How to tell time in French?

French use both 12 hours clock and 24 hours clock. Though 24 hours clock is official, we use 12 hours clock with "du matin" for am and "de l'après-midi" for pm (afternoon) and "du soir " for pm (evening).
un quart = a quater, demie = half, trois quarts= three quarters.
Learn and practice. Bon courage !
