IF you can count, and given in our modern era, Sunday, is the 'first' day of the week, and Christ was NOT in the tomb when the 'sun' rose, it is NOT misleading to say the Bible's time-line would make it our named day Wednesday the 'day' of the Crucifixion. More than one place it is Written that Christ would be in the tomb 3 days and 3 nights. It is not even possible to get anywhere near this time frame IF the Crucifixion took place on what some claim happened on Friday.
The Scriptures nowhere mention Wednesday.
If our indicator is the first day of the week, Scripture tells us numerous times that Jesus would be raised on the third day. If He was raised on Sunday then Sunday is the third day, Saturday is the second day and Friday is the first day.
I would also point out that if Jesus were buried for three entire days and nights then he would have been raised on the fourth day, not the third.
I will go with the nine times Scripture tells us about the third day as opposed to the one time In the New Testament a reference is made to three days and three nights - i.e. Implying a resurrection on the fourth day.
And, if we take your methodology to the extreme and get supertechnical, it would even be a fifth day, since presumably the crucifixion, indubitably a daytime event, would have taken place on an initial day, followed by three complete days and nights - days 2, 3 and 4 - followed by a resurrection after those three days and nights had been completed, or on day 5.
