It is called synchronous rotation when the rotation and orbit take the same amount of time.
The rotation of a planet refers to the planet spinning like a top; a "revolution" is the time required for the planet's orbit around the Sun.
The period of rotation for each of the planets is as follows - the sidereal rotation (rotation time against background stars); PlanetSidereal rotational periodMercury58.646225Venus-243.0187Earth0.99726957Mars1.02595675Jupiter0.41007Saturn0.426Uranus-0.71833Neptune0.67125
