When it's time to wrap things up and call it a day, there are plenty of synonyms to convey that message. You might say it's time to close up shop, pack it in, or shut things down. Other options include winding down, finishing up, or bringing things to a close. If you're ready to head home, you might say it's time to hit the road, call it quits, or cut out. Or perhaps you prefer to use the phrase "time to hang up my hat," "throw in the towel," or "retire to bed." No matter how you choose to say it, there are plenty of ways to let others know that it's time to call it a day.
