Tonight – September 30, 2016 – you probably won’t see the moon because it’s at the new moon phase. Depending on where you live worldwide, this new moon is either the second of two new moons in September 2016, or the first of two new moons in October 2016. The second of two new moons in a single calendar month is sometimes called a Black Moon.

A new moon, by the way, is just a moon that’s traveling more or less between the Earth and sun. New moon is part of every monthly orbit of the moon. Black Moon is just a name, like Blue Moon, or Harvest Moon, or any moon name (although nearly all refer to full moons). It doesn’t mean the moon is literally black, although the moon isn’t shining for us now either. Because it’s between the Earth and sun, the moon’s lighted side faces away from us now, and the moon is traveling across the sky with the sun during the day.

The moon turns new on October 1 at 0011 Translate to your time zone. Although the new moon happens at the same instant all over the world, the clock time varies by time zone. At our U.S. time zones, the new moon comes on September 30, at 8:11 p.m. EDT, 7:11 p.m CDT, 6:11 p.m MDT and 5:11 p.m PDT. So, for our part of the world, the upcoming new moon on September 30 counts as the second of two September 2016 new moons.

For the world’s Eastern Hemisphere, where the moon turns new on October 1, the upcoming new moon is the first of two October 2016 new moons.

In another day or two, the moon will appear as an extremely slender waxing crescent in the western sky after sunset, to mark the birth of the Jewish New Year 5777 A.M. and the Muslim New Year 1438 A.H.

Bottom line: A Black Moon is the second of two new moons in a single calendar month. Whether you have one depends on your location on the globe. The Western Hemisphere has a Black Moon in September 2016. The Eastern Hemisphere has a Black Moon in October 2016.
