"Tuesday is a day of the week."
Translation:Marți este o zi a săptămânii.
Could please someone explain what is the role of 'a' in this sentence.
it said "Marți e o zi din săptămână" for the multiple choice options, so 'din' can be used instead of 'a' ?
Isn't zi and ziuă the same. Ziuă isn't accepted as a possible response.
