Aries
Mar 21 – Apr 19
About this sign
As the first sign of the zodiac, Aries bursts forward with the raw fire of Mars, its ruling planet. You are a natural pioneer who thrives on fresh starts, competition and the thrill of being first. Bold and direct, you say what you think and chase what you want without hesitation. Your enthusiasm is contagious, and few can match the sheer momentum you bring to any project once your heart is set on it.
Beneath the warrior spirit lives a surprisingly childlike honesty and warmth. You forgive quickly and rarely hold grudges, preferring action over brooding. Your challenge is patience: you may charge ahead before thinking things through, and routine can bore you. Learning to finish what you begin and to consider others' feelings turns your restless energy into genuine, lasting leadership that inspires everyone around you.

How Aries works
Fire is the element of impulse and self-expression. Fire signs act first and understand afterwards, which is a liability in a negotiation and an asset in a crisis — the hesitation other people feel simply is not there. Cardinal signs open each season, and they behave like it: they initiate. The recurring problem is not starting but finishing, since the interesting part was the beginning. Put those together and Aries is the cardinal face of fire — the specific combination only one sign in the zodiac has.
Aries is ruled by Mars, which is the body to watch if you want to know how an Aries is doing. When Mars is well placed, the sign's better qualities are easy to reach; when it is retrograde or under pressure, the same qualities turn brittle in a recognisable way.
Across the zodiac sits Libra, Aries's opposite sign. Opposites are not enemies in astrology — they are the missing half. Most of what Aries struggles to do naturally, Libra does without thinking, which is why the pairing is simultaneously the most difficult and the most instructive one on the wheel.
The three decans of Aries
Each sign covers thirty degrees, and the three ten-degree thirds — the decans — are traditionally governed by the rulers of the three signs sharing its element. Two people born three weeks apart are both Aries, but not quite the same Aries. Dates are approximate and shift by about a day between years.
- 1 March 21–30 · ♈ Aries decan, ruled by Mars
The first decan is the purest expression of Aries — Mars rules it twice over, so the sign's traits arrive undiluted.
- 2 March 31 – April 9 · ♌ Leo decan, ruled by Sun
The Sun adds a second flavour here: still Aries, but with a noticeable Leo accent to how it plays out.
- 3 April 10–19 · ♐ Sagittarius decan, ruled by Jupiter
Jupiter adds a second flavour here: still Aries, but with a noticeable Sagittarius accent to how it plays out.

Aries questions
What are the Aries dates?
Aries runs from March 21 to April 19. The exact boundary shifts by up to a day between years, because the Sun does not enter a sign at the same clock time every year — if you were born within a day of either end, a birth chart is the only way to be certain.
Who is Aries most compatible with?
On sun-sign scoring alone, Aquarius comes out highest, and the rest of the ranking is on this page. That said, a sun-sign score compares two twelfths of the population; it describes a tendency, not a verdict on a particular relationship.
Which sign is hardest for Aries?
Cancer scores lowest here, mostly because of the element mismatch and the angle between the two signs. Difficult pairings are not doomed ones — they simply need the differences named out loud rather than assumed away.
What planet rules Aries?
Mars. In practice that means its movements — the sign it is in, and whether it is retrograde — track the periods when an Aries feels most and least like themselves.
