The moon orbits the earth in a little under 28 earth days. It travels at almost 2,290 miles per hour. Coincidentally, the moon's rotation period is also a little under 28 days, meaning the same face points toward the earth during its entire orbit.
It takes the moon about 27.3 days to orbit the earth, and lunations, i.e. full lunar phase cycles, i.e. how we see the moon from earth depending on where it is in orbit, are only about 29.5 days, Gregorian months, with the notable exception of February, are 30 and 31 days, so if there's a full moon super early in a month there's a good chance we'll get a second one before the month's end.
