Il est trois heures et quart de l'après-midi.

Pronunciation: eel eh trwah zeur eh kar duh lah-preh-mee-dee

Meaning: It is 3:15 in the afternoon.

In French, use 'et quart' (and quarter) for :15 and 'et demie' (and half) for :30, but avoid these expressions for other minutes—just say the number instead.
