Pisces Dates, Traits & Compatibility (Feb 19 to Mar 20)

Pisces illustration

Pisces runs February 19 to March 20, closing out the astrological year, and its symbol carries a small, specific detail worth knowing: the two fish aren’t just swimming side by side, they’re tied together by their tails so they don’t lose each other.

Dates, element, and modality

  • Dates: February 19 to March 20 (inclusive)
  • Element: Water
  • Modality: Mutable
  • Symbol: Two Fish, drawn tied together by a cord (♓)

Mutable signs close out a season, and Pisces wraps up winter right as it dissolves into spring, arguably the most transitional stretch on the entire calendar. Mutable Water is where astrology gets Pisces’s reputation for fluid, hard-to-pin-down boundaries: emotional depth (Water) that doesn’t hold one fixed shape (Mutable), unlike Scorpio’s Fixed Water or Cancer’s Cardinal Water.

The myth behind the symbol

The story behind Pisces involves Aphrodite and her son Eros fleeing the monster Typhon, the largest and fiercest creature born to Gaia, along the banks of the Euphrates River. Versions differ on the exact mechanics: some say the two gods leapt into the river and transformed themselves into fish, others say two fish appeared and carried them to safety. What every version agrees on is the detail that gives the constellation its distinctive shape: to avoid being separated in the chaos, Aphrodite and Eros tied their tails together with a cord, and the star marking that knot still sits between the two fish in the sky today. A separate, older Syrian myth ties the same fish to Aphrodite’s own birth, crediting them with nudging the egg she hatched from safely to shore.

Ruling planet

Classical astrology assigns Pisces’s rulership to Jupiter, the same planet that rules Sagittarius, though Pisces channels it into imagination and empathy rather than Sagittarius’s outward-bound optimism. After Neptune’s discovery in 1846, modern astrologers added Neptune, the planet named for the sea god, as a fitting second ruler for a Water sign built around dissolving boundaries. Neither Jupiter nor Neptune has a physical connection to the constellation Pisces; both rulerships are symbolic conventions layered on at different points in astrology’s history, not astronomical facts.

Personality lore

Mutable Water combines emotional depth with a comfort in shifting shape, a distinct mix from Scorpio’s Fixed Water (intensity that holds its ground) or Cancer’s Cardinal Water (protective and quick to act). That combination is where Pisces gets its lore as empathetic, imaginative, and comfortable with fluid boundaries between itself and others, more prone to absorbing other people’s moods than defending against them. It’s a specific trait profile built from element-modality logic, not a vague “dreamy” label.

Compatibility

Charts commonly pair Pisces with Cancer and Scorpio, the other two Water signs, on the theory that shared-element signs understand each other’s emotional depth without translation. Earth signs, especially Taurus and Capricorn, are the other classic pairing, since Water is said to nourish Earth’s steady growth. As always, treat compatibility lists as folklore that varies by tradition.

Tropical zodiac vs the night sky

Pisces’s dates follow the tropical zodiac, a seasonal system rather than a live map of the stars, and this is actually the sign where the mismatch matters most for astronomy watchers: the vernal equinox, the astronomical marker for the start of spring, technically falls within the modern boundaries of the constellation Pisces today, even though tropical astrology still treats Aries as the “first” sign for calendar reasons dating back roughly two thousand years. Worth stating clearly, once: none of this is science. Astronomy tracks the measurable positions of stars and planets; astrology assigns cultural meaning to birth dates through an older symbolic framework. Precession, Earth’s roughly 26,000-year axial wobble, is the reason for that mismatch, and NASA’s explainers on this topic also mention Ophiuchus, a 13th constellation on the ecliptic that tropical astrology never assigned a sign to. If you were born right around February 19, the Aquarius page is worth a look, since some charts shift that cusp by a day.

Common questions

When is Pisces?

On this site, Pisces runs February 19 to March 20 in the tropical (season-based) Western zodiac, the last sign of the astrological year. Some charts shift the cusp by a day depending on the year.

What myth explains the two Pisces fish?

Aphrodite and her son Eros fleeing the monster Typhon along the Euphrates River. In most versions they leapt into the water and transformed into fish to escape, or two fish carried them to safety, and to avoid losing each other they tied their tails together with a cord, the knot still marked by a star between the two fish in the constellation.

What are Pisces's element, modality, and ruling planet?

Pisces is a Water sign with Mutable modality. Classical astrology assigns Jupiter as its ruler; modern astrology, after Neptune's 1846 discovery, added Neptune as a fitting co-ruler for a water sign. Neither planet has a physical connection to the constellation.

Which signs are traditionally compatible with Pisces?

Sun-sign astrology usually pairs Pisces with fellow Water signs Cancer and Scorpio, on the logic that same-element signs share emotional depth, and with Earth signs like Taurus and Capricorn, since Water is said to nourish Earth's growth. Other traditions weigh it differently.

Why might my star sign differ from tonight's constellation?

Tropical astrology divides the year into 12 equal 30-degree slices anchored to the equinoxes and solstices, not to where constellations currently sit. Precession has shifted the constellations out of sync with those slices over roughly 26,000 years, which is why NASA's explainers note the sky and the sun-sign calendar no longer line up.
