♈Aries
March 21 – April 19
Aries dates are March 21 – April 19. If you were born in that window, the Sun was moving through Aries — a cardinal fire sign ruled by Mars.
Born a day or two either side? The boundary shifts slightly year to year. Just before March 21 belongs to Pisces; just after April 19 belongs to Taurus. Your birth time and city decide the edge cases.
- Element
- Fire
- Modality
- Cardinal
- Ruler
- Mars
Aries is the opening degree of the zodiac — the impulse before the plan. Ruled by Mars and cardinal by modality, Aries energy initiates: it starts the conversation, takes the first step, says the thing everyone else is circling. People with strong Aries placements tend to think by moving, and to trust the version of an idea that arrives fastest.
Strengths
- Decisive under pressure
- Physically courageous
- Direct, unlayered honesty
- Starts things others only discuss
Challenges
- Impatience with slow processes
- Heat that arrives before context
- Losing interest after the beginning
Aries in love
Aries pursues plainly and dislikes strategy in romance. The relationships that last are the ones where directness is met with directness rather than managed.
Aries at work
Aries does its best work at the front of a project — launches, pitches, crises. Long maintenance phases drain it; pairing with a fixed sign usually solves that.
Who Aries tends to get along with
By element, Aries shares an easy language with the other fire signs and with air and fire signs generally. It's a starting point, not a verdict — two whole charts decide the rest.
Not sure it's your sign?
Enter the day you were born and we'll name the Sun sign that holds it.
Aries questions, answered
- What are the Aries dates?
- Aries dates are March 21 to April 19. If you were born on or before March 20 you are Pisces; if you were born after April 19 you are Taurus.
- Is Aries a fire sign?
- Yes. Aries is a cardinal fire sign ruled by Mars.
- What signs are most compatible with Aries?
- Traditionally Aries pairs easily with the other fire signs and with air and fire signs generally — Gemini, Leo, Libra, Sagittarius, Aquarius. Real compatibility depends on the whole chart, not the Sun sign alone.
- Do the Aries dates shift from year to year?
- Slightly. The Sun enters Aries around March 21 each year, but the exact moment moves by up to a day depending on the year and your time zone. If your birthday falls on the boundary, your birth time and city settle it.
How Aether reads Aries
A Sun in Aries is one voice in a much larger chart. Aether computes your Moon, rising sign, and the rest of your placements from your birth date, time, and city, then writes each day's resonance from those placements against the current transits — and from the moods and events you log in your chronicle. Where a generic Aries horoscope generalizes across a twelfth of the world, your reading is drawn from your chart alone.
