Do you mean that if you take the ticket lets say wednesday, then its only valid til sunday, therefore making it not really a weekly pass but a 5 day pass...?
I can only repeat (for the fourth time in this thread) what I have said before: the only option for a weekly pass is Monday through Sunday. No matter on what day you "take the ticket", it is only valid until the end of Sunday. Please refer all further inquiries to the STM site (you can find links in my post # 6), I am done with this topic.
In any case we obviously have very different way of speaking
Understatement of the week.
