The moon is always half lit as it revolves around the earth. When the moon is directly between the earth and the sun we can not see the side that is in sunlight because it faces away from us. As it continues to rotate around the earth we see more and more of the lighted side of the moon. When it finally gets to the point directly opposite the sun, we see the whole lighted moon, or the full moon. As it continues to rotate we see less and less of the lighted side until it is again directly between earth and the sun, and we see no moon at all: the new moon, or dark of the moon. It takes 14 days for the new moon to become a full moon, so it would take about 12 days for a crescent moon to become full.
