✕Common Mistakes
Hier, c'est quel jour ?
‘c’est’ is present tense; the sentence refers to the past, so you need the imperfect ‘c’était’.
Hier, quel jour était hier ?
Missing the ‘c’était’ makes the sentence sound incomplete; French prefers the ‘c’était + quel jour’ pattern.
Quel jour hier était‑c' ?
Incorrect word order and misplaced inversion; the natural order is ‘c’était quel jour hier’.
↔Alternatives
Quel jour était‑ce hier ?
Which day was it yesterday?
Hier, c'était quel jour de la semaine ?
Yesterday, what day of the week was it?
C'était quel jour hier ?
What day was it yesterday?
Cultural Tip
In French, days of the week are never capitalized, unlike in English. The construction ‘c'était + quel + noun’ is very common for asking about past facts. For a more formal tone you can invert the subject and verb: ‘Quel jour était‑ce hier ?’. In everyday speech, the simpler ‘C'était quel jour hier ?’ is also perfectly natural.
