it is always rotating but sometimes you can't see it lololololo,ololololoololol
There are three different "Earth days". I will point you to a couple of links that have information about "Earth days", and lunar orbit information. Roughly, the Moon completes one orbit in 28 days, so it completes 1/28th of its orbit.
The Moon actually orbits the Earth, which it does in 28 days, but if you consider the Earth and the Moon as a double system, then the Moon orbits the Sun once a year, just as the Earth does. The Moon is much closer to the Earth than the Earth and the Moon are to the Sun.
About twenty-eight days.Answer:There are a lot of ways of looking at this depending on your relation to the Earth/moon system:The Moon's orbital period in a non-rotating frame of reference is 27.32 days (27 days, 7 hours, 43 minutes, 11.6 seconds). This is the sidereal month. It is measured by observing how long it takes the Moon to pass a fixed star.A synodic month is 29.53 days (29 days, 12 hours, 44 minutes, 2.8 seconds) It is measured from New Moon to New Moon. This is the most common way of expressing the lunar cycle.An anomalistic month is the Moon's orbital period measured from perigee to perigee - the point in the Moon's orbit when it is closest to Earth. An anomalistic month is about 27.55 dayson average.The tropical month is the time for the Moon to return to the same ecliptic longitude, i.e. measured from the equinox; it is slightly shorter than the sidereal month because of precession of the equinoxes.The draconic month or nodal month is the period in which the Moon returns to the same node of its orbit (one of the two points where the Moon's orbit crosses the plane of the Earth's orbit). Its duration is about 27.21 days on average.
No. A satellite in geostationary orbit remains stationary over a single point on the earth's equator. It must have an altitude of 22,236 miles above the earth, which makes its orbital period exactly one day. The moon is much too far away for that; its orbital period is 28 earth days.
Because the moon is much, much closer to the earth, so the earths immediate gravity has more of an effect on the moon. But the moon-earth "package" together both orbit the sun.

The Moon orbits the Earth, and tags along after the Earth. It takes one year - 365.25 days - for the Earth to orbit the Sun once, so that's the number for the Moon as well.
27.7 days
* 2,358,720 seconds * 39,312 minutes * 655.2 hours * 0.0748 years * the average time for the Moon to Orbit the Earth

First off the moon doesn't orbit around the earth. But it takes aproximatly one month to go through all the moon phases.
The combination of the Earth and Moon orbits the sun. That is, their common center of mass orbits the sun. Their common center of mass is the place where the pivot would have to be if the Earth and the Moon were on opposite ends of a see-saw. At the same time, both the Earth and the Moon are orbiting their common center of mass ... which is actually located inside the Earth, because the Earth has about 80 times as much mass as the moon has. Viewed by an observer on the sun, the Earth is in an elliptical orbit around the sun with tiny, almost imperceptible wiggles in it, and the Moon is also in an elliptical orbit around the sun, with much larger wiggles in it. The wiggles in both orbits repeat with a period of 27.32 Earth-days.
Because the moon is much, much closer to the earth, so the earths immediate gravity has more of an effect on the moon. But the moon-earth "package" together both orbit the sun.
The position of the earth and moon on their orbit around the sun, determines how much and what area of the moon is lit by sunlight. The moon's phases are what we can view from the earth.
