What is a black moon?
"Black moon" is a popular name, not an official astronomy term. It most often means the second new moon in a single calendar month, the dark counterpart of a blue moon (often defined as the second full moon in a month). It is also used for a month with no new moon at all, which can only happen in February.
At new moon 🌑 the Moon sits between Earth and the Sun, so its sunlit side faces away from us and it is practically invisible. That is why a black moon never looks special in the sky: there is nothing to see.
Black Moon Lilith ⚸ in astrology
In Western astrology, Black Moon Lilith is not a real object but a calculated point: the lunar apogee, the place in the Moon's orbit farthest from Earth. Astrologers place it in a birth chart much like a planet. Its glyph ⚸, a dark crescent above a cross, was added in Unicode 5.1.
Do not mix it up with ☊ and ☋, the ascending and descending lunar nodes, where the Moon's path crosses the Sun's apparent path across the sky. The twelve signs themselves are on the zodiac sign symbols page.
Solid or outlined: how dark moons display
☽ and ☾ are text characters, so their color follows your text and their shape depends on the font: some fonts draw a solid black crescent, others an outline. If you need a moon that is always dark, use the emoji 🌑 or 🌚, or a black circle ● for a minimal new moon.
Dark moons fit gothic, witchy and night-owl bios. Mix them with bats, candles and black hearts, browse the witch symbols, or go back to the full moon symbol collection. In Word, type 263D and press Alt + X for ☽.
