You say: medio pasado una hora
30 past, or before (the hour)
To express time up to the half hour, you typically state the hour and then the minutes past that hour. For example, if it's 2:15, you would say "It's fifteen minutes past two." If it's 2:30, you would say "It's half past two." For times before the half hour, you can use phrases like "It's ten minutes to three" for 2:50.
The Spanish word for half is media (sounds like may-dia). When used in telling the time to just say half hour one could say media hora. The literal translation to a spanish ear would be "half hour". It is more commonly used like this "dos y media" which means 2:30 or two and half. The word "a" (a half) is never used this way.
Son las diez y media.
"Half past" when referring to time is "y media" It is pronounced "ee MAY-dee-ah". It is used in this way: "It is half past 5". "Son las cinco y media". Please see this site for confirmation of the translation: http://www.answers.com/library/Translations
Half moon in Spanish is medialuna
"The hour" is "la hora".
Half an hour is 30 minutes.
To say, 'the cocktail hour', you say, "La hora del cóctel."
"Son las diez y media"
Half past in French is demie. If you wanted to say half past one in French you would say: Il est une heures et demie. It is one hour and half. Half past one. I have put the French way at the top, the complete translation in the middle and then the English way at the end.
