How do you say the following in French?
a) I spent a day with Martin.
b) I spent the day with Martin.
My guess is:
a) J’ai passé un jour avec Martin. (following the example of "spent a year" indirectly)
b) J’ai passé la journée avec Martin. (following the quiz answer directly)
Am I correct? If so, why are the two different? Can I just remember "a" vs. "the" means one is a unit of time and one is emphasizing the duration? Thank you.
