Decan 1 · 1–10°
Sub-ruler: Neptune
Double Neptune — the dreamiest and most impressionable.
Roughly the first ten days of the sign.
February 19 – March 20 · Water · Mutable · ruled by Neptune (traditionally Jupiter)
Empathy, imagination and porous boundaries.
Calculated, not approximated
Every other site prints "February 19 – March 20" with a note that dates "may vary by a day". They vary because the Sun crosses the boundary at a specific moment, and that moment shifts each year — but it is not unknowable.
The figures above are computed: the Sun enters Pisces when its ecliptic longitude reaches 330°, and that crossing is found to the minute. If you were born near a boundary, this is the answer you actually needed.
Rarely covered
Each sign divides into three ten-degree segments, and each has its own sub-ruler. Two people can both be Pisces and read as noticeably different because they fall in different decans — roughly, early, middle or late in the sign.
Decan 1 · 1–10°
Double Neptune — the dreamiest and most impressionable.
Roughly the first ten days of the sign.
Decan 2 · 11–20°
Emotionally attuned and nurturing. Feels for everyone.
Roughly the middle ten days of the sign.
Decan 3 · 21–30°
Deeper and more transformative. Compassion with steel in it.
Roughly the last ten days of the sign.
Feels what other people feel, often before they do. Creative without forcing it.
Absorbs moods indiscriminately and retreats into fantasy when reality gets loud.
Pisces is the one mutable water sign — and that pairing is the whole explanation. The element sets temperament: water signs read the room before anyone speaks. The modality decides what happens when circumstances change: mutable signs adapt to it.
There are exactly twelve combinations of four elements and three modalities, and each is occupied by one sign. That is why no two signs are interchangeable, and why Pisces cannot be swapped for the other water signs without changing the meaning.
Gentle, imaginative and porous. Absorbs the mood of whoever he is with.
Empathic and romantic, prone to loving a version of someone rather than the person.
Worth saying plainly: nothing in astrology assigns different meanings to a sign by gender. These descriptions reflect how the traits are conventionally written about, not a separate system — and plenty of people will recognise themselves in the other one.
Devoted and idealising. Prone to loving a version of someone rather than the person.
The one who understands without being told, and disappears when overwhelmed.
Excels in creative and caring work. Needs structure supplied by someone else.
Art, music, care work, therapy, anything requiring empathy or imagination.
Vague about it. Generous to a fault and reluctant to name a price.
Dreamy, sensitive and easily overwhelmed. Needs gentle structure supplied from outside.
Compassionate and imaginative. Struggles with boundaries and consistency.
Feet and lymphatic system — Pisces rules them, the last sign governing the last part of the body.
Ranked by the angle between the two signs on the wheel — the same geometry astrology uses for aspects. Signs 120° apart share an element and form a trine; 90° apart is a square. Nothing here is a matter of opinion.

|---|---|---|---|---|
| ♋ Cancer | Trine | 120° | 88% | Water |
| ♏ Scorpio | Trine | 120° | 88% | Water |
| ♉ Taurus | Sextile | 60° | 82% | Earth |

Lists like this are the weakest evidence in astrology and the most quoted. With roughly a twelfth of all people in any sign, every sign has impressive members — picking four of them proves nothing. Read it as trivia, not as support.
February 19 – March 20 as usually published. In 2026 specifically the Sun enters on 18 February pm28 15:47 UTC and leaves on 20 March pm31 14:38 UTC.
By aspect, Cancer, Scorpio, Taurus. Those sit at the easiest angles on the wheel — but sun signs are one factor of many, and a difficult angle describes friction rather than failure.
A ten-degree third of the sign with its own sub-ruler: Neptune, Moon, Pluto. It is why two people of the same sign born three weeks apart can read quite differently.

Not in the system itself — astrology assigns no gendered meaning to a sign. The separate descriptions above reflect convention in how signs are written about, nothing more.
