Go back and read your scriptures. The events from Friday until early on Sunday are described along with the passage of the days and nights. There are no events for the extra days that you have advocated. Nor are the passage of these extra days and nights described in the scripture. There is no evidence that there were two Sabbaths from the text. What you have given is nothing more than conjecture to give you an excuse to stick the boot into the established Christian religion. Your stark literal demand for 3 entire days and 3 entire nights might find a certain appeal amongst the simple minded who could thereby be lured away from the mainline christian churches into quasi-Christian sects and cults but if you think that anybody with any background with the scriptures and the history of the Christian church is going to buy in then you are sadly mistaken.
We know with certainty that the 1st Day of Unleavened bread was on the same day as the Sabbath that year making it both a Sabbath and a High Day. Any of the seven Jewish Feast days were High Sabbaths.
We do not need to consult ancient calendars and make astronomical observations or peer into the history pages of records of eclipses or anything like that to know that the Sabbath was on the 1st Day of Unleavened Bread because THE SCRIPTURE TELLS US IT WAS. "John 19:31 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,)
So lets read the account with this clearly fixed in our mind that the sabbath was a High Day

Luke 23:52 This man went unto Pilate, and begged the body of Jesus. 53 And he took it down, and wrapped it in linen, and laid it in a sepulchre that was hewn in stone, wherein never man before was laid. 54 And that day was the preparation, and the sabbath drew on. 55 And the women also, which came with him from Galilee, followed after, and beheld the sepulchre, and how his body was laid. 56 And they returned, and prepared spices and ointments; and rested the sabbath day according to the commandment.
Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them. 2 And they found the stone rolled away from the sepulchre.
No problem. Where is the extra sabbath, where are the extra days. The simple reading of this account is unequivocable, that Christ was buried on Friday the preparation day for the sabbath. The women rested on the sabbath and came early the next day (sunday). Even a child can understand this simple account. Only individuals with powerful ulterior motive could be led to twist and distort this simple account to fabricate a wednesday burial and sat evening resurrection (or any other bizarre combination).
If we lived in a different age this new fangled modern teaching that is an innovation of the last century would be declared as a heresy and its teachers cast out as anathema. The danger to men's souls of this teaching that Christ was dead for an entire three days and three nights is incalculable as it serves as a hook into a range of other associated sabbatarian teachings of the judaisers. Let us all be warned.
