This apparent change in the shape of the Moon is known as its 'phase'. Because the Moon produces no visible light of its own, we can only see the parts of the Moon that are lit up by other objects. A small amount of light comes from distant stars and the reflection of light from the Earth known as Earthshine. However the main source of light for the Moon is the Sun. At almost all times, half of the Moon is being lit up by the Sun, but this need not be the half that is facing towards the Earth. The only exception is during a lunar eclipse. If the Moon is between the Earth and the Sun in its orbit, then the back side of the Moon is being lit up and the side facing the Earth is in darkness. This is called a new Moon. If the Moon is on the other side of the Earth compared to the Sun, then the near side of the Moon will be fully lit up: a full Moon. In between these, the Moon goes through multiple stages of partial illumination during its different phases. These are the banana-shaped crescent Moon , the D-shaped quarter Moon and the almost complete gibbous Moon. Finally, each phase is also named after its position in the full The full, quarter and new Moons are all the instants in time when the Moon is exactly fully, half or not at all illuminated from our perspective on Earth. The crescent and gibbous Moons each last approximately a week. A month was originally defined to be either 29 or 30 days, roughly equal to the Some of our calendar months were later padded out with extra days so that 12 months would make up one complete day solar year.
