Hi Spinnaker, I think you wanted to write Let's call it a day! It means ''let's end the day'' or '' let us end (whatever we are doing) for today. '' Similar expressions include: 'Let's call it off for today' or 'time to hit the sack' though I reckon the second expression is mainly used to go to sleep.
