Aside from the fact that the Moon, Earth and Sun don't orbit all in the same plane (as mentioned by Quora User's answer) there are two more reasons why the full moon can be seen during the day: 1  The full moon happens, as you correctly state, when the Sun, Earth and Moon are aligned.  That's no (full) moon!
In order for the moon to be visible in the sky, it needs to be above the horizon. On average, the moon is above the horizon for 12 hours a day. Some of those 12 hours are bound to coincide with the sunâsâproducing a daytime moon. Which, despite how exciting it can be to see, isnât that rare. In fact, the moon is visible during the day nearly every day, except for when itâs close to a new moon or is a full moon.
