The correct answer is: Yesterday, Today, and Tomorrow.
These are three days in a row—they happen consecutively in real time—without ever mentioning any weekday. The riddle works because it doesn’t require calendar labels; it only asks for consecutive days, and “yesterday → today → tomorrow” is a continuous sequence everyone understands.
Why it fools so many people: our brains automatically jump to the seven-day calendar system, but the wording leaves a loophole. Once you notice that, the solution becomes straightforward: you can describe days by their position relative to the present instead of by their names.
