Come on, let’s call it a day.
Let’s finish. who we say, call it a day mean they’ve been working from 8 o’clock. 6 o’clock now. You have not finished the work. But everybody is tired. So tomorrow is another day. Let’s call it a day. It only means it, doesn't mean you finished, but just mean we had enough. That is enough for one day. Let’s call it a day. Enough is enough. We are tired. It is very hot. Tomorrow is another day.
- So still nothing finished, but...
Yeah, it’s very common use, though. It’s very, very common. Let’s finish! Let’s stop! What you are saying is “you had enough? “yeah, I am tired” “me, too” “let’s finish! Tomorrow is another day.” But it doesn't mean, “For thank goodness. we’ve finished. now we can go home.” You wouldn't say “let’s call it a day”. “Call it a day” is something that is continuing on, not finished yet.
