What is “New Moon Birth” and are there any differences in calculating the timing of the new moon birth by different people or different observatories?
The definition of “New Moon Birth” also known as “Astronomical New Moon” or “Conjunction” is the moment of time when the earth, sun and moon are in the same plane. In scientific terms, the Birth of New Moon is the time when sun’s ecliptic longitude and moon’s ecliptic longitude are the same with reference to the center of the earth. This could happen at any moment from 0:00 hours to 23:59 hours Greenwich Mean Time (Universal Time), and at that moment the moon is dark as seen from the earth. So, you can also think of a “New Moon” as “Dark Moon” or “Invisible Moon”. Some people calculate the ecliptic longitude of the moon and sun from a specific location on the surface of the earth. This may be called as topocentric new moon or topocentric conjunction. There are different algorithms to calculate astronomical new moon (conjunction) depending upon the accuracy desired. Some are more accurate than others. Less elaborate and sufficiently accurate formulae can calculate the birth of new moon
