The Moon makes a complete orbit around the Earth with respect to the fixed stars (its sidereal period) about once every 27.3 days. However, since the Earth is moving in its orbit about the Sun at the same time, it takes slightly longer for the Moon to show its same phase to Earth, which is about 29.5 days (its synodic period).[8] Unlike most satellites of other planets, the Moon orbits near the ecliptic and not the Earth's equatorial plane. It is the largest moon in the solar system relative to the size of its planet. (Charon is larger relative to the dwarf planet Pluto.) The natural satellites orbiting other planets are called "moons", after Earth's Moon.

Most of the tidal effects seen on the Earth are caused by the Moon's gravitational pull, with the Sun making only a small contribution. Tidal effects result in an increase of the mean Earth-Moon distance of about 3.8 m per century, or 3.8 cm per year.[48] As a result of the conservation of angular momentum, the increasing semimajor axis of the Moon is accompanied by a gradual slowing of the Earth's rotation by about 0.002 seconds per day per century.[49]

Even though I am sure most of you are giving information the questioner intended to get, his question is very poorly worded.
The correct answer to the question that was actually asked is:
Zero.
The moon ORBITS around the Earth and has probably done so about 52 billion times since its formation by global impact.

The Moon REVOLVES about its own axis. I cannot give you an estimate, I know the Earth was revolving about 5 times faster than now shortly after global impact, but do not have a figure for the Moon.

Magnetism has nothing to do with planets and moons orbiting - gravity is completely different. And the moon "revolves itself":it just happens to do it at the same rate as it goes round the earth, so we see the same side all the time. If a mother is holding hands with a child and dancing swinging the child around from the mother's view, the child is always facing and may not seem to be going around, but any one else looking at the pair can see that obviously the child is going around facing different parts of the room while also facing the mother. You have so little correct knowledge that it is difficult to give an "exact reason" and trust you will understand it.

The time it takes the Moon to orbit the Earth is called a month.

In relation to "fixed stars", the average sidereal month is 27.321662 days (days defined as 86,400 seconds); when calculating orbital mechanics (such as orbital inertia and momentum), this is considered the "real" orbital period.

In relation to the Sun and, therefore, to Moon phases (e.g., from New Moon to the next New Moon) the average synodic month is 29.530589 days; when determining dates according to lunar calendars (e.g., muslim calendar) or soli-lunar calendars (e.g., Chinese), this is the month to use.

For astronomers, there are other types of months, such as "anomalistic", which is the average time from perigee to perigee (perigee is the closest point to Earth, on the Moon's orbit -- the furthest point being called apogee); the anomalistic month is used in predictions of tide heights.

Because of Earth's spin (once per 'day') and the Moon's orbital speed, the Moon crosses a fixed observer's meridian a little later every day. This period is called a 'lunar day'; it has an average of 24h48m46s and it is used in prediction of tide times.

Because this name (lunar day) has been around for a while, one has to choose words carefully when describing 'a day on the Moon' (time from sunrise to the next sunrise for an observer on the Moon = same as synodic month).

During a period called 'exeligmos' (or three Saros cycles), of 19,756 Earth-days, the Moon will have had exactly 669 synodic months (orbits relative to the Sun) and almost exactly 723 sidereal months (orbits relative to the stars).

It's revolved around the Earth many millions (or billions) of times so far.

every 28 days or 13 times a year and its called a Lunar Cycle.
