Exact Aries Dates and Calendar Period
Aries spans from March 21 to April 19 in the tropical zodiac, marking the first sign of the zodiac calendar. The Sun enters Aries at the vernal equinox, when the Sun crosses the celestial equator moving northward. This period aligns with the start of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. The Aries constellation is located in the Northern celestial hemisphere and is visible during winter and spring evenings.
The Aries date range remains fixed each year, though the exact Sun-entry time shifts slightly due to leap years and time zones. In 2024, the Sun entered Aries on March 20 at 03:06 UTC. The next Sun entry into Aries occurs around March 19 or 20 annually. The tropical zodiac used by Western astrology defines Aries as the first 30 degrees of ecliptic longitude. Astronomically, the Sun is in the Aries constellation from late April through mid-May, which differs from the astrological dates.
Aries Element, Ruling Planet, and Key Traits
Aries belongs to the fire element alongside Leo and Sagittarius, representing energy, action, and initiative. Mars rules Aries as both the traditional and modern planetary ruler, influencing drive, assertiveness, and physical vitality. Aries is classified as a cardinal sign, which means it initiates action and leads seasonal transitions. Cardinal fire signs are associated with leadership, pioneering spirit, and directness.
Common Aries traits include high energy, competitiveness, courage, and a preference for immediate action. The Aries birthstone is the diamond, and the Aries birth flowers are the honeysuckle and thistle. The Aries tarot card association is The Emperor, symbolizing authority and structure. Aries is considered a masculine, positive sign in astrological gender classification, and its quality is active rather than receptive.
Aries Compatibility and Notable Aries Figures
Aries is most compatible with Leo and Sagittarius in romantic and friendship pairings due to shared fire-element energy. Aries also shares strong compatibility with Gemini and Aquarius through dynamic, stimulating connections. The most challenging pairings for Aries are typically Cancer and Capricorn due to elemental and modality clashes. Aries rising and Aries Moon placements influence emotional expression and first impressions differently than the Sun sign alone.
Notable Aries figures include actors, athletes, and entrepreneurs born between March 21 and April 19. The Aries period is associated with the start of new projects, athletic events, and leadership ventures.
