Born on October 31
Your Sun is in Scorpio, about 8° in — the first decan, where Scorpio's core takes on a Mars flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Scorpio
The fixed water sign that goes to the depths and refuses to keep things shallow.
A Scorpio Sun is built around intensity and depth. You see through people — not always charitably, but accurately. The polite veneer most adults walk around in is transparent to you; you watch what people do, not what they say, and you remember. This makes you formidable in any field that rewards the willingness to look at uncomfortable things directly: therapy, investigation, surgery, research, art that doesn't flinch.

Your decan: the first decan of Scorpio
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 0–10 of Scorpio belong to Mars: your drive — how you take action, what makes you angry, and what you fight for. Read it as Scorpio with a Mars accent — the water core is unchanged, the emphasis moves.
Five of Cups
Loss · Regret · What remains. 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 Scorpios born on October 31 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
What zodiac sign is October 31?
October 31 is Scorpio, the fixed water sign ruled by Pluto. The Sun sits at roughly 8° Scorpio on this date, in the first decan.
What decan is October 31?
The first decan of Scorpio (0°–10°), 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 October 31?
In the Golden Dawn system each decan has a minor arcana card: for the first decan of Scorpio it is the Five of Cups (loss, regret, what remains). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on October 31 have the same chart?
No. They share the Sun in Scorpio, 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 October 31 in different years can have almost nothing else in common in their charts.
