The issue here is because the days of weeks are in blocks of weeks, there seems to be a confusion because of a Wednesday being placed into a future week, If we had a line of poles across 2 paddocks say 7 in each and you are standing at the first pole, the next pole is the second pole, not the second pole in the next paddock, same as if you are on Monday the next Wednesday is 2 days hence not Wednesday of next week. Similar to the earlier reference of next train, no other units of measurement places next as anything but the very next item, the options to clarify what seems to be an incorrect evolution of the term here is, next is next, a day in next week is a day of next week or as was known previously E.G. Wednesday week, meaning Wednesday of next week. or give the specific calendar date to avoid confusion.
