March Zodiac Sign: Pisces or Aries?
The March zodiac signs are Pisces (approximately March 1–20) and Aries (approximately March 21–31). Birthdays near the change need a calculation using the birth year and time.
The March equinox begins Aries and a new cycle of the tropical zodiac. Its exact timing matters more than a printed March 21 cutoff.

March 20 or 21: Pisces or Aries?
The tropical Sun enters Aries at the March equinox. The equinox is a moment, not an entire calendar day, and its local date can vary. Although many birthday charts use March 21 as the first Aries date, a March 19–21 birthday needs the birth year and time to resolve the sign reliably.
Check your Sun sign with your birth details
Our free birth-chart calculator uses your full birth date, local birth time, and birthplace. If you do not know the time and were born near the sign change, treat the Sun-sign result as uncertain. Choosing a default time cannot settle a boundary birthday.
Calculate your birth chartWhy the March equinox matters
The tropical zodiac measures its twelve equal signs from the March equinox. This is why the transition is tied to a seasonal reference point rather than the outlines of the constellations. March brings spring in the Northern Hemisphere and autumn in the Southern Hemisphere; the tropical sign calculation is the same system in both.
Questions about March birthdays
What zodiac sign is March 17?
March 17 normally falls in Pisces. Its proximity to the equinox does not make it a combined Pisces–Aries sign; a natal Sun occupies one sign at a time.
Is March 25 an Aries birthday?
March 25 is normally Aries in the tropical zodiac. A sidereal chart can use a different sign because it uses a different zodiac reference system. Check which system a calculator uses before comparing results.
