Aquarius Zodiac Sign: Dates, Traits and Personality

The Aquarius zodiac sign runs from January 20 to February 18 by the usual table, with each edge able to move by some hours from year to year. Aquarius is the eleventh sign, a fixed air sign with two rulers, Saturn in the classical scheme and Uranus in modern astrology. Its season is the heart of winter. The name often misleads people: despite the water bearer, Aquarius belongs to air. All twelve signs appear together in the zodiac guide; this page stays with Aquarius.

Aquarius dates and the 2026 changeover

The start of Aquarius in 2026 is a clear case of the time zone deciding the date. The Sun crossed from Capricorn into Aquarius at 01:45 UTC on January 20. On the East Coast that was 8:45 p.m. EST on January 19. A New York birth on January 19 after 8:45 p.m. is therefore Aquarius, while a London birth at the same instant carries the date January 20. Most tables would call January 19 Capricorn.

The season ended on February 18 at 10:52 a.m. EST, when the Sun moved into Pisces. The usual table counts all of February 18 as Aquarius; in 2026 only the morning before 10:52 a.m., Eastern time, was. The Sun positions behind these times are computed by the NovaOracles astronomy engine. In other years both edges shift, and the zodiac sign dates tool checks the Sun's position for any single birthday.

Air, fixed, with two rulers

Gemini and Libra are the other two air signs, and Aquarius comes last of the three. Air stands for thought and connection, and in Aquarius it reaches beyond a pair of people toward groups, networks and society as a whole. The fixed quality makes Aquarius steady in its convictions, which can surprise anyone expecting the flighty side of air.

Saturn ruled Aquarius in classical astrology, and that link explains the sign's seriousness about principles and systems. When Uranus was discovered in 1781, the first planet found with a telescope, modern astrologers gave it to Aquarius and tied the sign to sudden change, invention and rebellion. Most modern charts list both. The opposition is Leo. Leo puts the individual heart in the center; Aquarius puts the group there. The symbol is a figure pouring water from a jar, and the glyph ♒ shows two wavy lines, read as water or as currents of air and energy.

Aquarius traits and personality

Tradition describes Aquarius as independent and original. The water bearer thinks for itself, questions the usual way of doing things and often cares about causes larger than its own life. Aquarius is said to be friendly with almost everyone, loyal to friends and open to people others overlook. The sign often keeps one eye on the future and on how people might live together better.

The shadow grows from the same independence. Detachment is the classic Aquarius difficulty: a habit of stepping back into the head when feelings get close. Being fixed, Aquarius can also be stubborn about its opinions, and a love of being different can turn into contrarian habit. They may or may not match you; the sign itself is decided by where the Sun stood when you were born.

Aquarius in love and compatibility

In love, Aquarius is said to need friendship first. The water bearer wants a partner who respects its space and its causes, and who enjoys a good conversation about the future. Possessiveness and heavy emotional demands early on tend to send it the other way.

The air signs are read as the smoothest match. Gemini and Aquarius share curiosity and a quick mind, and Libra and Aquarius share ideals and a sense of fairness. Across the wheel, Leo and Aquarius is the opposite-sign pairing, with the individual and the group learning from each other. The compatibility calculator looks at two full charts for a real answer.

Aquarius at work

At work, tradition links Aquarius with technology, science, engineering, social causes and anything that builds the future. The water bearer often has ideas nobody else thought of, works well in a team of equals and dislikes rigid hierarchy. Being told to do things a certain way just because they have always been done that way is what frustrates Aquarius most.

More than an Aquarius Sun

An Aquarius Sun describes one strand of a birth chart. The Moon sign shows what you need emotionally, and the rising sign, which depends on your exact birth time and place, shows how you come across. An Aquarius with a Cancer Moon, for example, may be far warmer and more home-loving than the textbook picture. The big three tool combines the three, and the rising sign calculator gives you the ascendant.

Aquarius comes after Capricorn and before Pisces.
