One full revolution of that planet. The planetary day of Earth is 24 Earth hours long. Other planets spin at various speeds, with Jupiter the fastest (shortest day) and Venus the longest (barely rotating, and in the opposite direction of its orbit).
Because of the short year on Mercury (88 Earth days), and its long day (59 Earth days), the apparent "solar day" on its surface is twice its year, or 176 Earth Days.
