Known as "First Quarter". The moon appears half-illuminated. If you are in the Northern Hemisphere, it is the half you see to your RIGHT. The moon rises in the east at roughly Noon, and sets in the west at roughly Midnight.
Approximately one week after the new moon phase, the waxing crescent moon phase occurs. This phase is characterised by a small sliver of the moon becoming visible on the right side.
One week after the full moon, the moon is in its third quarter phase. During this phase, the left half of the moon appears illuminated when viewed from the Northern Hemisphere, while the right half appears illuminated from the Southern Hemisphere. This is because the sunlight is shining on the opposite side of the moon compared to the full moon phase.
It takes approximately 29.5 days for the moon to go from one full moon phase to the next when viewed from Earth. This period is known as a lunar month or synodic month.
The complete cycle of the moon's 'phases' ... the time to go from any shapeto the next appearance of the same shape ... averages 29.531 days.
There are two phases of the moon that appear to be a half disk: the first quarter and the third quarter. The entire cycle of moon phases takes about 28 days (27.3217 days). Counting the day of a new moon as the first day, then the phases in order are: • waxing crescent • first quarter (a half lit moon resembling the letter "D") at end of week one • waxing gibbous • full at end of week two • waning gibbous • third quarter (a half lit moon resembling the letter "C") at end of week three • waning crescent • and back to the new moon, completing the cycle after week four
Approximately one week after the new moon phase, the waxing crescent moon phase occurs. This phase is characterised by a small sliver of the moon becoming visible on the right side.
One week from now, the moon will likely be in the first quarter phase, where half of the moon is illuminated. The new moon phase is followed by the waxing crescent phase and then the first quarter phase in the lunar cycle.
One week after the full moon, the moon is in its third quarter phase. During this phase, the left half of the moon appears illuminated when viewed from the Northern Hemisphere, while the right half appears illuminated from the Southern Hemisphere. This is because the sunlight is shining on the opposite side of the moon compared to the full moon phase.
One week after September 12, 2013, the moon phase visible from Earth on September 19, 2013, was the Waxing Gibbous. This phase occurs when the moon is more than half illuminated but not yet full, typically occurring between the First Quarter and Full Moon phases.
After the waxing crescent phase, the Moon enters the first quarter phase. During this phase, half of the Moon's surface is illuminated as seen from Earth, and it appears as a half-circle. The first quarter occurs roughly one week after the new moon, as the Moon continues to wax towards the full moon phase.
Full moon
Approximately two to three.... and they depend on the theoretical "starting point" phase. It takes about two weeks for the moon to go from "new" to "full". So, in one week the moon could go from "first quarter" to "waxing gibbous" to "full"

It takes about 29.5 days for the moon to complete one full phase cycle, from new moon to full moon and back to new moon again.
