying, “Where will you have us prepare for you to eat the passover?” 18 He said, “Go into the city to a certain one, and say to him, ‘The Teacher says, My time is at hand; I will keep the passover at your house with my disciples.’” 19 And the disciples did as Jesus had directed them, and they prepared the passover (on this same Thursday).
20 When it was evening (on this same Thursday), he sat at table with the twelve disciples; 21 and as they were eating, he said, “Truly, I say to you, one of you will betray me.” 22 And they were very sorrowful, and began to say to him one after another, “Is it I, Lord?” 23 He answered, “He who has dipped his hand in the dish with me, will betray me. 24 The Son of man goes as it is written of him, but woe to that man by whom the Son of man is betrayed! It would have been better for that man if he had not been born.” 25 Judas, who betrayed him, said, “Is it I, Master?” He said to him, “You have said so.”
26 Now as they were eating, Jesus took bread, and blessed, and broke it, and gave it to the disciples and said, “Take, eat; this is my body.” 27 And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you; 28 for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. 29 I tell you I shall not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.” 30 And when they had sung a hymn, they went out to the Mount of Olives. 31 Then Jesus said to them, “You will all fall away because of me this night; for it is written, ‘I will strike the shepherd, and the sheep of the flock will be scattered.’ 32 But after I am raised up, I will go before you to Galilee.” 33 Peter declared to him, “Though they all fall away because of you, I will never fall away.” 34 Jesus said to him, “Truly, I say to you, this very night, before the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] crows, you will deny me three times.” 35 Peter said to him, “Even if I must die with you, I will not deny you.” And so said all the disciples.
36 Then Jesus went with them to a place called Gethsem′ane, and he said to his disciples, “Sit here, while I go yonder and pray.” 37 And taking with him Peter and the two sons of Zeb′edee, he began to be sorrowful and troubled. 38 Then he said to them, “My soul is very sorrowful, even to death; remain here, and watch with me.” 39 And going a little farther he fell on his face and prayed, “My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as thou wilt.” 40 And he came to the disciples and found them sleeping; and he said to Peter, “So, could you not watch with me one hour? 41 Watch and pray that you may not enter into temptation; the spirit indeed is willing, but the flesh is weak.” 42 Again, for the second time, he went away and prayed, “My Father, if this cannot pass unless I drink it, thy will be done.” 43 And again he came and found them sleeping, for their eyes were heavy. 44 So, leaving them again, he went away and prayed for the third time, saying the same words. 45 Then he came to the disciples and said to them, “Are you still sleeping and taking your rest? Behold, the hour is at hand, and the Son of man is betrayed into the hands of sinners. 46 Rise, let us be going; see, my betrayer is at hand.”
47 While he was still speaking, Judas came, one of the twelve, and with him a great crowd with swords and clubs, from the chief priests and the elders of the people. 48 Now the betrayer had given them a sign, saying, “The one I shall kiss is the man; seize him.” 49 And he came up to Jesus at once and said, “Hail, Master!” And he kissed him. 50 Jesus said to him, “Friend, why are you here?” Then they came up and laid hands on Jesus and seized him. 51 And behold, one of those who were with Jesus stretched out his hand and drew his sword, and struck the slave of the high priest, and cut off his ear. 52 Then Jesus said to him, “Put your sword back into its place; for all who take the sword will perish by the sword. 53 Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels? 54 But how then should the scriptures be fulfilled, that it must be so?” 55 At that hour Jesus said to the crowds, “Have you come out as against a robber, with swords and clubs to capture me? Day after day I sat in the temple teaching, and you did not seize me. 56 But all this has taken place, that the scriptures of the prophets might be fulfilled.” Then all the disciples forsook him and fled.
57 Then those who had seized Jesus (late on this Thursday night) led him to Ca′iaphas the high priest, where the scribes and the elders had gathered. 58 But Peter followed him at a distance, as far as the courtyard of the high priest, and going inside he sat with the guards to see the end. 59 Now the chief priests and the whole council sought false testimony against Jesus that they might put him to death, 60 but they found none, though many false witnesses came forward. At last two came forward 61 and said, “This fellow said, ‘I am able to destroy the temple of God, and to build it in three days.’” 62 And the high priest stood up and said, “Have you no answer to make? What is it that these men testify against you?” 63 But Jesus was silent. And the high priest said to him, “I adjure you by the living God, tell us if you are the Christ, the Son of God.” 64 Jesus said to him, “You have said so. But I tell you, hereafter you will see the Son of man seated at the right hand of Power, and coming on the clouds of heaven.” 65 Then the high priest tore his robes, and said, “He has uttered blasphemy. Why do we still need witnesses? You have now heard his blasphemy. 66 What is your judgment?” They answered, “He deserves death.” 67 Then they spat in his face, and struck him; and some slapped him, 68 saying, “Prophesy to us, you Christ! Who is it that struck you?”
69 Now Peter was sitting outside in the courtyard. And a maid came up to him, and said, “You also were with Jesus the Galilean.” 70 But he denied it before them all, saying, “I do not know what you mean.” 71 And when he went out to the porch, another maid saw him, and she said to the bystanders, “This man was with Jesus of Nazareth.” 72 And again he denied it with an oath, “I do not know the man.” 73 After a little while the bystanders came up and said to Peter, “Certainly you are also one of them, for your accent betrays you.” 74 Then he began to invoke a curse on himself and to swear, “I do not know the man.” And immediately the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] crowed (very. very early on Friday morning). 75 And Peter remembered the saying of Jesus, “Before the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] crows, you will deny me three times.” And he went out and wept bitterly.
27 When (Friday) morning came, all the chief priests and the elders of the people took counsel against Jesus to put him to death; 2 and they bound him and led him away and delivered him to Pilate the governor.
3 When Judas, his betrayer, saw that he was condemned, he repented and brought back the thirty pieces of silver to the chief priests and the elders, 4 saying, “I have sinned in betraying innocent blood.” They said, “What is that to us? See to it yourself.” 5 And throwing down the pieces of silver in the temple, he departed; and he went and hanged himself. 6 But the chief priests, taking the pieces of silver, said, “It is not lawful to put them into the treasury, since they are blood money.” 7 So they took counsel, and bought with them the potter’s field, to bury strangers in. 8 Therefore that field has been called the Field of Blood to this day. 9 Then was fulfilled what had been spoken by the prophet Jeremiah, saying, “And they took the thirty pieces of silver, the price of him on whom a price had been set by some of the sons of Israel, 10 and they gave them for the potter’s field, as the Lord directed me.”
11 Now Jesus stood before the governor; and the governor asked him, “Are you the King of the Jews?” Jesus said, “You have said so.” 12 But when he was accused by the chief priests and elders, he made no answer. 13 Then Pilate said to him, “Do you not hear how many things they testify against you?” 14 But he gave him no answer, not even to a single charge; so that the governor wondered greatly.
15 Now at the feast the governor was accustomed to release for the crowd any one prisoner whom they wanted. 16 And they had then a notorious prisoner, called Barab′bas. 17 So when they had gathered, Pilate said to them, “Whom do you want me to release for you, Barab′bas or Jesus who is called Christ?” 18 For he knew that it was out of envy that they had delivered him up. 19 Besides, while he was sitting on the judgment seat, his wife sent word to him, “Have nothing to do with that righteous man, for I have suffered much over him today in a dream.” 20 Now the chief priests and the elders persuaded the people to ask for Barab′bas and destroy Jesus. 21 The governor again said to them, “Which of the two do you want me to release for you?” And they said, “Barab′bas.” 22 Pilate said to them, “Then what shall I do with Jesus who is called Christ?” They all said, “Let him be crucified.” 23 And he said, “Why, what evil has he done?” But they shouted all the more, “Let him be crucified.”
24 So when Pilate saw that he was gaining nothing, but rather that a riot was beginning, he took water and washed his hands before the crowd, saying, “I am innocent of this man’s blood; see to it yourselves.” 25 And all the people answered, “His blood be on us and on our children!” 26 Then he released for them Barab′bas, and having scourged Jesus, delivered him to be crucified.
27 Then the soldiers of the governor took Jesus into the praetorium, and they gathered the whole battalion before him. 28 And they stripped him and put a scarlet robe upon him, 29 and plaiting a crown of thorns they put it on his head, and put a reed in his right hand. And kneeling before him they mocked him, saying, “Hail, King of the Jews!” 30 And they spat upon him, and took the reed and struck him on the head. 31 And when they had mocked him, they stripped him of the robe, and put his own clothes on him, and led him away to crucify him.
32 As they went out, they came upon a man of Cyre′ne, Simon by name; this man they compelled to carry his cross. 33 And when they came to a place called Gol′gotha (which means the place of a skull), 34 they offered him wine to drink, mingled with gall; but when he tasted it, he would not drink it. 35 And when they had crucified him, they divided his garments among them by casting lots; 36 then they sat down and kept watch over him there. 37 And over his head they put the charge against him, which read, “This is Jesus the King of the Jews.” 38 Then two robbers were crucified with him, one on the right and one on the left. rsv
It seems to me that Jesus Christ was delivered up to the Jews on Thursday, late evening, and then on Friday morning He was condemned to be crucified that same day.
Was Josephus speaking about only the Passover practices of his own sect of Judaism or was he referring to the Passover practices of all the different sects of Judaism which were active at that time?
Not everything that is written in the early church fathers' writings is correct and it is not doctrine unless it has been proclaimed to be doctrine by the Magisterium of the Church.
