Phases Of Moon / Moon Cycles (चंद्र कलाएँ)

Astronomically the revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. From Earth we see the Moon grow from a thin crescent to a full disk (or full moon) and then shrink back to a thin crescent again before vanishing for a few days. 
The Moon do not have light of its own , it simply reflects light of Sun .While watching from earth Moon appears to change shape because of the different angles from which we see the brighter part of the Moon. This is called Phases of Moon. The phases of the Moon correlate with its angular distance from the Sun. The Moon phases are produced by the alignment of the Moon and the Sun in the sky.
At new moon (अमावस्या), the Moon is lined up between the Earth and the Sun. We see the side of the Moon that is not being lit by the Sun (in other words, we see no Moon at all) 
As the Moon moves eastward away from the Sun in the sky, we see a bit more of the sunlit side of the Moon each night.
