What is the main difference between a new moon and a full moon?

By Tom Kenneth Beck, On 14th March 2021, Under Science and Education
The difference is simply a matter of the moon's position in it's orbit around the earth relative to the sun. When it is between us and the sun we cannot see its lit side, and call it a new moon. When the earth is between the moon and the sun the moon's side facing us is fully illuminated and we call it full.

In this regard, what is the difference between a full moon and new moon after how many days a full moon changes into a new moon?

When Moon is in between Sun and Earth 100% of the side wee see is dark with out Sun light. WE call it new Moon. Changes take place from new Moon to full Moon in 14.5 days. full lunar cyscle from new Moon to new Moon is 29.5 days.

Likewise, what does the new moon mean?

In astronomy, a new moon marks the first lunar phase. As a new moon represents the start of a new lunar cycle, it symbolises new beginnings. People use the energy of a new moon to achieve their goals or start on a new project. They also reflect on their old goals and set themselves new ones.

How does a new moon affect you?

During this time, the new moon controls our mind and emotions, and makes us mimic its behaviour. Like the absence of the Sun's light reflecting off the new moon, our awareness becomes easily darkened and hidden from view – especially around emotional and primal matters.

Does a full moon bring good luck?

For some, a full moon is considered bad luck similar to walking under a ladder or breaking a mirror. However, in some instances, it is also thought to bring a bit of good luck, according to lunar lore.
The full moon has been associated with strange or insane behavior, including suicide, sleepwalking and violence. The lunar theory, otherwise known as the lunar effect, is the idea that there's some correlation between moon cycles and human behavior.
Moon. The moon is a feminine symbol, universally representing the rhythm of time as it embodies the cycle. The phases of the moon symbolize immortality and eternity, enlightenment or the dar k side of Nature herself.
A full Moon occurs when the Moon has moved in its orbit so that Earth is “between” the Moon and the Sun. Between the new and full Moon, the amount of Moon we see grows — or waxes from its right side toward its left side.
At new moon, the Moon is lined up between the Earth and the Sun. We see the side of the Moon that is not being lit by the Sun (in other words, we see no Moon at all, because the brightness of the Sun outshines the dim Moon!) When half of the Moon's disc is illuminated, we call it the first quarter moon.
Usually, new moons occur only once a month, but because there's a slight disjunct between the moon's phases—a 29.5-day cycle, on average—and the Gregorian calendar, some months can have two new moons: one at the beginning and one at the end.

These are the banana-shaped crescent Moon, the D-shaped quarter Moon and the almost complete gibbous Moon. Finally, each phase is also named after its position in the full 29.5 day cycle based on whether it is growing (waxing) or shrinking (waning).
At Full Moon, the entire face of the Moon is illuminated by the Sun's rays and it can be bright enough to light up otherwise dark nights. Technically, this primary Moon phase only lasts a moment, the instant when the Sun and the Moon are aligned on opposite sides of Earth (see illustration).
New moon is the day when you don't see the moon ( ideally moon is still there but since there is no light on that face, we could not see it) and sun is on other end. So full moon happens during night. So solar eclipse happens during day and lunar eclipse happens during night.
Biblical references use the moon symbol to highlight cosmic events, divine epiphanies and the ephemeral nature of human life and history (see, for example, Isaiah 30,26; 60,19; Revelations 21,23).
The Moon doesn't emit (give off) light itself, the 'moonlight' we see is actually the Sun's light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.
