Final answer:
Astrologically, you may be considered an Aries if you were born from March 21 to April 20, but due to the precession of the equinoxes, the Sun is actually located in the constellation Pisces during this time, not Aries.
Step-by-step explanation:
Despite what astrology traditionally suggests, the Sun is no longer in the constellation associated with your astrological sign due to the precession of the equinoxes. If your astrological sign is Aries, astrology dictates that the Sun would be in the constellation of Aries from March 21 to April 20th. However, because of the phenomenon known as precession, which is the slow westward shift of the constellations along the ecliptic over a period of approximately 26,000 years, the actual position of the Sun during this period has shifted approximately one constellation backwards in the zodiac, putting it in the constellation Pisces for individuals born in that date range today.
One must consider the sign before Aries, which is Pisces, to determine the actual constellation the Sun is in during those dates. What astrology columns generally refer to as your Sun sign is based on where the Sun was located more than 2,000 years ago, not its current location in the sky. Therefore, although you might be an 'Aries' in astrological terms, in astronomical reality, the Sun was in Pisces at the time of your birth if you were born between March 21 and April 20 in the present day.
