Someone who is born on Halloween falls under which astrological sign of the zodiac?

Scorpio is the eighth astrological sign in the Zodiac, originating from the constellation of Scorpius. It spans 210°–240° ecliptic longitude. Under the tropical zodiac (most commonly used in Western astrology), the Sun transits this area on average from October 23 to November 22.

Scorpio is one of the three water signs, the others being Cancer and Pisces. It is a fixed, negative sign. In ancient times, Scorpio was associated with the planet Mars. After Pluto was discovered in 1930, it became associated with Scorpio instead.

Scorpio is associated with three different animals: the scorpion, the snake, and the eagle (or phoenix). The snake and eagle are related to the nearby constellations of Ophiuchus and Aquila. Scorpio is also associated with the Greek deity Artemis, who is said to have created the constellation Scorpius. Scorpio's colours are deep red, maroon, brown, and black.

Halloween or Hallowe'en is a celebration observed in several countries on 31 October, the eve of the Western Christian feast of All Hallows' Day.
