What is Black Moon Lilith?
Black Moon Lilith is not a planet or an asteroid. It is a point in space: the spot in the Moon’s orbit that is farthest from Earth, also called the lunar apogee. The name comes from Lilith of folklore, a figure who refused to submit.
In astrology Lilith is linked to your raw, unfiltered side: what you refuse to hide, the things you were told to tone down, and where you feel most strongly about independence.
Which Lilith does this calculate?
This calculator gives the mean Black Moon Lilith, the smooth average position used by most chart apps and astrology sites. A “true” or “osculating” Lilith also exists, which swings back and forth by several degrees and can sit in a different sign. Not to be confused with the asteroid Lilith or the Dark Moon.
The mean Lilith takes about nine years to go around the zodiac, so it spends roughly nine months in each sign.
Frequently asked questions
How is my Lilith sign calculated?
The calculator uses the standard formula for the Moon’s mean apogee (from Jean Meeus, Astronomical Algorithms), converted to the tropical zodiac.
Is this mean or true Lilith?
Mean Lilith. It is the most widely used version. True (osculating) Lilith is not offered here yet.
Do I need my birth time?
Mean Lilith moves about 0.11 degrees a day, so it changes sign only about once every nine months. If that happens on your birth date, the calculator shows both signs and asks for a time.
Is Lilith the same as Black Moon Lilith?
In this calculator, yes. Some astrologers also use an asteroid called Lilith; that is a different thing.
What dates does the calculator cover?
Birth dates from 2 January 1900 to 31 December 2099. Outside that range the calculator will say so rather than guess.
Is this scientifically proven?
No. The position is an astronomical calculation; the meanings are astrological tradition. Use them for fun and reflection.
