Cultural Tip
In very formal contexts French speakers prefer the structure *Quand est‑ce que…* or *À quelle heure…*. The short *Ça commence quand ?* is typical in spoken French, especially among younger people. Remember that “ça” can refer to anything that has just been mentioned, so make sure the listener knows the referent.
