The moon does not absorb light during the day and emit it at night. The moon is a rocky, airless body that reflects sunlight. When the moon is facing the sun, the side of the moon that is facing the sun is lit up, and the side of the moon that is facing away from the sun is dark. As the moon orbits the Earth, different parts of the moon are lit up by the sun, and different parts of the moon are dark. This is why we see different phases of the moon, such as the full moon, the new moon, and the crescent moon.

The moon does not emit its own light. Instead, it reflects sunlight. The amount of sunlight that the moon reflects depends on the phase of the moon. When the moon is full, it is reflecting the most sunlight, and when the moon is new, it is reflecting the least sunlight.
