Brought up earlier was the Apostolic Constitutions.

As I mentioned, this offers the Roman view and uses Roman timing; that is, Christ ate Passover at the end of the 14th and was crucified and then buried at the end of the 15th. And the 15th was Friday (preparation).
(4) And on the fifth day of the week [Thursday], when we had eaten the passover with Him, and when Judas had dipped his hand into the dish, and received the sop, and was gone out by night, the Lord said to us: "The hour is come that ye shall be dispersed, and shall leave me alone;" ... (12) in their madness cast upon Him, till it was very early in the morning, and then they lead Him away to Annas, who was father-in-law to Caiaphas; and when they had done the like things to Him there, it being the day of the preparation, they delivered Him to Pilate the Roman governor, accusing Him of many and great things, none of which they could prove.
That was written c380ad. Evidently books 1-6, from which the quote came, were based on the Didascalia Apostolorum, which was written about 200 years earlier.

The reason I bring this up is because of this:
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.
Chapter 21
In this didascalia view, there is a lag of a couple days between when Christ was arrested and when He was crucified. Whereas William has argued for the same thing, though at feast week end, the Pope in his new book had alluded also to a lag time (mentioned earlier in the thread) for the same three reasons; "not on the feast day" and not enough time for the trials and illegal to hold a trial on the feast sabbath (the 15th).
Tuesday-eat passover at the end.
Wed-arrested.
Thurs-trials/held
Fri-crucifixion.
I thought it interesting, but not convincing because of scripture and the quartodeciman tradition through Polycarp, Melito, Polycrates.
