It depends which planet you mean - the Earth takes 23 hours & 56 minutes to rotate once.
URANUS TAKES EIGHTY FOUR DAYS TO ROTATE
it takes 365 days for the earth to go around the sun once.
Moon takes 27 days to rotate earth for one cycle.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
It takes Mercury about 88 Earth days, Venus about 225 Earth days, Earth about 365 days, Mars about 687 Earth days, Jupiter about 4,333 Earth days, Saturn about 10,759 Earth days, Uranus about 30,687 Earth days, and Neptune about 60,190 Earth days to orbit the sun.

Mercury.
The question is inconsistent. Rotation is the period a planet or moon rotates about its own axis. Revolution is the period a planet or moon revolves about its parent planet or sun. Mercury takes 88 Earth days to revolve about the Sun. It takes 59 Earth days to rotate about its own axis.
Moon moves around the planet Earth in an orbit and rotates on its own axis. It takes moon around 28 days to move around the planet Earth. Normally, the moon takes around 27 days to rotate on its axis.
Mercury takes 59 earth days to make one full rotation around its axis.
