- The phrasesa half, half of, and half a or half an are all correct, though they may differ slightly in meaning.For example,a half day is used when day has the special sense "a working day,” and the phrase then means "4 hours.” Half of a day and half a day are not restricted in this way and can mean either 4 or 12 hours.短语a half，half of 和 half a 或者 half an 都是正确的， 尽管它们可能在意义上稍有不同。例如当day 当工作日来讲时， a half day 这个短语的意思是“四个小时”。 Half of a day 和 half a day 的意思不限于此， 它们可以表示四小时或者十二小时
