What the calculator shows about your chart
You don’t need another polite horoscope telling you that you’re a misunderstood angel. Enter your birth details to see your mean Lilith, true Lilith, rising sign, Placidus house, and return dates. Take a fictional chart for February 18, 1999, at 7:14 AM in Los Angeles with 12°17′ Pisces rising.
That chart puts mean Lilith at 18°02′ Scorpio in the 8th house of sex, shared money, and taboo. Fixed water ruled by Mars and Pluto doesn’t forgive slights or split control fifty-fifty. You sniff out hidden motives before anyone else in the room even notices a threat. It makes you ruthless in intimacy, yet impossible to con twice.
Mean vs true Lilith and why your sign changes across apps
Another site probably gave you a different Lilith sign and never bothered to explain why. Mean Lilith tracks the Moon’s smoothed lunar apogee, and that’s our main method when we name your Lilith sign. True Lilith tracks the instantaneous orbit, which wobbles enough to land in another sign 36.2% of the time.
Across 1508 moments from 1900 to 2100 in Swiss Ephemeris 2.10.03, the median gap between them is 9.8°. About 95% of gaps stay under 25.2°, while the largest gap reaches 29.9°. In our February 18, 1999 example, mean Lilith is 18°02′ Scorpio while true Lilith sits at 27°45′ Libra. That’s fixed water trading blows with cardinal air ruled by Venus, all inside the same 8th house.
No birth time: what you still get
If your mom forgot when you were born, you still get your Lilith sign. Mean Lilith moves about 40 degrees a year and changes sign within a single day on 0.3% of days. True Lilith swings from -3.6 to +6.3 degrees per day and crosses a sign boundary on 7.3% of days.
What you lose without a birth time is your Placidus house placement, because houses turn every couple of hours. Without a time, we can’t tell if Mars-ruled Aries wrecks your 7th house partners or 10th house career. You still get your sign’s raw instinct and the sharpest weapon in your personality.
Lilith returns and when your villain era hits
Everyone blames their Saturn return for their late-twenties mess, but your Lilith return strikes first. Mean Lilith circles the zodiac every 8.85 years, hitting its natal degree at ages 8.8, 17.7, and 26.5. Then it comes back around at ages 35.4 and 44.2 to test what you still refuse to tolerate.
For our February 18, 1999 chart, those returns hit on December 25, 2007, October 30, 2016, September 4, 2025, July 11, 2034, and May 17, 2043. When transiting Lilith crosses your natal degree, astrologers read it as the appetite you buried for polite company pulling at its leash. Use the year to burn down the compromises that cost you too much.
Questions
What house is my Lilith in?
That depends on your birth time and city, not just the date: Placidus houses turn every couple of hours, so two people born on the same day can have Lilith in different houses. Enter all three above and the result names your house and degree. In our February 18, 1999 example, 7:14 AM in Los Angeles puts mean Lilith in the 8th house.
When is my Lilith return?
Mean Lilith comes back to its birth degree every 8.85 years, at about ages 8.8, 17.7, 26.5, 35.4 and 44.2. The calculator lists your own return dates under the result. In our sample chart they fall on December 25, 2007, October 30, 2016, September 4, 2025 and July 11, 2034.
Which Lilith does this calculator use as my main Lilith sign?
Your main Lilith sign on this site is mean Lilith, the smoothed lunar apogee. We also calculate true Lilith right beside it so you can see the exact degree gap. That way you know why another chart gave you a neighboring sign.
Where is Lilith right now?
Mean Lilith entered Capricorn on September 14, 2026, and stays there until June 11, 2027, when it enters Aquarius. Saturn-ruled cardinal earth puts status and ambition under the spotlight: it exposes who climbs for respect and gives you the stomach to run the room. The exact degree for today is under the orbit at the top of this page.
Do you save my birth date or location when I run the calculator?
No, the math runs locally and nothing leaves your device. There’s no account to create, no email wall, and no database hoarding your birth chart. You get your sign, Placidus house, and return dates without handing over your personal data.
Why are my mean Lilith and true Lilith in different signs, not houses?
Their median separation is 9.8°: enough to cross a sign border, not always enough to change the house. In our February 18, 1999 example, 18°02′ Scorpio and 27°45′ Libra both sit in the 8th house. Your style shifts between Mars-ruled fixed water and Venus-ruled cardinal air, while the arena stays intimacy.
What if I was born on the day Lilith changed signs?
Mean Lilith changes sign within a day on 0.3% of days, while true Lilith shifts on 7.3% of days. If your birthday lands on an ingress date, a noon default can miss the exact hour it crossed 0°00′. Enter your birth time and city here to see which side of the cusp you landed on.
Does a hard Lilith placement mean someone is a bad partner?
A placement shows a temptation—like Taurus possessiveness—and where your boundaries hold firm. Still, behavior matters more than any sign, and astrology never excuses control or abuse. Anyone who feels unsafe can reach The Hotline at 1-800-799-7233 or thehotline.org.
