The moon is visible all over the world (not just the Western hemisphere). In a 24 hour period the moon will be above the horizon for 12 of those hours. Depending on where the moon is in it's orbit relative to the sun determines when it is visible in the day.
New moon is when the moon is nearest the sun, and full moon is when it is furthest away. That is why a full moon is really only visible at night.
First quarterr moon rises about noon and sets about midnight. Last quarte moon rises about midnight and sets around noon.
The moon is brighter than the sky at daytime and so it is visible even against the blue sky of a sunny day.

The moon is bright enough and large enough that whenever it is in the daytime sky (but not too close to the sun) it will be visible during the day unless clouds or dust obscure it.
The moon will be visible for at least part of the daytime except when it is completely full which is when it is directly opposite from the sun. For one or two days before and after the new moon most of its sunlit side is away from the earth and it is so close to the sun in the sky that it washed out by the brightness of the sun. When the moon is new none of its sunlit side is visible but we might see it in silhouette against the sun during a solar eclipse.

The Moon is not *always* visible! It rises in the east and sets in the west just like the Sun does. But the time it rises and sets varies with the phase of the Moon (because the Moon orbits Earth roughly once a month).
At New Moon, the Moon rises at sunrise and sets at sunset, but since the lit-up side of the Moon is facing away from us, we don't see the Moon at all when it is New.
At First Quarter Moon, the Moon rises at noon and sets at midnight, so it can be seen in the sky in the afternoon before the Sun sets, and for the first half of the night.
A week later, at Full Moon, the Moon rises at sunset and sets at sunrise, so it isn't visible in the daytime, but it is visible all night long.
A week later, at Third (or Last) Quarter Moon, the Moon rises at midnight and sets at noon. So the Moon is visible in the second half of the night and in the morning after the Sun is up.
When the Moon is above the horizon, it is easier to see if it is night time than if it is daytime (since the sky itself is bright during the day), so we tend to notice it more at night. And if the Moon is a thin crescent (a few days before or after New Moon) it might not be bright enough to see against a bright blue sky. But the Moon is actually in the sky during the day just as often as it is in the sky during night.

G'day Susan S,
Thank you for your question.
The sun is 400,000 times the brightness of the moon. Yet the moon is bright enough to be seen during the day at most times of the month especially when sun light is relatively weak.
A full moon is close to invisible in the daytime because the moon is opposite the sun when the earth is between. The moon is at its brightest at night at that time. The crescent moon is too faint to be seen. The best time of day to see the daytime moon depends on its phases.
I have attached sources for your reference.
Regards

Because it is orbiting our planet, and sometimes that orbit means it is in front of the daytime part of the planet instead of the night-time part of the planet (it doesn't just pop out from nowhere when it gets dark you know).......... and I guess when it is visible in the daytime, it is because it hasenough sunlight reflecting off it (either directly from the Sun, or with additional help from light reflecting off our own atmosphere) for it to be bright enough to be seen.

The moon is almost always visible in the Western Hemisphere. Sometimes, it reflects the sun brightly enough to be seen when the direct light from the Sun to Earth is not as strong (in winter months, or cloudy/hazy days).

Moon is always there. It is light from the sun that obliterates it from viewing. Western hemisphere is the best place to view it at all times.
It is like the millions and billions of stars that you cannot see unless the city lights that pollute the sky are off. One blackout night two years ago in August, was beautiful because no lights from anywhere and I never knew so many beautiful stars are out there in the sky until that day............
