Born on October 31
Sun in Scorpio.
Your Sun sign
Anyone born on October 31 has the Sun in Scorpio. A Scorpio Sun is learning to go deep and survive its own transformations. The work of the sign is intensity with trust — depth that shares rather than only withstands.
The decan
October 31 falls in the first decan of Scorpio — roughly 0° to 10° of the sign. The first decan is the sign at its most undiluted. Everything the sign is known for shows up here with the least interference — for better and for worse, this is the purest expression of it. Here that sub-ruler is Scorpio itself, ruled by Pluto & Mars: a double dose rather than a blend.
The Egyptian decan
Long before the Greeks divided the sky into twelve, Egyptian astronomers cut the year into thirty-six decans of about ten days, each marked by the star that rose with the dawn. October 31 belongs to Sebi, decan 30 of thirty-six, whose rising star is Algol and whose traditional quality is transformation in darkness. This is a separate tradition from the western zodiac above, not a translation of it — the two were built from different sky-watching and they disagree in places.
The deity for this date
The Egyptian deity paired with this date is Sekhmet (Sekhmet) — Fire element, sacred animal the Lioness. Fierce and magnificent, Sekhmet souls burn with an inner fire that can heal or destroy. They are warriors and healers in equal measure, channeling immense power with precision. When they love, they love completely; when wronged, their wrath is legendary and absolute.
The day number
As a date, October 31 reduces to a 4 — structure, patience, and the instinct to build something that will still be standing later. This is the day number rather than your full Life Path, which needs the month and year as well — but it is the part of the calculation your birthday alone decides.
What a birth date cannot tell you
One thing worth being clear about: a birth date on its own fixes your Sun sign and very little else. Your Moon sign changes every two and a half days, and your Rising sign changes roughly every two hours and depends on where you were born. Two people who share October 31 can have almost nothing else in common chart-wise.
Two people share this birthday and almost nothing else
Your Moon sign needs a time, your Rising sign needs a time and a place. Six questions, no card.

What zodiac sign is October 31?
October 31 is Scorpio. The Sun is comfortably inside Scorpio on this date in every year, so unlike the eleven cusp dates there is no ambiguity here.
Which decan is October 31?
October 31 falls in the first decan of Scorpio, the 0–10° band, sub-ruled by Pluto & Mars. Decans divide each sign into three ten-degree sections, which is how two people of the same sign can read quite differently.
Does my birthday tell you my Moon sign?
No. The Moon crosses a sign every two and a half days, so a date alone cannot fix it — you need at least the year, and usually the time. Zodaiya's Moon sign calculator will tell you honestly when your date is not enough to settle it.
What is special about being born on October 31?
Astrologically: the Sun's position, the decan it falls in, and the Egyptian deity Sekhmet traditionally paired with this part of the year. What it does not fix is the rest of your chart, which is where most of the personal detail actually lives.
