An Aries Sun meets life head-on. You come alive when you can start something, take the first step or compete, and you tend to act before you overthink. The growth edge is patience: finishing what you begin.
These associations describe astrological tradition, rather than scientifically established personality traits. For the relationship angle, see Aries compatibility.
When does Aries season start and end?
Season year means the year the Sun enters Aries. Capricorn seasons end in January of the following year. The start is inclusive; the end belongs to the next sign.
Each tropical sign occupies 30° of ecliptic longitude, starting at the March equinox. We search the Sun’s apparent geocentric longitude with Astronomy Engine, using the same calculation as our Sun sign calculator. Times are rounded to the nearest minute; they are calculated estimates, not second-level guarantees. See our methodology and published JPL comparison.
All dates in these tables use UTC. A local birthday can fall on a different UTC date. For a personal answer near a boundary, enter your birth date, time and place in the calculator. At the transition the new sign begins; a person has one tropical Sun sign.
Tropical signs are equal sectors tied to the seasons, not the unequal astronomical constellations. Precession changes their alignment. These tables do not give IAU constellation crossing dates or sidereal signs.
