What Is a Black Moon? (2024)

It’s a “Black Moon”! This sounds ominous but it’s not. Find out what a Black Moon is, when the next Black Moon occurs, and special symbolism andfolklore.

What is a BlackMoon?

A Black Moon is a special kind of New Moon, just as aBlue Moon is a special kind of Full Moon. Neither are astronomical terms; both are catch phrases for an unusual lunar calendar occurrence. For this reason, the definition of a Black Moon can vary and may referto…

1. …the secondnew Moonin a month. This is the definition of Black Moon that’s used most often, and it’s the most common (once every 29 months).
   
2. …the third new Moon in a season of four New Moons. Every season (spring, summer, fall, winter) has 3 months and 3 new Moons. However, occasionally (every 33 months), there is a season with 4 new Moons. In this case, the third New Moon is called a Black Moon.
   
3. …when there are NO new Moons in a month (February). This can only happen in February since it’s the only calendar month that is shorter (28 days) than the lunar month. When there is not a new Moon in February, there will be two new Moons for both January and March. It’s a rare occurrence (every 19 years or so) and the next one isn’t until 2033.
   
4. …every new Moon, since we’re then seeing the Moon’s dark or blackside.

What Will You See During a BlackMoon?

Black Moons are invisible, like all new Moons, so you won’t see the Moonitself!

Did You Know: The new Moon always rises near sunrise, and crosses the sky with the Sun during the day, so the glare of the Sun is too strong. See our handy chart on “When Will the Moon Rise Tonight?”

Remember, there are four quarters of the Moon—theMoon phases. There’s usually anew Moon and a full Moon about once a month, because the Moon takes about a month to orbitEarth.

• With the “full Moon,” the entire disk of the Moon is illuminated by the Sun (because the two celestial objects are on opposite sides of thesky).
• In contrast, the “new Moon” has its dark side facing us. It’s not reflecting any of the Sun’s lightbecause the Moon is lined up between the Earth and Sun. Only the far side of the Moon is illuminated, and we can’t see this side fromEarth.

Stars LookBrighter

Although you can’t see the Black Moon, the good news is that a moonless sky is excellent for stargazing (since the Moon’s light won’t drown out thestars).

A day or two after the new Moon, you’ll see the slim crescent Moon in the west after sunset. This is such a magical moment. Often you’ll not only see the crescent but also the darkened area of the Moon’s disk shining dimly. The reflected light is called “Earthshine.”

Black MoonInfluence

As the Black Moon is a new Moon, there are some special practices and folklore associated with this time of the lunarcycle.

• For example, according the age-old practice of Gardening by the Moon, one should plant vegetables that bear crops above ground during the light: from the day the Moon is new to the day it is full.
  
• There is also folklore about the new Moon and good luck. Some folks considered this to be a special time when any activities are more powerful and effective, and other believes this is a time when activities should not be conducted!
  
• Of course, there are also religions which follow a lunar calendar and pay special attention to the new Moon. After the Moon’s absence for a few days, it’s kind of a lunar rebirth. Thus, some cultures revolved ceremonies around that first appearance of the newMoon.
