Compound Adjectives
When a number + noun is used as an adjective before another noun, hyphenate it. "A two-hour meeting." "A five-day course." "A ten-storey building." Notice the noun in the compound is singular even if the number is more than one: "a three-week holiday" (not "three-weeks"). When used after the noun as a predicate, no hyphen: "The meeting was two hours long."
