The four zodiac elements

Born on a sign boundary?

These are the UTC dates on which the Sun changes signs in at least one year from 1950–2050. Check the year table for the date, then convert your local birth time to UTC.

How these dates are calculated

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.

Astrology is a symbolic and cultural tradition. The planetary positions on this site are calculated with astronomical accuracy; the interpretations describe what astrologers associate with them and are not scientifically validated predictions about personality, relationships or the future.
