Aquarius Zodiac Sign
Aquarius Zodiac Sign: fixed-air meaning, Water Bearer symbol, approximate dates, Saturn and Uranus traditions, chart method, and limits.
Overview
Aquarius Zodiac Sign: Aquarius is the eleventh tropical zodiac sign, spanning 300° to 330° of ecliptic longitude. Its glyph is ♒, the Water Bearer, but its element is fixed air rather than water. It is active or yang, traditionally ruled by Saturn, associated with Uranus in modern astrology, and opposite Leo. Approximate Sun-sign dates are January 20 to February 18, but exact boundaries vary by year and time zone. Astrology uses Aquarius to ask how systems, principled dissent, networks, and durable reforms operate. It does not prove genius, rebellion, coldness, politics, technology, friendship, compatibility, or a fixed personality.

Definition and scope
Aquarius has the air element, fixed modality, and active/yang polarity. Its traditional ruler is Saturn. Some modern schools also associate it with Uranus; this is a later overlay. Seasonal and mythic context comes from midwinter and the water-bearer, while the opposite sign Leo supplies the balancing axis.
Balanced Aquarius expression develops systems, peers, dissent, abstraction, collective rules, and future models with responsiveness; imbalanced expression overuses the same pattern or collapses into its stereotype. The Sun shows identity and purpose here, the Moon regulation and need, Rising first approach and body rhythm, Mercury thinking, Venus relating and value, and Mars action. Relationship, career, and growth readings must keep those placements distinct.
Evidence and method
OpenFate's reproducible calculation layer returns the chart fields listed above. Reading tools may build traditional narratives from them, but personality, compatibility, and outcomes are not objective measurements or guarantees.
Confirm the body’s exact longitude and declared zodiac before assigning Aquarius. For a Sun-sign question, check the Sun’s degree rather than an approximate date alone. Keep the Water Bearer symbol separate from the air element, use Saturn as traditional ruler, and label Uranus as a modern association. Then read planet as what, Aquarius as how, house as where, and aspects as modifiers. Keep Aquarius Sun, Moon, Ascendant, eleventh house, politics, and technology as separate questions.
Example and near-miss
Illustrative case, not proof: A public library required a fixed address for every membership card, excluding people in temporary housing. A staff member gathered anonymized rejection counts, compared policies in three cities, and piloted identity verification through partner shelters. The team reviewed fraud and access after ninety days, then changed the rule with a published appeal process. Aquarius symbolism appeared in system redesign shared by a network, not in contrarian style or technology for its own sake. The replacement also remained open to correction.
Variants and context
Modifiers and context: Fixed air may maintain an equitable principle or become attached to an abstract future that ignores present users. Compare participation before and after the redesign; do not assume an Aquarius Uranus.
Near-miss and alternative: An employee refusing a new procedure because of a personal dispute may look rebellious. A private conflict is not collective reform unless the objection identifies a shared barrier and tests an alternative.
Limits and verification
Stop rule: Aquarius does not prove genius, political belief, friendship, social popularity, detachment, or future technology. Evaluate institutions through outcomes, rights, accessibility, and accountable governance.
Aquarius uses OpenFate editorial synthesis for traditional symbolism; it is not scientific evidence or a causal claim.
