The Difference Between a Dark Moon & New Moon
There are two different schools of thought when it comes to differentiating between a new moon and a dark moon. Spoiler alert, there's not a right or wrong answer. The difference of opinion is between astronomers and Pagans. I'm going to share both schools of thought with you so you can decide what works better for you.
Here's the short answer to this query. A new moon can be a dark moon, a dark moon can be a new moon, a waxing crescent can be a new moon, but a waxing crescent can't be a dark moon. Make sense? I know, not really. Allow me to explain!
The Astronomer's New Moon
First, let's take a look at the astronomer's viewpoint. For astronomers, the new moon happens when the moon is in between, or in conjunction, with the Earth and Sun. When the moon is in between the Earth and the Sun, it appears entirely dark for us.
I know what you're probably thinking, sounds like a dark moon, right? No. For astronomers, this point of the moon cycle is considered the new moon because it marks the beginning of a new moon cycle. Most astronomers do not use the term "dark moon," there's only the new moon. This is why most moon phase calendars don't recognize a dark moon phase.
The Pagan's New Moon
For many Pagans, practicing witches, and moon followers, the dark moon happens when the moon is dark and in conjunction with the Earth and the Sun (the astronomer's new moon). The new moon follows after the dark moon phase when the moon begins to show the tiniest illumination of its waxing or growth phase.
The Importance of The Dark Moon
For Pagan's and the like, the dark moon phase marks an important phase in the cycle of the moon. The dark moon phase represents a time of rest, integration, and observance. If you're using the moon for spellwork and manifesting it only makes sense that you would work in a night or two of reflection, especially before the busy energy of the new moon.
Astronomers and Pagans obviously use the moon cycles for entirely different purposes, so it's not surprising that they recognize the phases a little differently. As I said, there's not a wrong answer here, simply different opinions for different purposes.
Your manifesting won't be thrown askew if you skip the dark moon phase, but the dark moon will offer you a sweet moment of rest.
