Quick Answer
March has two zodiac signs. Pisces covers February 19 to March 20, and Aries covers March 21 to April 19. The spring equinox, falling on March 20 or 21 each year, marks the exact boundary. If you were born March 1 to 19, you are Pisces. March 21 onward is Aries. For March 20, your birth time determines the sign.
Key Takeaways
- Two signs in March: Pisces governs March 1 to 20 and Aries governs March 21 to 31, with the exact boundary set by the spring equinox each year.
- The equinox matters: March 20 or 21 is the vernal equinox, when the Sun enters 0 degrees Aries: the beginning of the astrological year in Western tradition.
- March Pisces: Water sign ruled by Neptune, the last sign of the zodiac, associated with intuition, empathy, and creative depth.
- March Aries: Fire sign ruled by Mars, the first sign of the zodiac, associated with initiation, boldness, and pioneering energy.
- Check your time: If you were born on March 20 or 21, only a birth chart with your exact birth time and location will confirm which sign you are.

March's Two Zodiac Signs at a Glance
If you are asking what zodiac sign is March, the answer is: it depends on which part of March. The month is divided between two very different signs, and the line between them is not arbitrary. It falls on the spring equinox, one of the most astronomically and symbolically significant moments of the year.
Pisces governs from approximately February 19 through March 20. Aries begins on approximately March 21 and runs through April 19. The Sun's entry into Aries is the start of the astrological year in Western tradition, making the late March period one of the most cosmologically loaded transitions in the zodiac cycle.
For most people born in March, the sign is clear: born March 1 through 19, you are Pisces; born March 22 through 31, you are Aries. For those born on March 20 or 21, the exact birth time in your birth year matters, and a birth chart calculation will confirm it precisely.
The Spring Equinox and the Astrological New Year
The spring equinox, occurring on or around March 20 each year in the Northern Hemisphere, is the moment when day and night are equal in length and the Sun crosses the celestial equator moving northward. In astronomical terms, this is the vernal point. In astrological terms, it is 0 degrees Aries: the origin point of the entire zodiac.
Why Aries Begins the Zodiac
Western astrology is structured around the tropical zodiac, which begins at 0 degrees Aries, defined as the spring equinox point. This was not always the case in ancient astronomy: before the precession of equinoxes shifted the relationship between the tropical and sidereal zodiacs, the Sun was actually in the constellation Aries at the spring equinox. Today the equinox point falls in the constellation Pisces, but the tropical zodiac retains Aries at 0 degrees as the symbolic starting point. This distinction is why Western and Vedic (sidereal) astrology give different sign placements for the same birthdate. In Western tradition, the spring equinox remains the zero point around which the entire system is organized, making the Sun's entry into Aries the astrological new year regardless of the calendar date.
This matters for March birthdays because the equinox defines the Pisces-Aries boundary with precision. The Sun is not in Aries because March 21 is on a calendar. It is in Aries because the equinox moment has been reached, and that moment varies slightly each year based on the precise geometry of Earth's orbit.
March Pisces: The Last Sign and Its Gifts
Pisces is the twelfth and final sign of the Western zodiac, a mutable water sign spanning from approximately February 19 to March 20. It is ruled by Neptune in modern astrology and by Jupiter in the traditional pre-telescopic system. This dual rulership carries meaning: Neptune governs dissolution, the unconscious, and spiritual receptivity, while Jupiter governs expansion, wisdom, and connection to something larger than the self.
The symbol of Pisces is two fish swimming in opposite directions, bound together by a cord. This image captures the essential Piscean tension: pulled between the material world and the spiritual, between defined identity and the dissolution of boundaries. The fish swim in circles, each containing the seed of the other's direction. It is a symbol of paradox held in balance.
Pisces as the End and the Beginning
In esoteric astrology, Pisces is understood as the sign of dissolution: not destruction, but the necessary release of form before new form can arise. As the final sign, Pisces contains residue from all eleven signs that preceded it, which is one reason the sign is associated with deep empathy and an unusual ability to feel what others feel. The Piscean is, in a sense, carrying the accumulated experience of the entire zodiac cycle. The mutable quality of the sign (shared by Gemini, Virgo, and Sagittarius) indicates adaptability and the capacity to shift, to be shaped by the environment rather than imposing form upon it. Pisces ends the cycle so that Aries can begin it again.
March Pisces are those born in the final weeks of the zodiac year. In practical terms, Pisces is associated with strong intuitive and emotional intelligence, a natural affinity for creative work (particularly music, visual art, and poetry), compassion that can extend to the point of self-neglect, and a sometimes blurred relationship with firm boundaries. The challenge of the sign is discernment: knowing which feelings are yours and which belong to the surrounding environment.
Notable March Pisces: Albert Einstein, born March 14, 1879. His willingness to hold contradictory ideas simultaneously, his famous thought experiments, and his reported comment that imagination is more important than knowledge all reflect the Piscean capacity to work with intuition and paradox at the highest levels.

March Aries: The Ram at Its Most Direct
Aries is the first sign of the Western zodiac, a Cardinal fire sign spanning from approximately March 21 to April 19. It is ruled by Mars, the planet of action, drive, courage, and directed force. The symbol of Aries is the ram: a creature associated with forward motion, charging headlong into what it encounters, and leading from the front.
As a Cardinal sign, Aries initiates. Cardinal signs (Aries, Cancer, Libra, Capricorn) begin each season and carry an energy of starting rather than sustaining or completing. Aries begins the astrological year, and this quality of first-ness is central to the sign's character. Aries is the energy of the absolute beginning: the first impulse, the clean slate, the moment before complication sets in.
March Aries, those born in the final ten days of March, are the earliest Aries of the year. Early degrees of any sign carry the most concentrated expression of that sign's essential quality. A March Aries is Aries at its most archetypal: bold, direct, impatient with delay, quick to act and quick to move on. The gift is initiative; the challenge is sustaining interest and energy once the novelty of beginning has passed.
Notable March Aries: Vincent van Gogh, born March 30, 1853. His explosive creative output, his refusal to compromise his artistic vision regardless of reception, and his complete commitment to each canvas he worked on reflect Aries Mars energy applied to creative work with uncommon intensity.

The Pisces-Aries Cusp: Rebirth at the Boundary
The days around March 19 to 21 are sometimes called the cusp of rebirth in popular astrology. The name is apt even if the technical framework is imprecise. The transition from Pisces to Aries is the most structurally significant cusp in the entire zodiac cycle: it is the movement from the last sign to the first, from dissolution to initiation, from the end of one cycle to the absolute beginning of the next.
Spiritually, this cusp maps onto some of the oldest mythological narratives humans have. Death and resurrection. The seed in the dark earth breaking open to send the first shoot upward. The moment before dawn when the darkness is deepest. Pisces carries the completed experience of all that came before. Aries arrives with none of that weight, only the pure impulse of beginning.
For people born near this boundary who relate to both signs, this is the astrological context: you stand at the end and the beginning simultaneously. Whether that manifests as unusual creative range, a tension between withdrawal and assertion, or an innate sense of cycling between phases rather than holding a steady state, the cusp position is one of genuine archetypal power in the symbolic framework of the zodiac.
Practice: Working With Your March Sign's Season
Regardless of whether you are a March Pisces or March Aries, the weeks around the spring equinox offer an annual reset point that aligns with your birth energy. For March Pisces: the days just before the equinox are your natural completion time. Identify one thing you have been carrying that is ready to be released. It may be a relationship pattern, a creative project stalled for the wrong reasons, or a way of thinking about yourself that no longer fits. The end of the Pisces season is designed for release. For March Aries: the equinox is your energetic ignition point. Identify the single most important thing you want to initiate in the next three months. Write it as a declaration, not a wish. "I am beginning X." The Aries season rewards those who begin cleanly and with commitment.
How to Find Your Exact March Sign
For birthdays between March 1 and 19, the sign is Pisces without question. For birthdays between March 22 and 31, the sign is Aries. The only ambiguous dates are March 20 and 21, when the equinox transition may or may not have occurred at the time of your birth.
To find your exact sign for these dates, use a birth chart calculator with your birth year, time, and location. Free tools at Astro.com or similar sites will compute the Sun's exact degree and sign at your birth moment. Look at the Sun's position and note whether it shows late Pisces (28 or 29 degrees Pisces) or early Aries (0 or 1 degree Aries).
If you were born in a time or place where your birth time was not recorded, or if your birth certificate does not include a time, you can research the spring equinox time for your birth year. This information is publicly documented by astronomical records. If the equinox fell in the afternoon and you were born at night, you were born into Aries. If the equinox had not yet occurred when you were born, you were born into late Pisces.

The Month That Holds Two Worlds
March is the only month that contains both the end of the zodiac year and its beginning. In Pisces, the wheel completes: everything experienced, learned, and accumulated over the previous eleven signs settles into the still waters of the last sign. In Aries, the wheel starts again: the first fire, the first impulse, the absolute present tense of beginning. To be born in March is to arrive at a threshold. Whether you are the one completing or the one starting depends on which side of the equinox you were born on. Either way, you entered a world in the act of turning.
Frequently Asked Questions
What zodiac sign is March?
March contains two zodiac signs: Pisces and Aries. Pisces runs from approximately February 19 to March 20, covering the first three weeks of March. Aries begins on approximately March 21 and runs through April 19, covering the last ten days of March. The spring equinox, when the Sun enters 0 degrees Aries, marks the boundary between the two signs and varies slightly each year.
What sign is March 20?
March 20 is typically the last day of Pisces, but the exact cutoff depends on the year and your birth time. The Sun enters Aries on the spring equinox, which falls on March 20 or 21. If you were born on March 20 before the exact equinox time in your birth year, you are Pisces. If born after it, you are Aries. Use a birth chart calculator with your time and place of birth to confirm.
What is the difference between March Pisces and March Aries?
March Pisces (born March 1 to 20) is a mutable water sign ruled by Neptune, associated with intuition, empathy, creativity, and emotional depth. March Aries (born March 21 to 31) is a Cardinal fire sign ruled by Mars, associated with initiation, bold action, directness, and pioneering energy. The transition from Pisces to Aries at the equinox represents a shift from dissolution and receptivity to assertion and new beginnings.
Is March 21 an Aries or Pisces?
March 21 is almost always Aries. The spring equinox, when the Sun enters Aries, typically falls on March 20 or 21, and by March 21 the Sun has nearly always already crossed into Aries. However, for births very early in the day on March 21 in certain years, Pisces remains possible. A birth chart with your exact birth time and location will confirm your sign definitively.
What is the Pisces-Aries cusp?
The Pisces-Aries cusp (around March 19 to 21) is sometimes called the cusp of rebirth in popular astrology. It describes people born near the boundary between the two signs who may relate to characteristics of both: Piscean sensitivity and intuition combined with Aries boldness and initiative. Technically, the Sun occupies exactly one sign at any given moment, but other planets in a birth chart near this boundary can reinforce qualities of both signs.
