In astrological symbolism Aries is the spark at the start of the cycle: the urge to begin, try and act. It is linked with courage, directness and a competitive streak that often turns into strong self-motivation.

With Aries strong in a chart, clear goals and quick feedback usually beat long deliberation. Patience is the classic lesson here: turning a brilliant start into a finished story.

Aries as Sun, Moon and rising sign

Sun in Aries

An Aries Sun tends to meet life head-on. You may feel most like yourself when there is something to start, defend or figure out fast, and waiting around can feel almost physically uncomfortable. Your honesty is often refreshing; the growth edge is pausing long enough to bring others along.

Moon in Aries

With the Moon in Aries, feelings tend to arrive quickly and leave just as fast. You may process emotions by moving – a walk, a workout, a blunt conversation – rather than sitting with them. You often need room to act on your own terms to feel emotionally safe.

Aries rising

An Aries rising often comes across as energetic, frank and ready to go. People may notice your pace before anything else, and first impressions tend to be "this person gets things moving". You may approach new situations by jumping in and adjusting on the way.

Compatibility by element

As a fire sign, Aries tends to feel most at ease with other fire signs (Leo, Sagittarius) and to be energized by air signs (Gemini, Aquarius). Its opposite, Libra, often feels like a mirror: different, but complementary. Real compatibility depends on the whole chart, not on Sun signs alone.

The Aries constellation

The tropical sign Aries starts at the March equinox point (0°). Because of precession, the Sun is actually in front of the constellation Pisces at the March equinox today.

Questions

What are the Aries dates?

Aries runs from roughly March 21 to April 19. The exact day the Sun changes sign shifts by up to a day from year to year (and depends on your time zone), so if you were born on a boundary date, check your year with the zodiac sign calculator.

Is March 20 Aries or Pisces?

It depends on the year and time of birth. In many years the Sun enters Aries on March 20 (UTC), so a person born late on March 20 may be an Aries while someone born that morning is a Pisces. A calculator with your birth time settles it.

What planet rules Aries?

Mars is the traditional ruler of Aries. In the traditional scheme the Sun is also "exalted" in Aries.
