No moon day, also known as the new moon, occurs due to the alignment of the moon with the sun, making the side of the moon that faces Earth unilluminated. This alignment means the sun and moon are on the same side of Earth, and the sunlight is unable to reach and reflect off the moon’s surface to be visible from our perspective. Essentially, the moon is there, but it's cloaked in the sun’s shadow from our view.
