The sky
on 4 January 1921.
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
You feel everything, and you show almost nothing. What touched you stays deep down, long after others have forgotten.
The brightest star of the constellation is Antares: the rival of Mars. Mars rules this sign in the old astrology, Pluto in the new.
The Moon is in its fall in this sign. What settles you is knowing the truth, even a bad one.
Why?
What settles you and what puts you on alert, before any conscious decision. In Scorpio, it plays out fully and in private. You watch for a long time before committing, then you do not let go. Opposite its exaltation: weakened ground. Not a sentence — a place where you learn what others take for granted.
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 move because you are asked to. An instruction makes you want to do the opposite, and you fight better for a cause than for yourself.
Your anger stays in your head: you explain, and it hurts more than a shout.
Why?
What you go after, and how you fight when you meet resistance. In Aquarius, it happens off the rulebook. You step back where others lean in, and it reads as coldness.
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 through detail. A trade learned thoroughly, a tool mastered, a method that works.
Mercury rules this sign and is exalted in it, a case unique in the zodiac. The brightest star is Spica, the ear of wheat.
Jupiter is in detriment in this sign: better sometimes stops you seeing good.
Why?
What you take for granted, and the ground where you let yourself overreach. In Virgo, it gets settled in the details. You spot what is off before looking for it, and you say so. Opposite its home: adverse ground. What it governs takes deliberate effort — and is worth working for exactly that reason. Retrograde at your birth: seen from Earth, the planet was moving backwards. What it governs turns inward first, and shows later than it does in other people.
Where you hold firm
You let nothing pass, especially in yourself. Work done well reassures you, and a flaw can keep you awake.
Your rigour is your strength, as long as you know when to stop.
Why?
What you take seriously, and where you hold yourself to a line. In Virgo, it gets settled in the details. You spot what is off before looking for it, and you say so.
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.
