Black Moon Lilith Calculator

Your Black Moon Lilith sign and exact degree from your birth date, and its house once you add a birth time and city.

Fixes your Lilith sign and degree. It stays in your browser.

Add this and a city below and the calculator places Lilith in a house.

Only the house needs this: it supplies the latitude, longitude and time zone.

For the rest of the chart, the big 3 calculator gives your Sun, Moon and rising signs, each to the exact degree.

What is Black Moon Lilith?

Black Moon Lilith is a calculated point, and there is nothing at it: no planet, no rock, no second moon. The Moon goes round the Earth in an ellipse rather than a circle, and an ellipse has two foci. The Earth sits at one. The other is empty, and Black Moon Lilith marks the direction of that empty focus, which is also the direction of the Moon's apogee, the point where it swings farthest from us. When an astrologer puts “Lilith” in a sign, this is what they mean: a direction in space, with nothing to see when you look.

Because it is an orbital point rather than a body, Black Moon Lilith drifts only about a ninth of a degree a day and takes roughly nine years to go once round the zodiac. Your birth date alone fixes its sign and degree, and the birth time makes no difference to either. The time and city come in for one thing, the house, because whole-sign houses are counted from your rising sign.

What Black Moon Lilith means in astrology

The name comes from the Lilith of myth, who refused to be anyone's subordinate, and astrologers read the point accordingly: as the raw, instinctive part of you that declines to be tamed, shamed or made convenient. The sign says how that streak shows itself and the house says where in life it tends to surface. Most modern astrologers treat it as the opposite of a curse. It marks the place you are invited to take back the desire and the authority you learned, somewhere along the way, to put down.

The frame matters. The point is real astronomy and the calculator treats it that way. What it means is a tradition, a language for thinking about yourself rather than a measurement or a sentence. Read it as a mirror worth a few minutes in front of, and be wary of anyone who reads it as a verdict.

Mean vs True Black Moon Lilith

Here is the detail most calculators skip. There are two common ways to compute Black Moon Lilith. Mean Lilith follows the Moon's average orbit and moves in a smooth, steady line. True (or osculating) Lilith follows the orbit's actual moment-to-moment wobble, so it speeds up, slows down and sometimes runs backwards. The two can sit up to about 30 degrees apart, and sometimes in different signs altogether.

That is a big enough gap to change a reading, so it matters that a tool says which one it uses, and most do not. This calculator computes Mean Black Moon Lilith, the more widely used default and the one many printed ephemerides show, and it always prints the exact degree so you know what you are looking at. I compute Mean, say so, and show the degree, rather than print a True value I could not stand behind to the arcminute.

Black Moon Lilith through the twelve signs

How Mean Black Moon Lilith reads in each sign, in short. Find your sign with the calculator above and look it up here. None of it is a warning.

Lilith in Aries

Refused anger

Lilith in Aries is anger you were told to put away. Somewhere early, wanting things loudly got labelled too much, so the wanting went underground and came back as a low, permanent impatience. The disowned part here is plain appetite, for a fight and for first place. People with this placement often describe learning, late, that a clean no is kinder than a swallowed yes.

Lilith in Taurus

Unapologetic appetite

The body, money and pleasure. Lilith in Taurus sits in all the things you were taught to want quietly. Astrologers read this as appetite that was shamed early, for food, for comfort, for money, for having enough and then some. The refusal that follows is a refusal to be owned, by a salary or by anyone who pays it. The work, if you want it, is enjoying what you have without apologising to anyone for it.

Lilith in Gemini

The forbidden question

With Lilith in Gemini the disowned thing is your mouth. Somebody, once, found your questions inconvenient or your cleverness rude, and you learned to tone the sentence down before it left. Astrologers read this as the forbidden question, the thing everyone at the table knows and nobody says. You are the one who says it. The shame attached to being too curious was never yours to keep.

Lilith in Cancer

Need without strings

Lilith in Cancer puts the refused part in the kitchen: hunger for belonging, and the wish to be looked after that got called clingy. People with this placement often describe a fierce, protective streak under a mild surface, and a suspicion of any care that arrives with conditions attached. The thing to reclaim is the right to need people and still be nobody's property. Both. At the same time.

Lilith in Leo

Refused applause

Lilith in Leo is the wish to be adored, which at some point got renamed showing off. So you dimmed it, and the dimming leaks out sideways as a grievance about not being seen. Astrologers read this placement as pride you were shamed for and play you were told to outgrow. The disowned part is the child who wanted the whole room. Let that child have a chair at the front.

Lilith in Virgo

Kept imperfections

Lilith in Virgo lives in the body and the to-do list. The shamed thing is imperfection: the mess, the day off, lunch eaten standing up, the typo. Astrologers read it as a pull between being useful and being free, with a critic who never clocks off. The disowned part is the you that is good enough unfinished. Serving because you chose to differs from serving because you owe it, and you are allowed to notice which is happening.

Lilith in Libra

Wants over peace

Lilith in Libra is desire that was traded for peace. You learned early to be agreeable, and the price was that your own wants went missing from the negotiation. The disowned part is the one who wants the argument and the bigger half. Astrologers read this placement as reclaiming an equal seat in every partnership, including the right to be unfair once in a while and see what happens.

Lilith in Scorpio

Untamed intensity

Scorpio's usual territory, sex, power, secrets and death, overlaps almost entirely with Lilith's, so astrologers treat Lilith in Scorpio as the same signal turned up. The shamed thing is intensity itself: wanting too much and seeing through people too fast. People with this placement often report a horror of being controlled and a pull toward the depths everyone else edges away from. The refusal here is the refusal to be tamed, and it is doing its job.

Lilith in Sagittarius

The heretic

Lilith in Sagittarius is the belief you were not supposed to hold. The disowned part is the heretic: the one who asked the preacher a question and then left the country, trusting their own experience over the book. Astrologers read this placement as truth said too bluntly and freedom taken without permission. The shame attached to needing room is old and it was never accurate. Take the room.

Lilith in Capricorn

The disowned boss

Lilith in Capricorn has a difficult relationship with the person at the head of the table. Astrologers read it as ambition you were shamed for, or authority you learned to distrust and want in the same breath. The disowned part is the boss. People with this placement often describe having to earn every inch and resenting the ladder while climbing it. Becoming your own authority means the ladder stops being the point.

Lilith in Aquarius

Chosen strangeness

With Lilith in Aquarius the shamed thing is your strangeness: the ways you do not fit, and would not if you could. Somewhere you learned to file the rebellion down to stay in the group, and it did not work, because the group could tell. Astrologers read this as the outsider reclaimed. The difference is the point, and the rules worth breaking are usually the ones that required you to be smaller.

Lilith in Pisces

Bounded longing

Lilith in Pisces is the longing to dissolve. Into a person, a cause, a fog, a bottle, anything that stops the edges hurting. Astrologers read this as compassion without limits and the shame of needing more than seems reasonable. The disowned part is the one who wants to escape, and the work is giving that wish a boundary rather than a cage. Feel all of it. Keep one hand on the door.

Black Moon Lilith questions

The questions people ask, including the Mean-versus-True one most sites skip.

What is Black Moon Lilith?

It is a point in space rather than a body. The Moon's orbit is slightly egg-shaped, and the mean lunar apogee is the spot where that orbit carries the Moon farthest from Earth, averaged out over time. Black Moon Lilith is the name astrologers give that point, or, in the same direction, the empty focus of the ellipse. Nothing is there to look at. Astrologers read it as the raw, untamed part of you that got hidden early.

What does Black Moon Lilith mean in astrology?

Astrologers read Lilith as the part of you that refuses: the appetite you were told was too much, the anger you were told to put away, the self that would rather be disliked than made convenient. Its sign says what that part wants; its house says where in life it tends to surface. None of it is a curse or a verdict, and none of it is fixed. It is a map of where you stopped apologising, or could.

How do I find my Black Moon Lilith sign?

Enter your birth date above. The calculator computes Mean Black Moon Lilith and shows the sign and the exact degree. Lilith moves only about a ninth of a degree a day, so the date on its own settles both, and the hour of birth does not come into it. Add a birth time and city and the calculator also places Lilith in a whole-sign house, which astrologers read as the area of life where its themes show up.

Do I need my birth time for Black Moon Lilith?

Not for the sign or the degree. Lilith drifts so slowly that the date alone fixes both, whatever time of day you arrived. The time and city matter for one thing only, the house, because whole-sign houses are counted from the rising sign and the rising sign changes through the day. So with just a date you get an accurate Lilith sign and degree, and a blank where the house would go.

What is the difference between Mean and True Black Moon Lilith?

Mean Lilith follows the Moon's averaged orbit, a smooth line that only ever moves forward. True, or osculating, Lilith follows the orbit as it actually wobbles from moment to moment, and it can jump ahead and drop back. The two can sit up to about thirty degrees apart, sometimes in different signs. Most sites do not say which one they use. I compute the Mean position, the more common default, and show the degree so you can tell.

Is Black Moon Lilith the same as the asteroid Lilith?

No, and the name is doing a lot of work. Three separate things carry it. Black Moon Lilith is the mean lunar apogee, a point in space, and the one this calculator computes. Asteroid 1181 Lilith is an actual rock in the asteroid belt. The Dark Moon Lilith, sometimes called the Waldemath moon, is a hypothetical second moon of Earth that nobody has found. A Lilith reading depends entirely on which one a site actually calculated.

Is Black Moon Lilith bad?

No. Lilith has a fierce reputation, mostly inherited from the myth. Astrologers increasingly read the placement the other way round: as the instincts, desires and plain wants you were taught to hide, and the point in the chart where you take them back. The sign and house can mark a tender spot. Tender is a reason to look closer. It is a mirror, and mirrors do not hand down verdicts.
