Gemini dates and key facts
The conventional dates for Gemini are May 21 – June 20. The exact start shifts a little from year to year: depending on the year, the Sun’s entry into Gemini falls in the window May 20 – 22 (UTC), so if you were born on a boundary day, add your birth time and place in the calculator above. Gemini is an air sign of the mutable modality, ruled by Mercury; its symbol is the Twins. The opposite sign is Sagittarius.
Gemini personality
Gemini is the mutable air sign ruled by Mercury, the planet astrologers connect with thinking, language and exchange. Its symbol, the Twins, is often read as a sign of two sides: Gemini is said to see several angles at once and to change its mind when new information arrives. The air element is linked with ideas and social contact, the mutable modality with flexibility, and Mercury with speed and curiosity. In the traditional picture, Gemini loves conversation, news, books and short trips, learns quickly and keeps many interests going at once, sometimes more than it can finish.
Gemini strengths and weaknesses
Strengths traditionally attributed to Gemini: curious, adaptable, witty and communicative. Typical weaknesses: restless, inconsistent and easily distracted. The traditional lessons of Gemini are focus and depth. Choosing a few interests to explore properly, finishing one project before starting the next and listening as much as talking are classic pieces of advice for the sign. Gemini is also said to grow by showing its feelings directly instead of explaining them away with a joke.
Gemini in love
In love, Gemini is traditionally described as needing a meeting of minds first. Long talks, shared jokes and a partner who brings new ideas are said to matter more to the sign than grand romantic gestures. Gemini can be playful and flirtatious, and it is thought to dislike feeling pinned down too early. Once engaged, it is an entertaining companion who keeps the relationship lively. The classic challenge is depth: Gemini is said to grow in love when it lets conversations turn to feelings, not only to facts and plans. By the traditional rules used in our compatibility tool, the best matches for Gemini are Libra, Aquarius and Aries.
Gemini at work
At work, Gemini is associated with communication, quick learning and juggling several tasks. Astrologers often connect the sign with writing, journalism, teaching, sales, marketing, translation, IT support or any role with variety and plenty of contact with people. Gemini is said to thrive where information moves fast and to lose interest in repetitive tasks without a visible purpose. It works well in teams that value ideas and talk things through. Some structure, such as lists, deadlines and a colleague who enjoys detail, helps Gemini turn its many ideas into finished work.

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.
