Fixed Signs in Astrology

Astrology has four fixed signs: Taurus, Leo, Scorpio, and Aquarius. In the Northern Hemisphere each one is the middle sign of a season: Taurus of spring, Leo of summer, Scorpio of autumn, and Aquarius of winter. The tradition reads the fixed modality as steady, the group that holds on to a direction once it has one.

Fixed signs at a glance

• Signs (usual dates, ET): Taurus, Earth (April 19 – May 20); Leo, Fire (July 22 – August 22); Scorpio, Water (October 23 – November 21); Aquarius, Air (January 19 – February 18)
• Position in the season: middle sign of each season in the Northern Hemisphere: Taurus in spring, Leo in summer, Scorpio in autumn, Aquarius in winter
• Opposite pairs within the modality: Taurus – Scorpio; Leo – Aquarius
• Rulers: Venus (Taurus); Sun (Leo); Pluto in modern astrology, Mars traditionally (Scorpio); Uranus in modern astrology, Saturn traditionally (Aquarius)

Taurus is fixed Earth, ruled by Venus, and the middle sign of spring in the Northern Hemisphere (of autumn south of the equator). In astrology Earth belongs to the material world, and in a fixed sign that becomes steadiness about material things: what is owned, used and kept. Picture the person who finds a pen they like and buys it by the box, so the choice never has to be made again. Dates and traits are on the Taurus page.

Leo, fixed Fire under the Sun's rulership, is the middle sign of summer in the Northern Hemisphere (of winter south of the equator). Fire is one of the two active, expressive elements, so the tradition reads fixed Fire as steadiness that shows on the outside, kept where other people can see it and set their own plans by it. Think of the house whose holiday lights go up on the same weekend every year, so the whole street knows the season has started. The sign is profiled under Leo.

Scorpio is fixed Water, ruled by Pluto in modern astrology and by Mars traditionally, and the middle sign of autumn in the Northern Hemisphere (of spring south of the equator). Like Earth, Water is a receptive element, and astrologers read fixed Water as steadiness that works quietly, with little display. Think of the person who has practiced the same piano piece every evening for a year and has not yet played it for anyone. For the sign itself, see Scorpio.

Aquarius, the fixed Air sign, has Uranus as its modern ruler and Saturn as its traditional one, and it is the middle sign of winter in the Northern Hemisphere (of summer south of the equator). Air shares Fire's active polarity, and the tradition reads fixed Air as steadiness carried on in company. Think of the Thursday trivia team that has kept the same name, and the same four players, since the night it formed. Its own guide is Aquarius.

Modality, in astrology, is a sign's position in the season it belongs to. In the Northern Hemisphere, spring holds Aries, Taurus, and Gemini; summer holds Cancer, Leo, and Virgo; autumn holds Libra, Scorpio, and Sagittarius; winter holds Capricorn, Aquarius, and Pisces. In each of those trios the fixed sign is the second of three. South of the equator the season names are reversed, so Scorpio counts as a spring sign there and Taurus as an autumn one, yet each still sits in the middle of its season and stays fixed.

The tradition reads the group as steady, and since each element turns up once among the four, that steadiness takes four forms. On the wheel the fixed signs make two opposite pairs, Taurus across from Scorpio and Leo across from Aquarius.

The other two modalities sit on either side of the fixed one. Cardinal signs open each season, and astrologers read them as the group that starts things. Mutable signs close it, and the tradition reads them as flexible.

In relationships, astrologers associate fixed placements with constancy: the same close friends across decades, and promises that get kept. The tradition also pictures the downside: in a quarrel a fixed sign may simply refuse to move, even after the other person has come halfway. The element shapes how the constancy shows: more openly in Leo and Aquarius, the active pair, and more privately in Taurus and Scorpio, the receptive pair. Astrologers read this from more than the Sun: a chart's Moon, Ascendant, and planets each fall in a fixed, cardinal, or mutable sign too.

At work, the fixed modality is read as follow-through: the long assignment seen to the last page, the system kept running after the team that built it has moved on. Take an example chart with the Sun in Sagittarius, the Moon in Leo, and Scorpio rising. The Sun is mutable, but the Moon and the Ascendant are both fixed, so an astrologer might describe someone who takes on varied work easily and, once a task is theirs, is hard to pull away from it. Astrology is an interpretive tradition, not a scientifically validated method, so weigh a reading like this against what you already know about yourself.

FAQ

What are the fixed signs? Taurus, Leo, Scorpio, and Aquarius: one Earth, one Fire, one Water, and one Air sign. Each is the middle sign of its season, and together they form one of the three quadruplicities, the groups of four signs that share a modality.

What does it mean to be a fixed sign? Most people who say it mean their Sun was in Taurus, Leo, Scorpio, or Aquarius at birth, the one placement simplified, popular sun-sign astrology works from. The tradition reads that as a fixed core, steady and slow to change course, with the sign's element setting its tone. A birth chart can also hold fixed placements when the Sun is somewhere else. How the fixed group fits beside the cardinal and mutable signs is shown on all three modalities.
