Telling the time in French
One important thing to note when talking about the time is that the French make greater use of the 24 hour clock than we typically do. You'll frequently encounter it in more formal situations (for instance, when making appointments) and also when clarifying whether a time is in the morning or in the evening.
In casual conversation where it's pretty obvious whether you're talking about day or night (for instance, when you're talking about going for dinner at eight'o'clock) it's more common to use the 12-hour clock.
In writing, you'll never see times written as 5pm or 3am. It will always be written 17h30 (5:30pm) or 22h (10pm).
To say the time, use il est followed by a number and then heure(s)
To say something like ten to eleven or quarter to five you should use moins (minus/less)
(literally: It is eleven hours minus ten)
(literally: It is five hours minus quarter)
To say something like it's ten PAST eleven simply put the number of minutes after the hour.
Add an et when saying quarter past or half past
