It takes the moon 29.5 days to go through all phases, from full moon, back to full moon for example.
Relative to the background stars and ignoring the earth position relative to our sun, the moon takes 27 days 7 hours and 43 minutes to orbit the earth - the sidereal orbit. During this time, the earth has progressed around the sun a little, on its orbit around the sun. For the moon to get back to exactly the right phase, it takes a little longer, 29 days, 12 hours and 44 minutes in total from full moon to the next full moon.
