✦Grammar Breakdown
Çacommenceàquelleheure?
Ça (demonstrative pronoun)
‘Ça’ is the informal contraction of ‘cela’, used like ‘it/that’ in everyday speech.
commence (present tense)
‘commence’ is the third‑person singular present of the verb *commencer* (to start).
à (preposition of time)
When asking about a point in time, French uses the preposition *à* before the time expression.
quelle heure (interrogative phrase)
‘Quelle’ agrees with the feminine noun *heure*; the whole phrase means ‘what time’. Never say *quel heure*.
question format
The sentence follows the common spoken pattern ‘Ça + verb + à quelle heure ?’, which is informal but perfectly natural.

✕Common Mistakes
Ça commence à quel heure ?
‘Heure’ is feminine; the correct interrogative adjective is *quelle*.
Ça commence quand ?
While understandable, *Quand ça commence ?* is less natural than the set phrase *à quelle heure* for precise time queries.
Commencer à quelle heure ?
The verb *commencer* does not need a preposition before the time expression; the correct order is *commence à quelle heure*.

Cultural Tip
In French, the standard way to ask for a time is *à quelle heure*. The informal *ça* makes the question sound friendly and conversational. In a formal setting (e.g., a business email) you’d replace *ça* with the specific noun: *Le séminaire commence à quelle heure ?* Also, remember that *heure* is feminine, so the interrogative adjective must be *quelle*, never *quel*.
