What it means
Aquarius is an air sign and a fixed sign, a mix that makes it open to new ideas but firm once it holds a view. Its symbol is the water bearer, pouring out water for everyone, often read as sharing knowledge with the community. Modern astrology gives Aquarius to Uranus, the planet of sudden change and invention, while traditional astrology gives it to Saturn, which adds structure and seriousness. The Codex calls the Aquarius Sun the visionary, whose purpose is to disrupt the status quo and aid the collective. It tends to shine when it is authentic and forward-thinking.
Strengths
Originality, fairness, loyalty to friends, clear thinking, and comfort with being different.
Challenges
Emotional distance, fixed opinions, rebelling for its own sake, and caring about humanity more easily than about one person.
Dates
The Sun moves through Aquarius from about January 20 to February 18. The exact dates shift by a day or so from year to year, so if you were born near either edge, your birth time and place decide which sign your Sun is in. A free blueprint calculates it exactly.
How Cosmic Array reads it
Your Sun is one part of the chart, not the whole of it. The Moon and Rising sign change the picture: an Aquarius Sun with a Cancer Moon may argue for big social causes in public and still want a close, cozy circle at home. Cosmic Array also reads your Sun against your numerology and Human Design, and where they pull in different directions, the blueprint names that tension instead of picking one side.
