The four elements, one sentence each
Fire (Aries, Leo, Sagittarius) is momentum: acting, daring, shining, believing. Earth (Taurus, Virgo, Capricorn) is substance: building, lasting, touching, proving. Air (Gemini, Libra, Aquarius) is connection: thinking, exchanging, linking, understanding. Water (Cancer, Scorpio, Pisces) is feeling: sensing, protecting, merging, transforming. Everyone has all four; the distribution makes the temperament.
The elements read in pairs. Fire and air are the extroverted elements, turned towards the outside and movement; earth and water are the introverted elements, turned towards stability and the inner world. Fire and water are the elements of emotion, air and earth those of reason. A chart that concentrates fire and air lives fast and thinks out loud; an earth and water chart builds in silence and feels deeply.
How this site calculates your dominant element
Planets are not simply counted: a Moon weighs more than a generational Pluto. On your chart page, every point in the sky adds its weight to the element of the sign it occupies. The Sun, the Moon and the Ascendant count 3 points each: the three pillars of personality. Mercury, Venus, Mars and the Midheaven count 2 points: the personal planets and the vocation. Jupiter and Saturn, the social planets, count 1.5 points. Uranus, Neptune and Pluto, which stay years in a sign and speak first of a generation, count 1 point. The North Node, Chiron and Lilith count 0.5 points; the South Node, always opposite the North Node, is not counted a second time.
The total comes to 24.5 points with the birth time (19.5 without the Ascendant and the Midheaven). The element that gathers the most points is your dominant; the dominants section of the result page shows the four bars and the winning mode, right next to the positions table. When two elements are almost tied, you are a mixed temperament, and that is information in itself: read both portraits.
A fictional example: Camille, born in Lyon on 12 May 1990 at 2:30 pm, has the Sun and Mercury in Taurus, the Ascendant in Virgo, and Saturn, Uranus and Neptune in Capricorn. Earth totals 11.5 points, water 5.5, fire 5, air 2.5: a very clear earth temperament, with air lacking. Her Moon in Sagittarius and her Venus in Aries are the only real fire contributions, and it is to them that Camille owes her drive.
And the modes: cardinal, fixed, mutable
The same weights are used to calculate your dominant mode, the second dominant shown on your chart. The cardinal signs (Aries, Cancer, Libra, Capricorn) launch: a cardinal dominant gives initiative, a taste for starting, and the challenge of finishing.
The fixed signs (Taurus, Leo, Scorpio, Aquarius) hold: a fixed dominant gives constancy, loyalty, depth, and the challenge of moving when it is time.
The mutable signs (Gemini, Virgo, Sagittarius, Pisces) adapt: a mutable dominant gives flexibility, curiosity, a sense of transition, and the challenge of choosing. Cross element and mode: fixed earth does not live like mutable earth.
