What is the new moon in the constellation?

On the 30th or 1 day of each month in the lunar calendar, the moon lies between the sun and the earth. People on earth only see the moon deviating from the dark side of the sun, so they can't see the moon on earth, which is called a new moon or a new moon.

On the fifteenth and sixteenth day of the first lunar month, the moon moves to the outside of the earth, that is, the sun and the moon are located on both sides of the earth. Because there is an angle θ between the ecliptic plane and the ecliptic plane, under normal circumstances, the earth can't stop the sunlight, and the bright side of the moon all faces the earth, so people can see a bright moon, which is called the full moon or the moon.

In astrology, the influence of new moon and full moon on constellation 12 is different.
