This cycle has been appropriately named the 'dark moon'. The cycle from one dark moon to the next is called a lunation and an average lunation calculates at about 29 days, 12 hours, 44 minutes and 3 seconds (roughly) To be fair, it does deviate in relation to the moons erratic orbit patterns and is affected by the gravity conflict between the sun and the moon.
The magic of the New Moon is the promise of redemption and a new start. For me it is the time of the month I use for some inner contemplation of where I am and where I want to go with my life. It is a great time to decide on what is really important for me and where I want to put more attention towards. The goals I set for myself can grow towards manifestation and ripen with the Moon growing into its full glory.
The discovery of a moon can lead to a treasure chest filled with valuable information about the dwarf-planet system. This is because, by measuring the moon's orbit, astronomers can then go on to calculate a mass for the system and gain an important insight into its evolution.
