Let's call it a day and have a drink.

Why don't we call it a day?

I am feeling a bit tire, I think I'll call it a day.

1) Let's call it a day and have a drink. 2) I'm getting a bit tired now - let's call it a day. 3) After 14 years living and working in this country, she thinks it's time to call it a day.

it is time to call it a day

To stop working, either at one's job or on a particular task, for the rest of the day. When we still couldn't find the source of the discrepancy, we decided to call it a day and revisit it tomorrow.

Let's call it a day unless you have any questions.

I'm too exhausted to finish it. Can we call it a day?
