Still having questions or not understanding Dark Moon versus New Moon? Most calendars do not notate the Dark Moon.
The Dark Moon completely disappears from sight every month when the Moon and the Sun line up above Earth. The longitudinal alignment of both bodies means the sunlit face of the Moon faces away from our planet. During a Dark Moon, the lunar orb is effectively invisible to the naked eye for one or two nights at a time. This occurs about every 29 days and is the stellar opposite of the Full Moon.
We are about to experience a Dark Moon on 11/7/18 – look up as you will but on this night the moon will seem invisible, hence Dark Moon.
As soon as a sliver of light appears, the moon is then New and builds towards the Full Moon (11.23.18).
