let's call it a day
Let's finish working for the day. A: "We've been staring at these spreadsheets for hours now, and we still haven't found the source of the discrepancy." B: "Let's just call it a day and come at it with fresh eyes tomorrow." Put this package in the mail for me, and then let's call it a day.
Let's call it a day.
Fig. Let us end what we are doing for the day. Mary: Well, that's the end of the reports. Nothing else to do. Sue: Let's call it a day. Bob: Let's call it a day. I'm tired. Tom: Me too. Let's get out of here.
