Explanation:
Detailed explanation-1: -You use ‘an’ before words that begin with the five vowels – a, e, i, o, u. However, the way you pronounce it and not the spelling, shows you which one you must use. Examples: You should say, ‘an hour’ (because hour begins with a vowel sound) and ‘a history’ (because history begins with a consonant sound).
Detailed explanation-2: -A half-hour is a period of 30 minutes.
