Lilith Sign Calculator: Your Black Moon Lilith

What is Black Moon Lilith?

Black Moon Lilith is the lunar apogee - the point in the Moon's elliptical orbit farthest from Earth - projected onto the zodiac. It takes about 8.85 years to circle the chart. In modern astrology Lilith carries the myth of Adam's first wife, who refused to be subordinate and left Eden: the placement is read as your raw, untamed side - where you will not be controlled, what you desire without apology, and where early shame can turn into power when you own it.

One honest complication: there are several 'Liliths'. This calculator uses Mean Lilith - the smoothed apogee, and the version most books, courses and astrologers mean when they say 'Lilith sign'. The True (osculating) Lilith wobbles around the mean by up to a full sign because the Sun's gravity tugs the Moon's orbit around, which is why two websites can give you different Lilith signs and both be 'right' about different points. There is also an asteroid named Lilith (1181) - a different thing entirely.

How this calculator works

Mean Lilith is a formula, not a lookup: the Moon's mean apogee longitude is computed from its mean longitude and mean anomaly (standard Meeus lunar elements), giving a smooth point that never turns retrograde. The calculator evaluates it at your birth moment - your time zone only matters if you want the degree to the arc-minute; the sign is settled by the date for all but edge cases, which are flagged.

Frequently asked questions

Why did another site give me a different Lilith sign?

Almost always the mean-vs-true difference. This calculator shows Mean Lilith, the standard default. True (osculating) Lilith tracks the Moon's real, wobbling apogee and can sit up to about 30 degrees - a full sign - away. Neither is a mistake; they are different points. Most astrologers quote the mean position in conversation.

Do I need my birth time for my Lilith sign?

No - Mean Lilith moves about a degree every nine days, so the date alone settles the sign unless you were born within a day or so of a sign change. A birth time only sharpens the degree.

Is Lilith a planet or an asteroid?

Black Moon Lilith is neither - it is a mathematical point, the Moon's apogee (with an empty orbital focus as its twin definition). Separately, there IS an asteroid 1181 Lilith in the main belt; some software lists it too, which adds to the confusion. This page is about Black Moon Lilith.

What does my Lilith sign mean?

Traditionally: the style of your untamed side - what you refuse to suppress, where you meet shame and turn it into self-possession, and the raw desire you are learning to own without apology. The reading under your result gives the traditional flavour for your sign.

How often does Lilith change sign?

Roughly every nine months - a full zodiac circuit takes about 8.85 years, the same period as the Moon's apogee cycle. That is much faster than the outer planets, which is why Lilith feels more personal than a generational placement.

ToolFoxHub astrology calculators are for entertainment and self-reflection. Astrology is a symbolic tradition, not a science, and these readings are traditional interpretations, not facts or advice. Positions use the tropical zodiac and standard astronomical formulas (Jean Meeus) computed in your browser - nothing you enter leaves your device. Results agree with professional ephemerides for the great majority of births; if you were born in the short window when a body was changing sign, your exact birth time and place decide the answer, and the calculator says so when that is the case.
