The twelve zodiac signs and how they match Dates measured, compatibility drawn from the zodiac's own geometry.
There are twelve zodiac signs, each a 30 degree slice of the Sun's yearly path: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Your Sun sign is the slice the Sun stood in when you were born. Signs of the same element sit 120 degrees apart and get on most easily; signs 90 degrees apart meet with friction.

The angles
What each angle between two signs means
Five of these descriptions are printed from the compatibility chapter of the Skyprint reading, where the same angles are measured between every planet in two charts.
Easy flow
Trine, 120°
A trine flows without effort. It costs nothing to access, which is its gift and its risk: the easy things between two people are also the ones most often taken for granted.
Open door
Sextile, 60°
A sextile is a door left open between you rather than a room you already share. It is there and it is real, but it only does anything if one of you actually reaches for it.
Opposites attract
Opposition, 180°
An opposition pulls in two directions at once. Handled well it balances you, each supplying what the other lacks. Handled poorly it becomes a tug of war neither of you wins.
Mirror
Same sign, 0°
A conjunction means the two placements sit together and act as one shared force between you. It is effortless, which also makes it easy to lose track of where one of you ends and the other begins.
Neighbours
Semi-sextile, 30°
Neighbouring signs share a border and little else: a different element and a different mode. There is curiosity between them, and each has to learn the other's language.
Adjustment
Quincunx, 150°
A quincunx joins two signs with nothing in common, neither element nor mode nor rhythm. It asks both people to keep adjusting, and couples who manage it find it keeps them curious.
Friction
Square, 90°
A square is real friction, and real friction is where growth happens. It rarely feels good at first. Most long relationships name their square as the thing they value most once they have worked it through.
Elements and modes
Fire, earth, air and water
Fire
Aries, Leo and Sagittarius
Fire signs act. They are warm, direct and quick to start, and they bring energy to the people around them. The risk is burning out, or burning through other people's patience.
Earth
Earth signs build. They trust what they can touch and measure, and they are loyal, practical and patient. The risk is staying with what already works for too long.
Air
Air signs think and connect. They live in ideas, talk and relationships, and they see a question from several sides. The risk is living in their heads.
Each element has one sign in each mode. Cardinal signs (Aries, Cancer, Libra, Capricorn) start things, and each opens a season. Fixed signs (Taurus, Leo, Scorpio, Aquarius) hold and keep. Mutable signs (Gemini, Virgo, Sagittarius, Pisces) adapt, and each closes a season.
Your whole sky
Your sign is one placement in a whole chart
The Sun sign comes from your birth date. The Moon changes sign every two to three days and the rising sign roughly every two hours, so your chart is far more specific than your sign. Your birth date, time and place draw it, computed to the arcminute.

Questions
Zodiac sign questions, answered
How many zodiac signs are there?
Twelve: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Each covers 30 degrees of the ecliptic, the Sun's path across the sky over a year, counted from the March equinox.
How do I find my zodiac sign?
Your Sun sign is set by your date of birth. If you were born near the start or end of a sign, the exact moment matters, because the Sun changes sign on a slightly different day and hour each year. Enter your birth date, time and place on the Skyprint birth chart to see your exact Sun, Moon and rising sign, free.
Which zodiac signs are most compatible?
By the geometry of the zodiac, signs of the same element sit 120 degrees apart, in trine, and get on most easily. Signs 60 degrees apart, fire with air and earth with water, come next. Signs 90 degrees apart meet with the most friction. A real match depends on both full charts.
What is the difference between a Sun, Moon and rising sign?
The Sun sign describes your core self and direction, the Moon sign what you need to feel safe, and the rising sign how you come across to others. The Sun sign comes from your birth date, the Moon needs the date and roughly the time, and the rising sign needs the exact time and place of birth.
How this page was made: Skyprint is built and edited by Khalil Yazouri. The text was drafted with AI assistance. The sign dates were measured with Astronomy Engine for every year from 1940 to 2030, the compatibility follows the angles between the signs, and the sample pages are printed word for word from the reading's own library.
