Aquarius at a Glance

When Does Aquarius Start and End?

Aquarius season begins on January 20 and ends on February 18. You may see these dates listed a day earlier or later on other sites — that’s not an error. The Sun doesn’t change signs at the same clock time every year, so the exact start and end can shift by about a day depending on the year and your time zone. For almost everyone, January 20–February 18 is exactly right. Born right on the edge? See the cusp section below.

Were You Born on the Aquarius Cusp?

Born right at the edge of Aquarius? You were born on a cusp — the changeover point between two signs. January 20 sits on the Capricorn–Aquarius cusp; February 18 sits on the Aquarius–Pisces cusp. Astrologically, there’s no such thing as being “half and half” — you’re fully one sign or the other. The only way to know for certain is to check the exact moment the Sun changed signs in your birth year, since a boundary birthday can fall under either sign depending on the year and hour you were born.

The Three Decans of Aquarius

Every sign divides into three decans of roughly ten days, each with a sub-ruler that shades the core personality:

• First decan (January 20–29): ruled twice over by Uranus and Saturn — the purest, most classic Aquarius expression.
• Second decan (January 30–February 8): shaded by Mercury (Gemini), adding wit and a stronger, more sociable curiosity.
• Third decan (February 9–18): shaded by Venus (Libra), adding charm and a stronger pull toward partnership.

Aquarius Personality in Brief

As an air, fixed sign ruled by Uranus (and Saturn), Aquarius is independent, original, and humanitarian — the zodiac’s visionary and free thinker.

• Strengths: innovative, independent, humanitarian, intellectual, deeply loyal to causes and friends
• Weaknesses: detached, unpredictable, stubborn, can struggle with emotional vulnerability

Aquarius Compatibility Snapshot

Aquarius pairs most naturally with fellow air signs Gemini and Libra — shared love of ideas, independence, and social connection — plus fire signs Aries and Sagittarius, who match Aquarius’s energy and appetite for new experiences. Aquarius and Leo, sitting opposite each other on the wheel, often create a magnetic push-pull precisely because they’re so different — Leo brings warmth, Aquarius brings detachment. Aquarius and Gemini build one of the zodiac’s most stimulating, idea-driven partnerships. Taurus and Scorpio tend to need the most patience as matches, since their more possessive, emotionally intense style can clash with Aquarius’s need for independence.
