Questions

Before you cast.

Is Stellar free?

Yes. You can cast your birth chart, read your daily sky and see this month's lucky days for free, with no account. Paid plans add more saved charts, deeper readings, the progressed chart and astrocartography.

Do I need my birth time?

A birth time gives you the Ascendant, the Midheaven and the twelve houses, which is where a chart becomes personal. It is worth finding: a birth certificate or a parent usually has it.

What if I do not know my birth time?

Leave it blank. Stellar casts the natal chart for noon, places every planet in its sign, and still writes your reading. Add the time later and the houses fill in.

What house system do you use?

Placidus or whole sign, your choice, switched with one tap on any chart. In whole sign the first house begins at 0 degrees of your rising sign and the Ascendant is marked at its true degree.

Is this a sun sign horoscope?

No. The daily transit reading looks at where today's planets fall in your own houses and what they touch in your natal chart, so two people with the same sun sign get different readings.

Can I save more than one chart?

Yes. Two charts are free, for you and someone you love. Star Gazer keeps three, Star Reader ten, and Deep Sky as many as you like, in folders if you want them.

Does it work on my phone?

Yes. Stellar is an astrology chart app that runs in the browser on any phone, tablet or computer, and your charts follow you between them when you sign in.

Do you sell my data?

No. Your birth details are used to cast your chart and are never sold to anyone.

New here? How to read your chart
You are the universe in relationship with itself

Measured from where you happened to take your first breath, or be born. You are a crystallisation of one particular moment of time and space, the point where something non-physical takes a physical shape. Here is how to read it.

What you are looking at

A map of the sky from the exact spot where you were born, at the exact minute. Not the sky in general. The sky from there, then. Three markers do most of the work.

The Ascendant is the point on the eastern horizon at the moment you arrived. It moves about one degree every four minutes, which is why your birth time matters more than any other detail here.

The Midheaven is the highest point the sky reached over that place at that moment. It comes from the same time and place calculation as the Ascendant, and it points at what you are visibly moving toward.

Those two anchor the wheel, and the twelve houses are built from them. The houses are the areas of life. Without a birth time there is no reliable Ascendant, so there are no reliable houses, and a good half of what this chart can tell you goes quiet.

The Sun is where you are most alive. Whatever sign and house it sits in is where your energy runs cleanest, and where you recharge by doing rather than resting.

Three planets worth knowing by name

Your ruling planet rules the sign on your Ascendant. It is the planet you are most attuned to, and wherever it sits in the chart is a place you keep returning to.

Your rising planet is the one that rose just before the Sun on your birth morning. Traditionally this is called the oriental planet.

Your leading planet is the one at the front of your chart's overall shape, the one everything else follows.

Between them they describe how you start, how you work, and what you lead with.

If you do not know your birth time

Ask family, or check your birth certificate, which records it in many places. Failing that, astrologers use rectification, working backwards from events you can date to find the time that fits. We are building a questionnaire to help with that, and it is coming.

Until then the chart still works for signs and planets. It is the houses and the angles that need the time.

Your reading
Reading your chart
Your planets & angles

Every planet plus your Ascendant and Midheaven: sign, house, exact degree, and what each one means for you. The colored tags name each planet's classical dignity where it has one: in domicile, exalted, in detriment or in fall. Where none applies, the tag grades its blended strength instead, stronger or more challenged. Hover or tap any tag to learn what the term means. Untagged planets stand on neutral ground.

Your houses

All twelve houses of your chart: the sign on each cusp, who lives there, and what an empty house actually means.

Houses & signs: how yours interlock
Your chart's overall shape
Your ruling, rising & leading planets

Three planets that go first in your chart. Your ruling planet rules your Ascendant and is the one you are most attuned to. The rising planet rises just before the Sun and shapes how you meet the world. The leading planet sits just past the largest gap and drives your chart like an engine. All three can shift as your chart progresses.

Your aspects

The angles your planets make to each other: conjunctions, sextiles, squares, trines and oppositions, each with what it means for you.

Other bodies

Each point read in full: what it is, how it moves in its sign, the house it lives in, and how it behaves under transit.

Love, money & career
Lucky times in your life

The standout fortunate windows of your life. No single planet makes a lucky time — these are the stretches when many quiet signals in your chart line up at once.

A word first: your luck is yours to make. These windows are favourable weather, not a promise — and some of the luckiest sit on the other side of hard work. Show up for them, and they open.

Your luck rating ✦

Your baked-in luck from the birth chart is the headline; the luck of the moment layers on top. Rated as a percentage and capped at 95%, because life always keeps a little chance of its own.

Your decans ✦

Every sign splits into three ten-degree decans, each coloured by another sign of its own element. It is a finer layer than your sign but coarser than your exact degree: same core nature, a distinct sub-flavour depending on where in the sign you fell.

Your degree meanings ✦

Every one of the zodiac's 360 degrees carries its own signature. Here is the exact degree each of your placements occupies, read one by one. Based on Esther Leinbach's degree system.

Your fixed stars ✦

The great named stars hold almost still while the planets wheel past them. Tradition reads only exact meetings, a degree or so at most, so a contact here is rare and worth knowing about. Turn on "✦ fixed stars" under the chart to see all fifteen on the rim.

Your numbers

Numerology, which is its own system and separate from the astrology around it. It reads from the letters of your name and the digits of your birth date, never from your chart or the sky. You can see exactly how each number was worked out, letter by letter.

The tri chart, you, now, and the sky

Three charts in one, reading inside → out: your natal self at the centre (birth), your progressed self in the middle (who you've grown into), and today's transits on the outer ring. Each ring now carries its OWN houses: your natal houses in the centre chart, the progressed chart's houses across the middle band in teal, and the moment's houses across the outer band in pink, each numbered at its inner edge. Where the grids disagree is exactly how far your angles have moved. Spin or play the globe in the chart's corner to move the transit ring through time.

See your progressed chart at age

New to the progressed chart? It uses an old symbolic method: each day after your birth stands for one year of life, so your chart at age thirty is really the sky on the thirtieth day after you were born, nudged gently forward. It tracks inner development, how your character, needs and focus mature over the years, rather than outside events. That is what sets it apart from transits, which are the real planets in today's sky pressing on your chart from the outside. Put simply, transits show what the world is doing to you now, while your progressed chart shows who you have quietly grown into.

Solar arc directions

Solar arc is the predictive sibling of the progressed chart above. It takes the distance your Sun has travelled by progression and moves your whole birth chart forward by that one arc, so the slow planets travel too. Your natal chart is on the inside, your directed chart on the outside, and the lines between the rings are the directions touching you now, read at a tight one degree orb.

What is luck here? ✦

Luck isn't a verdict, and it isn't fate, it's more like weather. Your chart maps where the sky leans in your favour and where it asks more of you. We read that two different ways, so don't be surprised when they disagree:

① Your luck %, the background stretch. Your chart's baked-in fortune (Jupiter, Venus and how your chart holds them) plus the slow tide of the current period. It drifts gently over months and years, a broad climate, not a daily forecast.

② Lucky days, windows of opportunity. The standout days this month, when faster planets make helpful angles to your chart. These are moments to act on. A bright day can fall inside a quieter stretch, and a calm day inside a lucky one, they answer different questions, so we show both.

And never forget: the stars only map the terrain, you walk it. You carry the stardust of the whole universe within you, and you can command it to your will with love and compassion. You are a starchild, the change agent of your own destiny, free to shape your universe however you choose. That is the truest magic of you. Take these as tailwinds, not orders. Go make your own luck. ✦

Astrocartography

Where on Earth your stars fall
🜨 What is astrocartography?

Your birth chart is the sky frozen at one place and one moment. Astrocartography asks a different question: if you'd been born somewhere else, which planets would have been rising, directly overhead, or setting? Those places carry that planet's energy a little louder for you, which is why a city can feel like home before you've unpacked, while somewhere else never quite clicks.

Each of your ten planets traces lines across the globe. Live near one and that planet colours daily life there. Where two lines cross, their energies blend into something stronger, your personal power spots.

The four directions a line can take

Every planet makes four lines, one for each angle of the chart. The angle decides which part of life that planet lights up there.

MC
Midheaven, career & reputation
A vertical line where the planet was highest in the sky. Shapes your work, public image, and calling.
IC
Imum Coeli, home & roots
A vertical line where the planet was directly underfoot. Shapes home, family, and your sense of belonging.
AC
Ascendant, identity
A curved line where the planet was rising in the east. Shapes how you show up and who you become there.
DC
Descendant, relationships
A curved line where the planet was setting in the west. Shapes partnerships and who you draw toward you.

Every planet, line by line
Where to find what you're looking for

Pick the life you're shopping for, and these are YOUR lines to live near, visit, or aim at. Based on classical astrocartography practice: a line is strongest right on it, still strong within about 250 km (150 miles), and fades out by roughly 1,000 km. Where two lines cross, that crossing's latitude matters all the way around the world, in a band about 120 km (75 miles) wide.

Power spots · where two lines meet

Where two of your lines cross, both energies combine. These are your most charged places on Earth.
