March 21 marks the seasonal shift into Aries in most traditional calendars, yet for many born on this date the question is are they Pisces. Astrological interpretations vary by system, so the answer depends on which zodiac framework you follow.
For tropical astrology users, the Sun remains in Pisces through most of March 21, placing this birthday squarely in the Pisces season. For sidereal systems, the Sun may already have moved into Aries, changing the sign association.
