Aries dates and key facts
The conventional dates for Aries are March 21 – April 19. The exact start shifts a little from year to year: depending on the year, the Sun’s entry into Aries falls in the window March 20 – 21 (UTC), so if you were born on a boundary day, add your birth time and place in the calculator above. Aries is a fire sign of the cardinal modality, ruled by Mars; its symbol is the Ram. The opposite sign is Libra.
Aries personality
Aries opens the zodiac, and astrologers describe it as the sign of beginnings. As a cardinal fire sign ruled by Mars, it is traditionally linked with initiative, courage and a competitive streak. Aries types are said to think on their feet, prefer action to long discussion and enjoy a challenge for its own sake. The fire element is associated with enthusiasm and warmth, the cardinal modality with starting things, and Mars with drive and directness. The result, in the classic picture, is someone honest to the point of bluntness, quick to anger and just as quick to forgive.
Aries strengths and weaknesses
Strengths traditionally attributed to Aries: courageous, energetic, honest and decisive. Typical weaknesses: impatient, impulsive and quick-tempered. Traditionally, the lessons of Aries are patience and follow-through. Finishing what it started, listening before replying and counting to ten before reacting are classic pieces of advice for the sign. Aries is also said to grow by noticing that not every disagreement is a contest, and that asking for help can be its own kind of courage.
Aries in love
In love, Aries is traditionally described as a wholehearted pursuer: when it is interested, the other person usually knows it quickly. The early stage, with its excitement and chase, is said to suit Aries especially well, and the sign prefers honesty to hints or games. A partner with a mind of their own keeps Aries engaged, while too much routine or a sulky silence is said to cool things down. Aries is generous and protective once committed, but has to learn that a slower pace is not a lack of feeling. By the traditional rules used in our compatibility tool, the best matches for Aries are Leo, Sagittarius and Gemini.
Aries at work
At work, Aries is associated with starting projects, taking the lead and handling situations that need a fast decision. Astrologers often point the sign towards roles with variety, clear goals and some independence: running a business, sales, emergency services, sport, or any job where no two days are the same. Long approval chains and detailed maintenance work are said to test its patience. Aries tends to work best with a clear target and the freedom to choose the route, ideally next to colleagues who carry a project through after the first push.

How the calculator finds your sign
Your zodiac sign, also called your star sign or Sun sign, is the sign the Sun was in on the day you were born. With only a date, the calculator uses the conventional date ranges. The Sun does not change sign on the same day every year, though: depending on the year, the change can fall a day earlier or later. If you add your birth time and place, the tool computes the Sun’s exact ecliptic longitude and shows its degree, so a boundary (cusp) birthday is settled precisely. Daylight saving time is handled automatically, and the tool warns you when your date is a boundary day and no time has been entered.
Zodiac sign dates
The conventional dates are: Aries March 21 – April 19, Taurus April 20 – May 20, Gemini May 21 – June 20, Cancer June 21 – July 22, Leo July 23 – August 22, Virgo August 23 – September 22, Libra September 23 – October 22, Scorpio October 23 – November 21, Sagittarius November 22 – December 21, Capricorn December 22 – January 19, Aquarius January 20 – February 18 and Pisces February 19 – March 20. The calculator uses the tropical zodiac of Western astrology, which is tied to the seasons rather than to the constellations.
Elements, modalities and ruling planets
Each sign belongs to one of four elements (fire, earth, air, water) and one of three modalities (cardinal, fixed, mutable), and has a ruling planet; for Scorpio, Aquarius and Pisces both the modern and the traditional ruler are shown. Astrologers use these building blocks to describe a sign’s temperament: fire is associated with enthusiasm, earth with practicality, air with ideas and water with feelings. The result card also names your opposite sign and the three signs that score highest with yours in the compatibility tool.
Astrology is for entertainment
Astrology is a cultural tradition, not a science. There is no scientific evidence that the position of the Sun at birth shapes personality, relationships or the future. The descriptions on this page summarise what astrologers traditionally say about each sign. Enjoy them as a conversation starter, not as advice for real decisions.

Frequently asked questions
What is my zodiac sign?
It is the sign the Sun was in when you were born. Enter your date of birth above; for example, someone born on May 1 is a Taurus.
What if I was born on the cusp?
On boundary days the sign depends on the year and the exact time. Add your birth time and place and the calculator works out which side of the line the Sun was on.
Is a zodiac sign the same as a star sign or Sun sign?
Yes. All three terms mean the sign the Sun was in at your birth. Your Moon sign and rising sign are different and need a birth time.
Why do some websites give slightly different dates?
Because the Sun enters each sign on a slightly different day each year, sites round the boundaries differently. The calculator avoids this by computing the Sun’s actual position when you give a birth time.
Is this the tropical or the sidereal zodiac?
Tropical, as used in Western astrology. Vedic (sidereal) astrology usually places the Sun about one sign earlier.
