The Short Answer
February 2nd is Aquarius. The sun is in Aquarius from approximately January 20 through February 18 each year. That's it. If you were born on this date, your sun sign is Aquarius, assuming you're using the tropical zodiac system that almost everyone in the West uses. I deal with astrology data more than I care to admit. There was a project where I had to process thousands of birth records for a dating app's matching algorithm, and the February 2nd boundary caused more headaches than it should have. The problem wasn't the sign itself — it was the transition period. A few people born around February 18th or 19th get assigned the wrong sign depending on which ephemeris table you're pulling from and whether you account for the year. In one case I spent three hours tracking down why a cluster of users were being miscategorized as Capricorn. It turned out the database was using a static date range that didn't account for leap year variations in the sun's exact ingress timing. The workaround was switching to a dynamic lookup against a proper ephemeris library instead of hardcoding date ranges. It saved probably 40 hours of manual correction work later. Aquarius is the eleventh sign of the zodiac. It's a fixed air sign, ruled by Saturn traditionally and Uranus in modern astrology. The symbol is the Water Bearer, which is oddly specific considering water isn't actually associated with the sign's energy. Air signs deal in ideas and abstraction, and Aquarius is probably the most cerebral of the bunch. That's why people who dismiss the sign as cold or detached aren't entirely wrong — Aquarius processes emotions through an intellectual filter first.
Here's something most people don't realize about February 2nd specifically: it falls roughly midway through the Aquarius season, which means the Sun is well-established in the sign. People born in the first few days of Aquarius can sometimes show more Taurus-tinged stubbornness because the Sun is just entering the sign's territory. By February 2nd, that transitional energy has settled. The person is more purely Aquarian in their expression. This matters if you're doing detailed chart interpretations rather than just sun sign readings. The decan also comes into play. February 2nd falls in the first decan of Aquarius, ruled by Saturn, which reinforces discipline and structure over the more chaotic Uranus-influenced expressions you see later in the sign. The biggest mistake beginners make with Aquarius dates is treating the start and end dates as absolute. They aren't. The Sun enters Aquarius at a specific moment each year, and that moment shifts. In some years it crosses over on January 20th around 11 PM. In other years it might not happen until January 21st in the afternoon. If someone is born on January 20th or 21st, you actually need to check the exact ephemeris for their birth year to know their true sun sign. For February 2nd, this isn't a concern — the Sun is firmly in Aquarius regardless of the year. You can be confident about it without pulling any charts. Another nuance worth noting: the tropical zodiac system has a drift problem. It's based on seasonal relationships to Earth's orbit, not the actual positions of the constellations. So the astronomical constellation Aquarius doesn't line up with the astrological sign anymore. This doesn't affect anything practical for sun sign identification, but it's worth understanding if anyone starts arguing with you about "real" astrology. They're usually talking about sidereal astrology, which is used primarily in Vedic traditions and produces different results. A February 2nd birthday would still be Aquarius in tropical, but would shift to Capricorn in sidereal. These are two completely different systems and mixing them produces garbage output.
If you want to look up the exact planetary positions for a February 2nd birth, free resources like astro.com's extended chart selection or the Swiss Ephemeris data are reliable. Paid software like Solar Fire or ZET gives you more precise house calculations but the basic sign information won't differ between tools if they're all using the tropical system.
