2.7.2 Vingt-quatre heures
The 24-hour clock is commonly used in France for timetables (for example train timetables, television programmes, opening times).
It is expressed like this: 13 h 15. The letter ‘h’ stands for heure(s). To say it you simply read the numbers as they appear: treize heures quinze. N.B. You will need to make a liaison between the first number and heure(s).
Where the numbers end in a consonant, you make a liaison between the consonant and heures. Where numbers end in ‘e’ the ‘e’ is silent and so you make a liaison between the final consonant and heures.
