Star sign dates - What are the 12 zodiac signs? - Cosmopolitan
Including the typical character traits of each star sign, too
www.cosmopolitan.comHere’s the latest overview on astrological sign dates and recent chatter around them.
-
The core Sun-sign dates are traditionally fixed in Western astrology, with commonly cited ranges like Aries (Mar 21–Apr 19) and Pisces (Feb 19–Mar 20). Recent online discussions have circulated claims of updated ranges that shift boundaries, but major outlets and astrology sites remain divided on whether a formal, universally accepted revision has occurred. The most reliable references still present the classic ranges, while fringe sources propose small adjustments based on solar positions.[3][4]

In 2021–2025, a number of articles and posts claimed new dates aligning signs with current stellar positions, particularly around Aquarius and Pisces, but major traditional sources (Britannica, established astrology sites) have not adopted a single, authoritative new set. If you’re curious about potential changes, it’s helpful to compare multiple sources per sign to see where they agree or differ.[4][5][3]

Public interest on this topic often spikes when headlines claim “updated zodiac signs,” but many scientists and educators emphasize that astrology and celestial coordinates use different systems (tropical zodiac vs. sidereal positions). The tropical (season-based) system used in most Western astrology hasn’t officially adopted a global redefinition of sign dates, despite occasional media chatter.[8][4]
Illustration: If you want a quick reference, you can compare a traditional set (Aries Mar 21–Apr 19; Taurus Apr 20–May 20; etc.) against a proposed revised set (e.g., shifting boundaries by a day or two). The practical effect is small for most people unless you were born near a sign cusp. Example: someone born on Feb 19 or Mar 20 might be aligned with Aquarius or Pisces depending on the source, but many horoscopes still label them as Aquarius or Pisces by the conventional ranges.[5][3]
Would you like me to pull and compare the latest sign-date definitions from a few reputable sources side-by-side for your birth date, or focus on how to interpret cusp dates if you were born near the boundary?[3][4]
