Because the Moon orbits the Earth about once each month. Since the moon is roughly spherical, when light hits it on one side we seen a different shape depending on its position relative to Earth, and these shapes define the different phases.
The percentage of the moon that is illuminated varies during different lunar phases. During a full moon, 100% of the moon is illuminated, while during a new moon, 0% is illuminated. The waxing and waning phases fall somewhere in between, with values from 1% to 99% illuminated.
If you watched Earth from the near side of the Moon for a month, you would see the Earth go through phases, similar to how we see the Moon's phases from Earth. You would observe the Earth's rotation, witnessing different continents during the day and night. Additionally, you would see the Earth's position change relative to the surrounding stars as it orbits the Sun.
Some people expect to see the Sun during the day, and the Moon in the darkness of the night. But, depending on the position the Moon has reached in its orbit round the World, the Moon may appear during the day. Once the Sun is shining brightly, the Moon is less, if not impossible to see, because of the brightness of the daylight. Early dawn or twilight, when the sky is not too bright is the best time to see that the Moon, in all its phases, can appear during the day.
The two motions that cause the Moon to show a complete cycle of phases each month are its orbit around the Earth and the Earth's rotation on its axis. As the Moon orbits the Earth, the angle between the Earth, Moon, and Sun changes, resulting in the various phases of the Moon. Simultaneously, the Earth's rotation allows us in New York State to observe these phases over the course of the month as the Moon rises and sets at different times. Together, these motions create the full lunar cycle we see each month.
Contrary to popular belief, the phases of the moon throughout a typical month have nothing at all to do with earth's shadow. The earth's shadow passes over the moon only at the time of full moon, and only rarely does it do that. The various phases of the moon that we observe come about because we are actually seeing the long lunar day (it is equal in length to the moon's phase cycle-- one synodic month) pass over the face of the moon that we can see from earth. It's odd to think of the moon going through a day, but as the moon orbits around earth it stands to reason that we will see the moon changing its relationship with the sun. Sometimes we will see the sun shining more on the face we can see, and sometimes we will see the sun shining on the moon at different angles.

the moon reflects the sun's light. you can only see some of this reflected light.
The phase of the moon that you see is the part of the moon that is illuminated by the sun. The relative positions of the sun and moon with respect to a viewer on Earth gradually shift during the lunar month, so that different sections of the moon are illuminated.
It takes a full month to see all phases of the moon, then it begins again.
The percentage of the moon that is illuminated varies during different lunar phases. During a full moon, 100% of the moon is illuminated, while during a new moon, 0% is illuminated. The waxing and waning phases fall somewhere in between, with values from 1% to 99% illuminated.
The amount of lighted side of the moon you can see is the same during first quarter and third quarter phases. These phases occur when half of the moon's surface is illuminated, and they represent the halfway points between new moon and full moon phases.
In October 2023, the moon phases transition from a New Moon to a Full Moon and back to a New Moon, reflecting the typical lunar cycle of approximately 29.5 days. The waxing phases occur in the first half of the month, leading to the Full Moon around mid-month, followed by the waning phases as it decreases back to the New Moon. This pattern illustrates the consistent rhythm of lunar visibility, impacting tides and cultural events.
The phase of the moon you see depends on how much of the sunlit side of the moon faces earth.
Sure. It takes you a month and there's no way to rush it, but if you're patient and the sky is clear, you can see all of them, from anywhere on earth.
