TWO BLACK MOON MODELS, ONE CHECK
Lilith Sign Calculator

LOADING MODELTwo labels, checked together.
Enter your birth details to calculate Mean Black Moon Lilith and True (osculating) Black Moon Lilith side by side.
THE CALCULATION
One input, two named models.
This lilith sign calculator runs a tropical, geocentric Swiss Ephemeris calculation locally in your browser. It reports the mean lunar apogee (SE_MEAN_APOG) and the osculating lunar apogee (SE_OSCU_APOG) at the same calculated UTC moment.
These are two Black Moon Lilith models, not two names for asteroid 1181 Lilith. A sign may agree in both outputs or differ near a sign boundary. The page shows both rather than silently choosing one.
How to check what another chart service defaults to
- Open the object list or settings in that service—not only the chart wheel.
- If it says Mean Lilith, Mean Black Moon, or Mean Apogee, compare its degree with this page’s Mean result.
- If it says True Lilith, Osculating Lilith, or Osculating Apogee, compare it with this page’s True result.
- If it labels the point only Lilith, its default is not stated. Record the degree and check which of the two displayed results it matches.
Dates from 1 January 1800 through 31 December 2399 are accepted. A missing birth time uses local noon as an estimate; use a recorded time when a result sits close to a sign boundary. A manually entered UTC offset is required because historical daylight-saving rules are not inferred.
KEEP THE LABEL PRECISE
Questions before interpretation.
What is a black moon lilith calculator calculating?
It calculates a lunar-apogee point, not a physical asteroid. This page gives both the Mean and True/osculating versions so you can identify the model behind a chart label.
Why do two Lilith calculators show different signs?
They can use different birth inputs, zodiac settings, or Black Moon models. Check the exact object label and degree before treating a sign difference as an error.
Can I calculate Lilith without a birth time?
Yes, this page uses noon at the UTC offset you enter and visibly marks the result as estimated. The model comparison still works, but a boundary case needs the recorded time.
Is Black Moon Lilith the same as asteroid 1181 Lilith?
No. Asteroid 1181 Lilith is a different object and is not calculated by this page.
