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

Pronunciation: eel eh trwah er eh duh-mee duh lah-preh-mee-dee

Meaning: It is half past three in the afternoon.

In French, use 'et demie' (with 'demie' agreeing in gender with 'heure'), but note that you only use 'et quart' and 'et demie' for quarter and half hours—for other minutes, use 'heures' without the 'et'.
