New Moon occurs on the 2nd at 9:31 pm Eastern Standard Time. … On the evening of the 3rd you’ll have the rare opportunity to sight a very young crescent Moon. If you look about five degrees above the west-southwest horizon at around 6:00 pm EST you may be able to spot the 21-hour-old crescent as a thin, hair-like gash of light against the twilight sky. A very clear atmosphere and an unobstructed view of the horizon are essential to accomplish this feat, and a pair of binoculars will make it a little easier.
