In the Lahiri sidereal zodiac, the Sun enters Pisces on approximately March 14 and leaves on approximately April 13. This corresponds to most of what tropical astrology calls Aries. If you were born between roughly March 14 and April 13, your sidereal Sun sign is Pisces. This period includes the March equinox (around March 20 or 21), which is 0° Aries in the tropical zodiac but falls inside sidereal Pisces because sidereal Aries does not begin until approximately April 14.
Why does sidereal Pisces start on March 14?
The fact that the March equinox now falls within sidereal Pisces rather than Aries is sometimes described as evidence that we are in the 'Age of Pisces.' Ages are defined by which sidereal constellation the March equinox precesses through over roughly 2,160 years. The Lahiri sidereal zodiac does not use constellation boundaries (the actual Pisces constellation is much larger than 30 degrees), but the association is often made in popular discussion.
What if you were born on the cusp?
People born in the last week of tropical Pisces (roughly March 14 to March 20) are in the cusp zone. Your tropical Sun is Pisces but your sidereal Sun may also be Pisces depending on the year. People born in the first week of tropical Aries (March 20 to approximately March 24) will also have a sidereal Sun in Pisces, not Aries.
