According to a dictionary throughout is used to indicate every part of a place or an object. I'm not sure how to use it when referring to a period of time. Are the following sentences correct:
1) He was standing there throughout the entire round.
2) I was out of the country throughout summer.
I posted this very question on another page and the answers were mixed. Some wrote that it should be 'through.'
It makes sense since we do say "I slept through the movie/my class."
