Possibly, if it helps the reader understand the context. If we understand the Shabbat to fall on Friday/Saturday (rightly or wrongly) then we can talk about Wednesday, or whatever, in relation to Saturday, rather than using a somewhat-awkward and verbose construction like, "the third day before Shabbat". That could actually lead to more confusion, as we don't readily understand the scriptural method (or cultural method of that time) of referencing days.
For example, when Jesus is responding regarding Herod, he says, “Go and tell that fox, ‘Behold, I cast out demons and perform cures today and tomorrow, and the third
day I reach My goal.’ There is an implied reference to his death and resurrection, but it would be "two days from today" rather than "three days from today" the way we read His words. Yet when He is referring to Jonah, He says, "for just as Jonah was three days and three nights in the belly of the sea monster, so will the Son of Man be three days and three nights in the heart of the earth." Only if the first instance took place in the evening could those be reconciled; Scripture doesn't tell us that part.
If Jesus had said, "I will be crucified on a 'Naphtali-day' and rise again to life on a 'Reuben-day', we might understand a little better what He meant. That He didn't use (or inspire) names for weekdays, doesn't mean we shouldn't; it only means there is no biblical standard for us to use, so we use the one in our culture.
Japan attacked Pearl Harbour on December 7, 1941. The date means a lot to Americans and historians because of that attack and the war that followed. What some don't know is that it was a Sunday morning, partly chosen by the Japanese as a time when the American people would be relaxed and looking forward to a peaceful day. The date lives 'in infamy' but the day of the week was, at the time, more important. Even so, the name given to the day is irrelevant, other than as a cultural standard.
I suggest that where the Scripture is silent, we don't make an issue of it. Where the Holy Spirit convicts us personally, then we are to follow His leading.
