Luna, Earth's Moon takes one month to turn once on its axis. That is why we use the word, "Month" (from the very old word, "Moonth") to describe that period of time.
The moon spins once on its axis every month; one sidereal period around earth is equal to one complete rotation on its axis. If the moon did not rotate, all of its surface would be visible from earth over the course of a month.
Earth's moon does rotate on it's axis but it does it once each orbit of the Earth: every 27.3 days .
