All Capricorn season times, 1950–2050
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.
