august 21st is likely the only true black moon ( is one every 29 months approximately and a different one every 36ish months, not to be confused with the "new moon" that happens almost each month) that also coincides with a total solar eclipse during the middle of the day that most of us will ever see in our lifetimes.
its trajectory goes from west to east coast as well so the entire land of righteous americans will be able to enjoy it and the good fortune associated with it, probably a reward for merican heroes for not electing hillary clinton.
