Hi kitty Kelly,
I think I have found the example in a Kwiq -
Il est arrivé le dernier jour de la semaine _____ ( He arrived the last day of last week)
should be dernière as the word it refers to is semaine which is feminine.
Hope this helps!

@Cécile: I am confused. Le dernier jour de la semaine seems correct to me because dernier refers to jour, right? You may be missing a dernière in your sentence.Le dernier jour de la semaine. -- The last day of the weekLe dernier jour de la dernière semaine. -- The last day of the last week.

Chris, you had to fill in the blank which is 'dernière' ...

Oh, I missed the underlining at the end as part of the sentence. Of course. It makes sense now. Sometimes things are just too obvious. :)))
