Making no secrets or attempts to hide something. For Example: If you do something in broad daylight, you’re doing it for anyone to see.

Too far along in a certain activity to attempt a certain action. For Example: “Jim thought we should kick a field goal, but it was too late in the day for that. Since we were down by 21, we had to try to go for a touchdown.”

To declare the end of a day’s work. For Example: “Alright, I think we got enough orders shipped out today. Let’s call it a day and go get a beer.”

A wild guess. For Example: “The final question was ‘who won the World Cup in 1994?’ I didn’t have any clue, so I just took a shot in the dark and said Spain.”

Ignorant of a certain fact or issue. For Example: “In the debate when the Senator was asked his opinion on nuclear waste disposal, it was clear by his stuttering that he is in the dark on that issue.”
