Planets in SignsMars in Gemini: What It Means in a Birth Chart
Mars governs drive, anger and desire, and Gemini is an air sign in mutable mode. Here is what the placement does, its shadow, and the real dates Mars is in Gemini.

The Nine of Swords means dread, anxiety, night. What it means upright and reversed, the four ways readers handle reversals, and the Mars in Gemini attribution behind it.

Pamela Colman Smith drew the Nine of Swords as a figure sitting up in bed with their face in their hands, nine swords mounted on the dark wall behind and carved figures on the bedside. That matters more here than in the Majors. Before 1909 the pip cards of almost every deck showed nothing but an arrangement of cups or coins, and you had to have memorised a meaning to read one. She gave all forty of them a scene, and that single decision is why a beginner can read this deck at all.
The three-in-the-morning version of the problem, which is always the worst and usually the least accurate.
Swords are the thinking suit, and the most uncomfortable of the four. They are about what is being said, decided or avoided rather than what is being felt. The question the card puts to you: How much of this exists at noon.
| If the question is about | The Nine of Swords upright | What to check |
|---|---|---|
| Love | Anxiety about it rather than trouble in it. | Which other suits are on the table |
| Work | Dread that is out of proportion to the meeting. | Whether the position is past, present or advice |
| Money | Sleepless arithmetic. | Whether the surrounding cards agree with it |
The fear losing its grip, or being spoken out loud at last.
Readers disagree about how reversals work, and the disagreement is not minor: the four common methods give four different answers for the same card. Any page that gives you one reversed meaning and does not mention this is simplifying.
| Method | What the reversal means | When it fits best |
|---|---|---|
| Blocked or delayed | The upright meaning, not available yet | The most common method. Works on almost any card |
| The opposite | The reverse of the upright meaning | Cards with a clear opposite, like the Sun or the Ten of Cups |
| Turned inward | The upright meaning, happening privately | The feeling cards, and most of the Cups |
| Too much of it | The upright quality in excess | The strong cards: Strength, the Emperor, the King of Wands |
The Nine of Swords is given the second decan of Gemini, which is the stretch from 10 to 20 degrees of the sign, ruled by Mars. That is not decoration. The thirty-six pip cards from Two to Ten map onto the thirty-six decans in order, and the ruler of each decan comes from the Chaldean sequence counting forward from the first third of Aries. So the card and the placement are describing the same thing twice: Mars in Gemini is the Nine of Swords in a birth chart.
| Field | Value |
|---|---|
| Suit | Swords (Air) |
| Decan | second decan of Gemini |
| Degrees | 10 to 20 degrees of Gemini |
| Ruled by | Mars |
| Reads as | Mars in Gemini |
This is the part that almost no tarot page prints, and it is the part that makes the deck make sense. The seventy-eight cards are not seventy-eight separate ideas. They are four elements, ten numbers, four court ranks and twenty-two Majors, laid over the zodiac in a fixed order. Once you can see the structure you stop needing to memorise anything.
Swords are the thinking suit, and the most uncomfortable of the four. They are about what is being said, decided or avoided rather than what is being felt. Swords are the Air suit and they govern thought, words, conflict and truth. The suit's three signs are Libra, Aquarius, Gemini, in that order: cardinal, fixed, mutable. The Twos, Threes and Fours sit in the first of those, the Fives, Sixes and Sevens in the second, the Eights, Nines and Tens in the third. That is the whole system for the pip cards.
The Eight of Swords. The Eight is stuck. The Nine is awake about it.
Worth knowing, because most pages present card meanings as though they were handed down from antiquity. Playing cards reached Europe in the fourteenth century and the earliest surviving tarot decks were painted in northern Italy in the fifteenth, as a card game. For roughly three hundred years that is all they were. Divination with them is first clearly documented in the late eighteenth century, in France.
The meanings in use today in English are almost entirely the Rider deck's. It was published in London in 1909: Arthur Edward Waite wrote the scheme, Pamela Colman Smith drew all seventy-eight cards, and she was paid a flat fee and went uncredited on the box for most of a century. Her decision to give every pip card a scene rather than a plain arrangement of symbols is the single reason modern tarot works the way it does, because a picture can be read by somebody who has memorised nothing.
Both of them were members of the Hermetic Order of the Golden Dawn, which is where the astrological attributions on this page come from. Those are a genuine system with internal logic, and they are a little over a century old rather than ancient. Saying so costs nothing and it is the difference between a page you can trust on the rest of the detail and a page you cannot.
The deck is the same deck for everybody who picks it up, which is both the appeal and the limit. A birth chart is not shared with anybody: it needs your date, your time and your place. If you do not know your birth time, this covers how to find it.
The Nine of Swords means dread, anxiety, night.
Readers use four different methods for reversals: blocked, opposite, turned inward, or too much of it. The article sets out all four, because they give different answers and no single one is the correct reading.

No. A card describes a situation and asks a question about it. Nothing in the tradition names a date, and nothing in it should stand in for medical, legal or financial advice.
