This video will help you practise telling the time in Spanish:
Notes: AM/PM are often distinguished by saying de la mañana(morning), de la tarde (afternoon), de la noche(evening/night) or de la madrugada (late night).
Times are also often given in the 24 hr clock format (eg. 1pm is 1300):
1300 - las trece, 1400 - las catorce, 1500 - las quince etc. (see the section on Spanish numbers forfurther examples and pronounciation guides).
With the 24-hour clock, the words cuarto (quarter) and media (half) aren't used:
1315 las trece quince ('the thirteenfifteen' ie. 1.15 pm) 1630 las dieciseis treinta ('thesixteen thirty' ie. 4.30pm) 1745 las diecisiete cuarenta y cinco ('the seventeen fortyfive' ie. 5.45 pm)
