WELL it takes 29.53 days for it to be a fully full Moon.
Edit: the answer to the question is:- When the Earth is between the Moon
and the Sun we see the whole of the illuminated (by the Sun) part of the Moon.
(Unless the line-up is perfect, and we get an eclipse of the Moon.)
It is a shodow from the earth.

It's the earth shadow
The moon must be on the opposite side of the Earth from the Sun to appear full. This alignment causes the sunlight to fully illuminate the side of the moon facing the Earth, creating the appearance of a full moon.
Spring tides happen during full moon and new moon. The additional gravitational force of the sun, causes the tides to be higher (springs).
During a full moon, the Earth is positioned between the Sun and the Moon. The Sun is illuminating the side of the Moon that faces Earth, making it appear fully lit from our perspective. This alignment causes the Moon to appear bright and full in the night sky.
Solar eclipses are caused by the Moon covering the Sun. This can happen at new moon. Lunar eclipses are caused when the Moon gets into Earth's shadow. This can happen at full moon.
When the moon is full, it's "behind" the earth, that is, in the direction opposite the sun. The three bodies are lined up, with the earth in the middle, like this: Sun ---------------------------------------------------------------------------Earth -- Moon
A full cycle - e.g., from full moon to full moon - is about 29 1/2 days. From new moon to full moon is half that time.A full cycle - e.g., from full moon to full moon - is about 29 1/2 days.

The shadow is caused by the earth blocking the path of the light from the sun casting shadow on the moon. When the earth is not in between the sun and the moon then we have a "full moon."
During a full moon when Earth passes between the Moon and the Sun, a lunar eclipse can occur. In this event, the Earth blocks the Sun's light from reaching the Moon, casting a shadow on the Moon. This causes the Moon to appear darker and take on a reddish hue, known as a "blood moon."
