I put the date in for this event but as you can see, or I should say not see. When the moon is completely dark, it isn't visible to the naked eye. So we will say it is at it's darkest at this time, but it is also at its darkest the day before and the day after as well. People just like to have one specific reference point, and that goes for a lot of things. Yet everything is connected to everything else, and we are all slowly waking up to this realization.
