We have discussed Present Perfect versus Past Simple in "It has been on the news" vs. "it was on the news". Now I'm asking about Present Perfect versus Present Simple.
I know that the sentence in Present Perfect, "it has been a tough day", implies that the day is still going. But would it not be much easier to say "it is a tough day"? Because if a day is tough, you just say that the day is tough.
What does using Present Perfect add to the statement?
