clear as day

Totally unmistakable now

Clear as day describes something obvious, unmistakable, or easily perceived: The evidence was clear as day.

The phrase compares visibility or comprehension to broad daylight, when everything is plainly visible.

It emphasizes certainty—something so apparent it cannot be missed or misunderstood: I saw him do it, clear as day.
