The sky
on 31 December 1987.
The sign of each planet that day, calculated from astronomical ephemerides (Paris time). When a planet changes sign during the day, the exact time is given: that’s where the birth time decides.
If this is your birth date
What you are trying to become
You aim far, and you demand a lot of yourself. What you make, you want still standing in ten years. Credit, you give yourself late.
Capricorn begins at the December solstice, the day the Sun turns back. Its symbol is a sea goat: half mountain, half ocean. Saturn rules it.
People think you feel nothing. You have simply already planned next year.
Why?
What you are trying to become, and what you need to be recognised for. In Capricorn, it gets built and proven. You aim far, demand a lot of yourself, and give yourself credit late.
What settles you
Your birth time settles it.
Why?
What settles you and what puts you on alert, before any conscious decision.
What people see first
It takes your birth time and city.
Why?
The first thing people register about you, before they know you.
What draws you
What draws you resembles nobody else. You often begin with friendship, and you keep your freedom in the middle of the relationship.
Aquarius carries water in every drawing, yet it is an air sign: what it pours is ideas. Saturn rules it in the old astrology, Uranus in the new.
What a couple is supposed to be, you would rather decide for yourself.
Why?
What draws you in and what you offer — in love as in taste. In Aquarius, it happens off the rulebook. You step back where others lean in, and it reads as coldness.
What gets you moving
You do not let go. You watch, you wait, you strike once and in the right place. People do not see your decisions coming.
The brightest star of the constellation is Antares: the rival of Mars. Mars rules this sign in the old astrology, Pluto in the new.
Mars rules this sign in the tradition. You know people’s weak point, and you choose whether to use it.
Why?
What you go after, and how you fight when you meet resistance. In Scorpio, it plays out fully and in private. You watch for a long time before committing, then you do not let go. At home. What it governs runs without resistance — the ground where you do not have to force anything.
How you think
You think in plans. You go to what is useful, you say little, and you only talk about what you have checked.
Your humour is dry, and it takes a moment to notice.
Why?
How you think and speak — the pace, the level of detail, what you keep to yourself. In Capricorn, it gets built and proven. You aim far, demand a lot of yourself, and give yourself credit late.
Where you think big
You grow by starting. An opening appeals when nobody has dared yet, and you go before you have the plan.
The zodiac starts here, at the March equinox. Mars rules this sign, and the Sun is exalted in it.
Your luck is your momentum. Your risk is not finishing.
Why?
What you take for granted, and the ground where you let yourself overreach. In Aries, it starts before it is ready. You decide fast, correct on the move, and waiting costs you more than being wrong.
Where you hold firm
You want convictions that hold. You doubt for a long time, you check, you build your own view.
The centre of our galaxy lies in the direction of Sagittarius: look toward the archer, and you are looking at the heart of the Milky Way. Jupiter, the largest planet, rules this sign.
What you believe, you have paid for, and you hold to it.
Why?
What you take seriously, and where you hold yourself to a line. In Sagittarius, it needs a horizon. You take badly to having your ground narrowed, and you leave rather than negotiate.
What dominates
You trust what can be verified — a plan, a number, a proof. Earth's known flip side: change requires a serious reason, never a passing urge.
Why?
We count the ten planets and the rising sign, as in the app.
