Aquarius — the sign of independence and common cause

The eleventh sign of the zodiac, air and fixed. It has two rulers — Uranus and, classically, Saturn — and the sign describes the manner of holding to your idea and your company, even against general opinion.

What Aquarius colors in a chart

A sign describes the manner of whatever stands in it, so “Aquarius” in a chart means different things — depending on what has fallen into the sign.

Sun in Aquarius

Tradition links the Sun in Aquarius with independence of mind: a person arrives at their views with their own head and holds to them stubbornly — the sign is fixed. Things are done through people and ideas, best of all in a team of like-minded people where no one is the boss. Pressure and rules for the sake of rules provoke protest. This isn't about you if it's more comfortable for you to do as is customary and you don't want to argue with general opinion.

Moon in Aquarius

The Moon in Aquarius calms down at a distance: stepping back, looking from the side, discussing with friends rather than with the closest. Emotional pressure and a demand to share feelings at once make it want to leave. It needs freedom even inside close relationships. This isn't about you if in a hard moment you need only closeness and no distance.

Ascendant in Aquarius

With Aquarius rising, a person is read as different: a manner of their own, unexpected turns in conversation, friendliness to everyone with distance from each. It is hard to guess what they'll say next. In Moscow Aquarius rises for less than an hour a day, so exact birth minutes matter here. This isn't about you if new acquaintances consider you predictable and easily guess what you'll say.

Aquarius at the start of a house

Aquarius at the start of a house makes the sphere unusual and collective: it has its own rules, friends and unexpected turns. At the start of the 10th house — work in a team, with technology or new ideas; at the start of the 4th — a home arranged not like everyone's, where friends are welcome. The flip side is a chill where warmth is expected. This isn't about you if in the sphere of this house everything is like everyone else's and by common rules.

The other planets in Aquarius are read the same way: the planet’s role plus the sign’s manner. What each one means — Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

Where traditions differ

Here the traditions diverge. Before Uranus was discovered in 1781, Aquarius was ruled by Saturn, and classical astrology still holds this; modern astrology gave the sign to Uranus. The two rulers argue less than it seems: Saturn is loyalty to your principle, Uranus a break with the familiar. The Sun here is, classically, in detriment. In the calculation the site names both rulers.

Jyotish counts the signs from the stars: by our calculation with the Lahiri ayanamsa the Sun enters Kumbha (Aquarius) only on February 12–13, and most of those who are Aquarius by horoscope have the Sun there in the previous sign — Makara (Capricorn).

How to check it on yourself

Each statement below may turn out to be false about you — that’s how it’s written. Check it against your past, and write your answer down before you compare it with the chart. The first item checks the calculation itself, the rest — the interpretation.

  1. If your birthday is between January 19–21 and February 18–19

    What should match. From January 22 to February 17 the Sun is in Aquarius in any year from 1950 to 2030 — that’s what our calculation for Moscow time shows. January 19–21 and February 18–19 are border days: the Sun changes sign within the day, and the answer depends on the year, hour and time zone of birth.

    When it’s not about you. The day is a border day, and the sign was taken from a horoscope table rather than calculated for the year and hour — then “Aquarius” may turn out to be Capricorn or Pisces. This checks the calculation, not the interpretation.

  2. If your Moon is in Aquarius

    What should match. Recall your last three emotionally hard conversations with loved ones. After at least two you needed to be apart for a while before returning to the topic.

    When it’s not about you. In two cases out of three you, on the contrary, wanted not to let the other person go and to finish talking at once — this isn't about you.

  3. If your Sun is in Aquarius

    What should match. Recall three cases when your opinion differed from the majority's — in the family, at work, in a group. In at least two you stay with yours and say so out loud.

    When it’s not about you. You usually agree with the majority or stay silent — this isn't about you.

Frequently asked questions

What are the dates of Aquarius?

By our calculation for 1950–2030, the Sun enters Aquarius on January 19, 20 or 21 and leaves it on February 18 or 19 (Moscow time; farther east the boundary can fall a day later). From January 22 to February 17 it’s Aquarius in any year; on the border days the sign depends on the year and hour of birth.

Who rules Aquarius — Saturn or Uranus?

Classical astrology names Saturn, modern — Uranus, discovered in 1781. The site shows both and advises looking at both positions: wherever these planets stand in your chart, that's where tradition looks for the affairs of Aquarius.

Which signs is Aquarius compatible with?

Tradition sees the signs of the same element — Gemini and Libra — and the signs two steps away — Aries and Sagittarius — as easy for Aquarius; Taurus and Scorpio as tense; and the opposite sign, Leo, as attractive and difficult at once. This compares Suns only: for a couple, astrologers look at both full charts, and there is no data that signs predict how lasting a couple will be.
