Aquarius: Dates, Personality, Love Style and Compatibility

Aquarius dates and how to check a cusp birthday

Aquarius covers 300° to 330° of celestial longitude. In the East Asian solar calendar it runs from Daehan (대한, Major Cold) to just before Usu (우수, Rain Water), the stretch when Korean winter is at its coldest and then begins, very slowly, to soften. Standard dates are January 20 to February 18, and calculated for 1930 to 2050 in Korea time, Aquarius has started on January 20 or 21.

In 2026 Aquarius began at 10:45 am Korea time on January 20 (1:45 am UTC), and the Sun moved into Pisces at 12:52 am Korea time on February 19, which was 3:52 pm UTC on February 18. In other words, someone born in London on the evening of February 18, 2026 is a Pisces, while a Seoul baby born that evening is still an Aquarius.

The Pisces start date moves between February 18 and 20, so birthdays from February 18 to 20 need checking, as do January 19 to 21 at the Capricorn end. Compare your birth time with the exact ingress times for your year and time zone using an ephemeris or a cusp calculator.

Aquarius season also contains a boundary that Korean readers care about: Ipchun (입춘), the 'Start of Spring' solar term, which usually falls between February 3 and 5. In saju, the Korean Four Pillars of Destiny, your tti (띠), the zodiac animal, changes at Ipchun rather than on January 1 or at Lunar New Year. So an Aquarius born in late January belongs to the previous year's animal, while one born after Ipchun belongs to the new one. In 2027, for example, Ipchun falls at about 10:46 am Korea time on February 4: an Aquarius born before that is a Horse, after it a Goat. If you have an early-February birthday, check both your sign and your animal.

Symbol and myth: Ganymede, who fills the cup of the gods

Aquarius, the Water Bearer, is usually identified with Ganymede, a beautiful Trojan youth in Greek myth. Zeus, in the form of an eagle, carried him up to Mount Olympus to become cupbearer to the gods, pouring nectar and ambrosia at their feasts. To console Ganymede's father, Zeus gave him fine horses, and he later set Ganymede in the stars, along with the eagle, the constellation Aquila.

Long before the Greeks, the Babylonians saw a figure pouring water in these stars and associated them with the rainy season and with Ea, god of waters. The name Aquarius means 'water carrier', yet it is an Air sign: the water it pours is often read as knowledge, ideas and inspiration shared with all of humanity.

That is why Aquarius is associated with progress, community and the future. Traditionally ruled by Saturn, it was given the modern ruler Uranus after that planet's discovery in 1781, a fitting match for a sign of invention, revolution and surprise. The glyph ♒ shows two wavy lines, flowing water or waves of energy.

Aquarius personality: strengths and blind spots

Aquarius combines the Air element, the realm of thought and connection, with the fixed modality that sustains each season. With Saturn and Uranus as rulers, traditional astrology describes a sign that is both principled and unconventional. The Moon and rising sign can greatly change how these themes show up in a real chart.

• Originality: Aquarius thinks differently and is not afraid to be the odd one out. New ideas and unusual solutions come naturally.
• Humanitarian spirit: this sign cares about fairness, community and the bigger picture, and often supports causes and movements.
• Friendliness: Aquarius gets along with all kinds of people and values friendship highly, often keeping a very diverse circle.
• Independence: the Water Bearer needs freedom to think and live its own way.
• Blind spot, emotional distance: Aquarius may analyse feelings rather than feel them, which can look cool or aloof.
• Blind spot, stubbornness: as a fixed sign, it can hold on to its views firmly, even while championing open-mindedness.

Aquarius love style

For Aquarius, love often grows out of friendship. Traditional readings describe a partner who wants a relationship of equals, built on shared ideas, mutual respect and plenty of personal space. Aquarius is drawn to people who are interesting, independent and a little unusual, and it may surprise partners with unconventional ways of showing affection.

The challenge is emotional intimacy. Aquarius can seem detached, especially when emotions run high, and may need time alone to process feelings. Partners who do not cling, who enjoy their own interests and who can talk about big ideas bring out the Water Bearer's loyalty, which runs deeper than its cool exterior suggests. In return, an Aquarius who learns to say how it feels, not only what it thinks, becomes a steadfast and refreshingly honest companion.

Aquarius compatibility

Traditional sun-sign compatibility reads the angles between signs: 120° for the same element, 60° for complementary elements, 180° for the opposite sign and 90° for the square. Treat these patterns as something to explore for fun and self-reflection, not as fixed rules.

Aquarius at work and with money

Traditional astrology sees Aquarius thriving in innovative, future-oriented and people-centred work. Science and technology, software and engineering, research, social enterprise and non-profits, activism, urban planning, aviation and space, and the creative arts are all classic Aquarius fields. The sign does best where it can experiment, collaborate with like-minded people and work toward a cause.

The traditional caution is resisting authority or routine, and losing interest in the practical details of a vision. With money, Aquarius can be unconventional: unbothered by status spending but drawn to new technologies, causes and experimental ideas. A simple system that runs automatically suits a sign that would rather think about the future than track receipts. This is a description of traditional temperament, not financial advice.

The real constellation Aquarius

The real Aquarius is large but faint, so it can be hard to find. Its brightest star is Beta Aquarii, Sadalsuud, at about magnitude 2.9, very slightly brighter than Alpha, Sadalmelik. The water jar appears as a small Y-shaped group of stars, and the stream of water flows down toward Fomalhaut, the bright star of Piscis Austrinus, the Southern Fish. From Korea and similar latitudes, Aquarius is best seen in the southern sky on evenings from September to November, especially in October.

Because of precession, during astrological Aquarius (January 20 – February 18) the Sun is mostly in front of the real Capricornus. Someone born on February 3, 2000, for instance, is an Aquarius in astrology, but the Sun was actually among Capricornus' stars that day. By the International Astronomical Union (IAU) boundaries, the Sun passes through the real Aquarius from about February 17 to about March 12.

The equinox point keeps moving westward and will eventually enter Aquarius, which is where the phrase 'the Age of Aquarius' comes from. When that happens depends on how the constellation boundaries are drawn, so estimates vary widely.

Lucky correspondences are tradition

The colours, gems and days linked with Aquarius reflect Air and Uranus. They are traditional correspondences to enjoy as a theme, not rules. The body-part association comes from medieval astrology and is not a basis for any health judgement.
