Best Answer

For one lunar day, it takes 29 days, 12 hours and 44 minutes, this is also the time taken for the moon to go through all phases and back to the same one again. Its slightly longer than the 27 days 7 hours and 43 minutes that the moon takes to orbit the Earth, as the moon has to travel a little further to get back to the same phase, since the Earth has progressed around the sun a little in that time (changing the angles).

It's 29 days, 12 hours and 44 minutes. Since the moon is tidally locked to the earth- where the same face always points to us on earth, the lunar day is about the same length as the time taken for it to orbit the earth, though a bit longer due to our planets movement with respect to the sun during that time.
