Aquarius zodiac dates: boundaries, decans and meaning

Aquarius dates are conventionally listed as January 20–February 18 in Western tropical astrology. If you were born close to either boundary, check the Sun’s position for your birth year and time instead of relying on a date range alone.

The associations in a horoscope are symbolic interpretations. The date lookup and the interpretation are two different parts of the reading.

January and February Aquarius birthdays

Aquarius spans the end of January and much of February in conventional tropical date tables. Both parts belong to the same sign. A person born near the January boundary may need to check Capricorn; near the February boundary, Pisces.

What changes between Aquarius decans?

Decans divide the thirty-degree sign into three equal sections. Their date labels are approximate, and the planetary associations depend on the tradition used. A table that calls the middle decan “the smartest” is making a claim about people, not explaining that division.

Autonomy, friendship, ideas and collective projects are themes found in symbolic Aquarius readings. They can be explored through a concrete question, such as how much space you want within a shared project. Birth date alone does not tell you whether a partner will be distant, how intelligent you are or which job you should choose.

How to check a birthday near the boundary

Use your birth date, year, local time and birthplace to check the Sun’s tropical longitude. Aquarius follows Capricorn and precedes Pisces. At a specific birth instant, the Sun has one longitude; being close to the boundary does not assign two Sun signs.

Astroideal’s birth-chart calculator, in Spanish can show the Sun’s position. Choose the unknown-time option if you do not know the hour and read any range or uncertainty shown. The ascendant calculator, also in Spanish adds the rising sign when the necessary birth information is available.

Does this date range tell me who I am compatible with?

It identifies the conventional Sun sign. A broader astrological comparison may also examine Moon, Venus, Mars, ascendant and the angles between positions. People’s preferences, conversations and choices still matter more than trying to make a relationship fit a label.

For a simple symbolic exercise, the compatibility calculator in Spanish compares the elements of two conventional Sun signs. Its result is a conversation prompt, not a percentage of relationship success.
