If you buy it on a Tuesday or Wednesday, then you only get 6 or 5 days

IIRC, the monthly is similar, i.e. it runs on the calendar month, and
you can buy the current month up to 23rd (21st?) of the month.

The point is that you can buy it part-way through its validity, as long
as you accept that you won't get a full week's use out of it.

What a quite amazingly silly setup.

Surely it would be in RATP's interest to allow it to run for any
7-day/calendar month period? Otherwise they're just creating problems
in the form of massive queues at ticket offices on Mondays and the last
few days of each month?

Or do they do what Hamburg do and only open ticket offices on a small
number of days at all, thus saving on staff costs? (I think this
rotates around, though, so the same staff can cover different stations)
