Calculate your Lilith — free
and understand what she means in your chart
Enter your date of birth, your time and your birthplace — we calculate the exact position of your Lilith (Black Moon) in sign, house and aspects. Includes a clear interpretation of what Lilith means in your chart: your suppressed power, your "forbidden" self, your sovereignty. No sign-up, no hidden cost.
Without a time we still calculate Lilith by sign — the house placement just stays empty.
Lilith read in four layers
Lilith in your sign
The archetype of your suppressed power — the theme you learned to hide or label as "too much". Concrete interpretation for every one of the twelve signs.
Lilith in your house
The life area where Lilith shapes you most — from identity (1st house) through partnerships (7th) to transformation (8th). We name where you reclaim your sovereignty.
Lilith aspects
Conjunctions, squares and trines to Sun, Moon, Venus, Mars and the angles. Show where Lilith speaks to your conscious chart — and where she chafes.
Mean vs. true Lilith
We calculate both Lilith points: the mean Black Moon Lilith (the modern-astrology standard) and the true / osculating Lilith for a second layer of reading.
Three steps to your Lilith
Enter your birth data
Date, time and place — that is all we need. If you do not know your exact birth time, you can skip it; Lilith by sign still gets calculated, only the house needs the time.
Lilith position in seconds
We use the Swiss Ephemeris library — the same calculation standard professional astrology software runs on. Arc-second accuracy, based on the NASA DE441 dataset. Free.
Plain-language interpretation
Every position gets a concrete explanation in everyday language. What Lilith in your sign really means, the life area (house) she works in, and which aspects activate her.

Lilith calculator — frequently asked questions
- What is Lilith in astrology?
- Lilith (or Black Moon Lilith) is not a planet but the empty focus of the Moon's orbit — the point in space where the Moon is farthest from Earth (apogee). Astrologically she represents the suppressed feminine power, the "forbidden" in us, sovereignty — everything we split off as "too wild", "too angry" or "too sexual". She is the shadow that wants to be reintegrated.
- Is the Lilith calculator really free?
- Yes, fully. No credit card, no sign-up. If you want to go deeper (transits, synastry, the 30-day astrology course), there is a Pro plan — but the Lilith calculation stays free forever.
- What if I do not know my birth time?
- You can skip the time. Lilith by sign still gets calculated because Lilith stays in each sign for about nine months — even a rough estimate hits the right sign. What does not work without a time: the exact house, since houses depend on the moment of day and the place.
- Which Lilith do you calculate — mean or true?
- Both. The mean Black Moon Lilith (standard in modern astrology software) and the true / osculating Lilith. Most astrologers read with the mean Lilith, but the true Lilith reveals a second, more intimate layer — we show both and let you choose what speaks to you.
- How accurate is the calculation?
- Accurate to the arc-second. We use the Swiss Ephemeris on the NASA DE441 dataset — the same standard professional astrology software runs on. No estimates.
- What is the difference between Lilith and Chiron or the lunar nodes?
- All three are "background" points in the chart, but they show different themes: Chiron is the wound that can be healed, the lunar nodes show the soul's direction of growth, Lilith is the suppressed power that wants to be reclaimed. They complement each other — many people read all three together for a fuller picture.
