Lilith Sign Calculator

Enter your birthday to find the sign and degree of your Black Moon Lilith.

Your Lilith sign is the zodiac sign that held Black Moon Lilith when you were born. Black Moon Lilith is not a planet or a moon. It is the direction of the point on the Moon's orbit that lies farthest from Earth. Astrologers read its sign as the side of you that refuses to be tamed. To find it, you only need your date of birth.

How the calculator works

The Moon's path around Earth is an oval, with Earth off to one side of the centre. At its nearest, the Moon is about 363,000 kilometres away. At its farthest, a point called the apogee, it is about 405,000 kilometres away. Black Moon Lilith is the direction of that far point as seen from Earth, measured against the zodiac. You will also see it described as the empty second focus of the Moon's orbit. Seen from Earth, both lie in the same direction, so the two definitions give the same sign and degree.

The whole oval turns slowly. The far point travels forward through the zodiac and takes 8.85 years to go all the way round, about 41 degrees a year. That puts it in each sign for roughly nine months: between 1930 and 2040, every stay lasts 268 to 271 days.

Mean Lilith and true Lilith

The Sun pulls on the Moon and keeps bending its orbit out of shape, so the real far point does not advance smoothly. It lurches ahead and falls back, by as much as 30 degrees either side of its average position. Astrologers deal with this in two ways.

• Mean Lilith is the average position, moving at a steady pace. Most astrologers and most calculators use it, and it is the headline result here.
• True Lilith, also called osculating Lilith, is the far point of the orbit the Moon is following at that instant, swings included.

The two are in different signs 36% of the time, which is the usual reason two calculators give different Lilith signs for one birthday. This calculator shows both and tells you when they disagree.

We give true Lilith to the nearest whole degree. Its position is very sensitive to tiny changes in the Moon's speed, and when we compared ours with positions worked out from NASA Jet Propulsion Laboratory orbit data at 4 dates, the largest gap was 0.14 degrees. Mean Lilith comes from a standard formula for the Moon's orbit and is given to the arcminute.

Two other points called Lilith

The name is shared by three different things, and they are easy to mix up.

A worked example

Take someone born on June 15, 1995. Mean Lilith was at 18°11′ Gemini that day. It had entered Gemini on January 2, 1995 and stayed until September 29, 1995, so everyone born between those dates has Lilith in Gemini. True Lilith was at about 15° Gemini, in the same sign.

Mean Lilith came back to the same degree on April 19, 2004, when that person was 8. That is a Lilith return. The following ones fall on February 23, 2013 and December 29, 2021, at ages 17 and 26.

Lilith sign dates, 1930 to 2040

Find the row that contains your birthday. Dates are for mean Black Moon Lilith, in Universal Time. If you were born on a date in the table, add your birth time in the calculator to see which side of the change you fall on.

What each Lilith sign means

Black Moon Lilith entered astrology in the twentieth century, so it has no ancient tradition behind it and authors differ. These are the themes that come up most often. They describe what a person was pressed to hide, and where they tend to stop complying.
