Will passer take avoir in past with indefinite article

Question

Je____(passer)(passé composé) un mois à Rouen.Will we consider it direct object and will auxillary change to avoir

Accepted Answer

Bonjour Maira,
The use of the auxiliaries 'avoir' and 'être' doesn't have anything to do with the indefinite article - see link here: passer-can-be-used-with-avoir-or-etre-in-le-passe-compose

J'ai passé un examen =I passed an exam 
J'ai passé un mois à Rouen = I spent a month in Rouen
Je suis passé par chez toi = I went by your place
Je suis passé par la pharmacie = I popped by the pharmacy

I looked at your profile and I can see that you have not taken the sorter test yet. This will make it easier for our Kwizbot to assess your level and to create a targeted studyplan.
I hope this is helpful.
Bonne journée !
