The question never occurred to me and I admit ignorance of most of the finer details surrounding the crucifixion. So I started looking at the question from the very basics. One answer leads to 3 more questions, which lead to a feast of information. Before long my head is filled with more information than it can sort out.
It seems much of the Roman Empire used an 8-day week (the nundinae) around the time of the crucifixion. The 7-day week wasn't really nailed down (no crucifixion pun intended) across the Roman empire until almost 300 years later. With the Romans controlling Jerusalem, did they impose an 8-day week on the land? Or were the Jews in charge of the calendar and observing a 7-day week? If both, would you state the day of the week as the officially recognized by the government, or use a religious calendar? To complicate things further, between the last century BC and maybe the 4th century AD, calendars everywhere were in a constant state of flux (no boolit casting pun intended). I'm not totally convinced there even was a Wednesday that year.
I don't envy scholars one little bit. The details are too intense. I agree with the sentiment that it's the events of the day, not the exact day of the week, that's important.
