The complete cycle of the moon's 'phases' ... the time to go from any shape
to the next appearance of the same shape ... averages 29.531 days.
29.531 days (rounded)
I learned this in science class- it takes 29 1/2 days for the moon to go from new moon to the next new moon.
this depends on what you mean. for the moon to return from one phase to the same (for example new to new or full to full) it takes 29.53059 days (29 days, 12 hours, 44 minutes and 3 seconds). this accounts for the rotation of the earth. so for all intents and purposes as viewed from the earth's surface- this is the best answer. if you watch and measure from anywhere on earth, this is the duration of one lunar orbit. the most exact answer for the question as i interpret it is on average 27.21222 days- this is the nodal month, which is the duration the mood takes to travel from one node of its orbit to the same node. this does not take into account the rotation of the earth. this is 'one complete trip' as viewed from anywhere outside the earth and is more accurate for this question as i interpret it.
It takes 29.531 days. (rounded) That's the time required for the moon to physically orbit the Earth (27.32 days), plus the extra part of the orbit that it has to cover to make up for the roughly 27 degrees that the Earth has moved in its orbit during that time ... since the visual 'phases' are all the result of our positions compared to the sun.
That's called the "Third Quarter" phase. It occurs about 22 days after the New Moon.

The phase in which the moon is not visible from earth is called the "new" moon. It happens when the moon is aligned between the sun and the earth (every 28 days), which causes the side of the moon that we usually see to be in shadow.

It takes our moon about 27.3216 average earth days to complete an orbit of the Earth. However, due to the Earth's progress in its orbit of the sun during that time, it takes an additional 2.2 days to get to the same phase, or position with respect to the sun, as when the orbit started.
It takes Pluto 248 years to orbit the Sun. That means that one year on Pluto is 90,520 Earth days.
