Born on March 20
A cusp birthday. In most years the Sun crosses from Pisces into Aries during March 20, so people born this day are one or the other depending on the hour. At noon UTC it's Pisces in 63% of years.
Pisces or Aries? Check your year
The Sun's entry into Aries shifts by a few hours from year to year. Find your birth year, convert your birth time to UTC, and compare: born before the time shown, you're Pisces; after it, Aries. Years missing from the list had the crossing on a neighbouring day (the Sun was in one sign for the whole of March 20).

Your sign: Pisces (or Aries)
The mutable water sign that dissolves boundaries and feels what others don't even notice.
A Pisces Sun is built around empathy and imagination. You feel things that haven't been said. You read the room, the energy, the unspoken — and you're often right. This intuition is real, and it makes you formidable in any creative or healing field that rewards seeing what's beneath the surface.

Your decan: the third decan of Pisces
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 20–30 of Pisces belong to Mars: your drive — how you take action, what makes you angry, and what you fight for. Read it as Pisces with a Mars accent — the water core is unchanged, the emphasis moves.
Ten of Cups
Harmony · Family joy · Fulfilment. The card assigned to this ten-degree slice of the zodiac — a birthday card in the same sense a sun sign is a birthday sign: one lens on the date, not a verdict.

The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Pisceans born on March 20 in different years have different Moons; your rising sign changes every two hours and needs a birth time and place. Those two carry most of what people mean by "personality" in a chart.

Common questions
Is March 20 Pisces or Aries?
Both are possible. On March 20 the Sun moves from Pisces into Aries in most years, at a time that ranges from 02:16 UTC to 23:20 UTC UTC across 1980–2030 (in some years the crossing falls on the neighbouring day). Convert your birth time to UTC and compare it with the crossing for your year in the table above — before it you're Pisces, after it Aries.
What zodiac sign is March 20?
March 20 is a cusp day between Pisces and Aries; at noon UTC it falls in Pisces in 63% of years between 1980 and 2030. Your birth year and hour decide it.
What decan is March 20?
The third decan of Pisces (20°–30°), sub-ruled by Mars. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here your drive — how you take action, what makes you angry, and what you fight for.
What tarot card is March 20?
In the Golden Dawn system each decan has a minor arcana card: for the third decan of Pisces it is the Ten of Cups (harmony, family joy, fulfilment). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on March 20 have the same chart?
No. They share the Sun in Pisces or Aries, but the Moon changes sign every two to three days, the rising sign every two hours, and the outer planets by year. Two people born March 20 in different years can have almost nothing else in common in their charts.
