Is it possible to say,"Hoelang zijn weken?"?
Yes, Duolingo also accepts "Hoelang zijn weken?" (2017-08-02)
7 days, weekend is too short
Can a Dutchie confirm that "hoelang" is one word - I have always had it as "hoe lang".
Thanks, very clear!
Why not duurt instead of zijn?
Duren, you need the plural because of weeks/weken
