Dates and the edge days

Aquarius dates are January 20 to February 18. January 20 and February 18 are the edge days: the year and the birth time can put the Sun on either side of the change. The calculator checks that moment instead of trusting the printed range.

Element, mode, and ruler

Aquarius is an air sign, and it is fixed. Aquarius is fixed air, the middle of northern winter. Fixed signs are described as holding a pattern. In Aquarius the pattern the books talk about is an idea shared with a group. Independent, idea-led, a little apart from the crowd.

Older texts give Aquarius to Saturn. Many current books name Uranus. This site lists Uranus, and the Saturn note is the older assignment, not an extra result from the calculator. Aquarius is the water bearer, an air sign despite the water in the picture. The inherited description is independence, an interest in the group rather than the private pair, and a willingness to stand slightly apart. Air signs are the thinking group. The jug of water is a star picture, not a claim about emotion.

Moon in Aquarius

An Aquarius Moon is described as feelings that cool off when they can be thought about, and that dislike emotional pressure. Comfort, in this tradition, is a friend who does not crowd. The Moon's sign is still a timed astronomical place.

Aquarius rising

Aquarius rising is the textbook first impression of someone a little detached and easy to spot as their own person. It changes with the hour. Use the rising calculator rather than the Sun-sign dates.

Sign and constellation

The constellation Aquarius is the water bearer, a wide and mostly faint pattern. The sign is the air sign that follows Capricorn.

Calculators

For the Sun sign, use the zodiac calculator. The Moon, Rising, Mercury, Venus, and Mars calculators answer a different question, and the Aquarius horoscope is a separate daily note on the same sign.

Questions

What are Aquarius dates?

Aquarius dates are January 20 to February 18 in the usual tropical calendar. Those two edges are changeover days: the year and the birth time can put the Sun in Aquarius or in the neighboring sign. Each date page below uses noon UTC, the same engine as the zodiac calculator, so you can see whether that birthday stays in Aquarius.

What month is Aquarius?

Aquarius season sits in January and February. It does not fill either month on its own. January 20 is the usual start, and February 18 is the usual last day, with a clock time that shifts a little each year. Use the date list on this page, or the January and February birthday hubs.

When does Aquarius season start?

Aquarius season usually starts on January 20. That is the calendar day when the Sun is treated as entering Aquarius, but the exact minute depends on the year. The zodiac calculator uses the same tropical longitude as these pages. If the birthday is January 20 or February 18, check the year rather than the printed range.
