An entire cycle is about 29 1/2 days, on average. The "phases" are more like points in time, when the Moon shows a certain shape.
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
The NASA web site has a table of phases of the Moon at http://www.usno.navy.mil/USNO/astronomical-applications/data-services/phases-moon It doesn't matter where YOU are for the phases of the Moon; this table is the same for everyone.
It takes about 29.5 days for the moon to go through all its phases and return to the same phase again, known as a lunar cycle or lunar month.
As long as the observer is some place on the earth, his locationhas essentially no effect on the moon phase that he sees.

About 29 days
The moon spends approximately 7 days in each of its primary phases: new moon, first quarter, full moon, and last quarter. The exact duration can vary slightly because of the moon's elliptical orbit around Earth.
