Astrology Signs and Their Dates at a Glance
The primary date ranges below reflect tropical zodiac signs most commonly used in Western astrology. Note that exact dates can shift by a day in some year-to-year astrological calculations due to calendar adjustments; when the Sun changes signs near a date boundary, verify the year-specific chart if you were born on that edge.

| Aries | March 21–April 19 | Early spring | Fire | Cardinal |
| Taurus | April 20–May 20 | Late spring | Earth | Fixed |

Why Tropical Zodiac Dates Are Standard in This Reference
This profile uses the tropical zodiac, which fixes Aries at 0° declination of longitude and aligns signs with season-based divisions. It is the default framework in Western astrology and horoscopic traditions used in most English-language contexts. While some traditions use sidereal zodiacs that track actual stellar constellations, tropical dates remain the predominant reference for astrology signs and their dates in daily practice, compatibility, and horoscopic work.
Understanding Sign Boundaries and Cusp Clarifications
Being born within a date range does not automatically mean the Sun was in that sign at your birth; precise placement depends on time and location. On dates near a sign transition, a natal chart calculation is necessary to confirm the Sun’s position. If you were born on a cusp date, you may hear terms like “cusp” or “in between,” but astrologically the Sun is either wholly within one sign or another; mixed influences arise from planetary placements, not the Sun being on a boundary.
Practical Guidance When Dates Are Near a Boundary
- If your birth date falls within two days of a sign change, check a trusted ephemeris or natal chart generator using your exact time and location.
- Use an astrology chart calculator to confirm house and sign positions rather than relying on generalized cusp descriptions.
- When in doubt, treat the Sun sign as the sign the Sun occupied at the moment of your birth according to chart data, not solely on a generic date list.
Astrology Signs vs. Constellations: A Key Distinction
Western astrology signs are tropical markers tied to seasonal patterns rather than current constellation shapes or sizes. The dates listed correspond to the tropical framework, not the variable astronomical boundaries of constellations. If you encounter astronomy-based claims about “new signs” or “Ophiuchus,” these do not replace the standard tropical sign system used for astrology signs and their dates in mainstream practice.
