10h (time expression)

✕Common Mistakes
Ça ouvre à 10h tous les jour.
“Jour” must stay plural because it’s modified by “tous”.
Ça à 10h tous les jours.
Missing the verb “ouvre”. The sentence needs a verb to be complete.
Ça ouvre à dix heures tous les jours.
While grammatically correct, saying “dix heures” is more formal; in casual speech you’d keep the short “10h”.

Cultural Tip
In France many small shops close on Sundays, so saying “tous les jours” often implies a larger venue (museum, train station, chain store) that really does open daily. Also, French uses the 24‑hour clock in most written contexts, so you’ll see “10h00” on timetables. The informal “ça” is perfect for conversation, but on official signs you’ll find “Ouvert de 10h à 18h”.
