As the moon moves eastward around 13 to 15 degrees per day in the sky in its orbit about the earth (there are 360 degrees around the whole sky for it to complete its orbit in 27.3 days), it moves with respect to the background stars noticeably each day, causing it to rise nearly an hour later each day/night when compared to the previous day/night.
As with all directions we have to choose the labels arbitrarily: North did not have to be up on the map; and clocks could have been designed the other way around. The Moon orbits the Earth, and the rest of the planets also orbit the Sun, in this same direction. The direction arises from the initial angular momentum of the material that made up the Solar System.
