Each sign is a season, a symbol, and a temperament — Babylonian astronomy shaped into Greek myth, still in motion today. Pick a sign to read where it comes from, what it actually means, and how it shows up in a full chart.
A zodiac sign is a 30-degree slice of the sky. The Sun appears to travel a full circle against the background stars over a year, and astrologers divide that circle into twelve equal parts — Aries through Pisces. The Sun crosses one slice roughly every month, which is why your “sign” is set by your birthday: it’s the slice the Sun was passing through on the day you were born.
Modern Western astrology uses the tropical zodiac, which is anchored to the seasons rather than the literal star fields. Aries begins at the spring equinox, Cancer at the summer solstice, and so on. That’s why the dates below stay fixed year to year even though the constellations have drifted. The twelve signs are twelve archetypes — twelve recurring ways of being a person — and most people recognise themselves in more than one.
When someone asks your sign, they mean your Sun sign — your core identity and the drive that powers you. But it’s only one placement in a full chart. Your Moon sign rules your emotional life — how you feel, what comforts you, what you need to feel safe. Your rising sign (or ascendant) is the mask you arrive in: how a stranger reads you before they know you. Two people with the same Sun can feel completely different once you know their Moon and rising — which is why sun-sign horoscopes only ever tell part of the story.
Every sign belongs to one of four elements, and the element sets its basic temperament:
Elements describe what a sign is made of; modalities describe how it moves. Each season has one of each:
| Sign | Dates | Element | Modality | Ruler |
|---|---|---|---|---|
| Aries | Mar 21 – Apr 19 | Fire | Cardinal | Mars |
| Taurus | Apr 20 – May 20 | Earth | Fixed | Venus |
| Gemini | May 21 – Jun 20 | Air | Mutable | Mercury |
| Cancer | Jun 21 – Jul 22 | Water | Cardinal | Moon |
| Leo | Jul 23 – Aug 22 | Fire | Fixed | Sun |
| Virgo | Aug 23 – Sep 22 | Earth | Mutable | Mercury |
| Libra | Sep 23 – Oct 22 | Air | Cardinal | Venus |
| Scorpio | Oct 23 – Nov 21 | Water | Fixed | Pluto |
| Sagittarius | Nov 22 – Dec 21 | Fire | Mutable | Jupiter |
| Capricorn | Dec 22 – Jan 19 | Earth | Cardinal | Saturn |
| Aquarius | Jan 20 – Feb 18 | Air | Fixed | Uranus |
| Pisces | Feb 19 – Mar 20 | Water | Mutable | Neptune |
Your Sun sign is a genuinely useful shorthand: it names the drive at your centre and the default way you spend energy. Read well, it’s a mirror — it tends to describe patterns you already half-knew. But it was never meant to carry a whole personality. The reason two Geminis can feel nothing alike is that the rest of the chart — Moon, rising, and the planets across the houses — fills in everything the Sun leaves out. Start with your sign below, then read it as the first page, not the last.
