02 Pisces field guide
Pisces dates—and where the boundary really is.
Pisces dates are usually listed as February 19 – March 20. Astronomically, a Pisces sun sign means the tropical Sun was between 330° and just under 360° of zodiac longitude at birth. On a boundary date, year, time, and location can change the result, so calculate the chart instead of relying on a generic date table.

When is Pisces season?
Pisces dates are usually listed as February 19 – March 20. Astronomically, a Pisces sun sign means the tropical Sun was between 330° and just under 360° of zodiac longitude at birth. On a boundary date, year, time, and location can change the result, so calculate the chart instead of relying on a generic date table.
The Sun does not enter Pisces at midnight on the same civil date everywhere. The boundary is an astronomical moment, while a date table is a simplified calendar guide.
One sign equals thirty degrees
Western tropical astrology divides the ecliptic into twelve equal 30-degree signs beginning at 0° Aries. Pisces occupies 330° through just under 360° in that coordinate system.
That is different from a constellation boundary. MyMysticDay uses the tropical zodiac consistently across its calculators and interpretations.

Degrees inside Pisces
The first third covers 0°–9°59′ Pisces, the middle third 10°–19°59′, and the final third 20°–29°59′. Traditional decan systems add nuance, but the exact degree comes from a calculated chart—not from dividing a generic date range evenly.
A late-degree Pisces Sun is still a Pisces Sun. Being near Aries does not blend two sun signs automatically; other placements may explain why both descriptions feel familiar.
What “on the cusp” should mean
If a birthday falls near the transition from Aquarius to Pisces, or from Pisces to Aries, enter the birth year, time, and location in a natal chart calculator. Those details convert the civil birth time to one instant and calculate the Sun’s actual longitude.
If the birth time is unknown, the Sun can usually still be identified; only on a narrow boundary window may the time decide the answer.
Pisces elsewhere in the chart
The sign is a method. The planet decides what it is applied to.
Most people meet Pisces as a Sun sign. In a full chart it can also style emotion, thinking, attraction, drive, growth, or discipline — and each of those reads differently.
Add the missing dimensions
Your Sun sign is one coordinate. Draw the map.
A birth chart adds Moon, rising sign, planets, houses, aspects, and exact degrees—calculated from one birth moment instead of guessed from a date range.
- Pisces Sun February 19 – March 20
- Moon sign Changes every 2½ days
- Rising sign Changes every 2 hours
- Houses & aspects From your exact birth minute
