How to Identify Your Decan
This decan covers 0° up to but not including 10° of Aquarius.

This collection uses modern triplicity: sub-rulers follow the signs of the same element. Other systems, including Chaldean decans, assign different rulers. The descriptions below are interpretive traditions, not measured personality traits. Compare the decan methods at Astrodienst.
Pure Uranus Aquarius is the zodiac's true revolutionary. These individuals see the world not as it is but as it could be, and they feel a moral imperative to close that gap. Their minds operate on a frequency that most people cannot hear — inventive, iconoclastic, and genuinely indifferent to convention. They value ideas over emotions, progress over tradition, and humanity over individuals.
How This Decan Differs
First decan Aquarius is the most radically independent and intellectually unconventional of the three decans. Without Mercury's charm or Venus's warmth, they are pure Uranian revolution — brilliant, detached, and unapologetically different.
