I'm trying to gain the full understanding of perfect tenses. Are my explanations about the sentence and the difference between using the Present Perfect instead of the Simple Past correct?
It has been a tough day. [As opposed to "It was a tough day."]
This day still continues and new tough things may happen.
It has been on the news. [As opposed to "It was on the news."]
The story (that is on the news) is still developing; new facts may appear, and the whole thing is not yet over.
