Insights from an expert astrologer on the decans of Aries

Aries—dynamic, bold, and ambitious. Born between March 21st and April 19th, Aries is the first sign of the zodiac, ruled by Mars and represented by the ram. But does an Aries’ personality depend on which month or day they were born? You betcha, and we’re going to dive deep into the different variations of Aries with expert insight from Astrologer & Spiritual Teacher Kaitlyn Kaerhart. Read on for everything you need to know!

Section 1 of 7:

Why are March and April Aries different?

  1. The zodiac is divided into twelve equal sections, each of which represents one of the zodiac signs, and each section spans 30 degrees. Every section and sign is further divided into 3 “decans” of 10 degrees each, and corresponds to around 10 days.[1]
    • Each zodiac sign’s decans correspond to that sign’s triplicity, or element. Aries’ element is fire, and the other two fire signs are Leo and Sagittarius.
    • People born in the first 10 days of the sign are like a double dose of Aries, while those born in the second 10 days are influenced by Leo, and those born in the final 10 days are influenced by Sagittarius.[2]
