Didascalia Apostolorum

And Judas Iscariot, who was one of us, rose up and went his way to betray him. And Judas came with the scribes and with the priests of the people, and betrayed our Lord Jesus.Now this was done on the fourth day of the week. And in the night they seized our Lord Jesus. And the next day, which was the fourth of the week, he remained in ward in the house of Caiaphas the high priest. And on the same day the chiefs of the people were assembled and took counsel against him. And on the next day again, which was the fifth of the week, they brought him to Pilate the governor. And he remained again in the ward with Pilate the night after the fifth day of the week. But when it drew on (towards day) on the Friday, they accused him much before Pilate; and they could show nothing that was true, but gave false witness against him. And they asked him of Pilate to be put to death; and they crucified him on the same Friday.
He suffered, then, at the sixth hour on Friday. And these hours wherein our Lord was crucified were reckoned a day. And afterwards, again, there was darkness for three hours; and it was reckoned a night. And again, from the ninth hour until evening, three hours, (reckoned) a day. And afterwards again (there was) the night of the Sabbath of the Passion.
