the sources are history It’s what exhisted then that defined their perceptions which should be of interest especially since this is testimony from a bishop. I’m sure your familiar with the definition of bishop and that no dummy gets to be in that position.

Didascalia Apostolorum
*
-[v. 13] Wherefore, when you fast, pray and intercede for [181]] them that are lost; as we also did when our Savior suffered.* [v. 14]* For while He was yet with us before He suffered, as we were eating the Passover with Him, He said to us: To-day, in this night, one of you will betray me. (p. 88) And we said unto Him, each one of us: Is it I, Lord? And he answered and said to us: He that putteth forth his hand with me into the dish [Mk 14.30; Mt 26.21-23 (Mk 14.18-20)]. And Judas Iscariot, who was one of us, rose up and went his way to betray Him [cf. Jn 13.30]. Then our Lord said to us: Verily I say unto you, a little while and ye will leave me; for it is written: I will strike the shepherd, and the lambs of his flock shall be scattered [Jn 16.32; Mt 26.31; Mk 14.27]. 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. For when we had eaten the Passover on the third day of the week at even, we went forth to the Mount of Olives; 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 ward with Pilate the night after the fifth day of the week. But when it drew on (towards day) on the Friday, [182]] they accused him much [Mk 15.3] 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. – But in the Gospel of Matthew it is thus written: At even on the sabbath, when the first day of the week drew on, came Mary Magdalene and the other Mary to see the tomb. And there was a great earthquake: for an angel of the Lord came down and rolled away the stone [Mt 28.1-2]. – And again (there was) the day of the Sabbath; and then three hours of the night after the Sabbath, wherein our Lord slept. And that was fulfilled which He said: The Son of man must pass three days and three nights in the heart of the earth [Mt 12.40], as it is written in the Gospel. And again it is written in David: Behold, thou hast set my days in measure [Ps 38.6 LXX]. Now because those days and nights came short, it was so written. [183]]
