Gemini at a Glance

When Does Gemini Start and End?

Gemini season begins on May 21 and ends on June 20. You may see these dates listed a day earlier or later on other sites — that’s not an error. The Sun doesn’t change signs at the same clock time every year, so the exact start and end can shift by about a day depending on the year and your time zone. For almost everyone, May 21–June 20 is exactly right. Born right on the edge? See the cusp section below.

Were You Born on the Gemini Cusp?

Born right at the edge of Gemini? You were born on a cusp — the changeover point between two signs. May 21 sits on the Taurus–Gemini cusp; June 20 sits on the Gemini–Cancer cusp. Astrologically, there’s no such thing as being “half and half” — you’re fully one sign or the other. The only way to know for certain is to check the exact moment the Sun changed signs in your birth year, since a boundary birthday can fall under either sign depending on the year and hour you were born.

The Three Decans of Gemini

Every sign divides into three decans of roughly ten days, each with a sub-ruler that shades the core personality:

• First decan (May 21–31): ruled twice over by Mercury — the purest, most classic Gemini expression.
• Second decan (June 1–10): shaded by Venus (Libra), adding charm and a stronger pull toward harmony and partnership.
• Third decan (June 11–20): shaded by Uranus and Saturn (Aquarius), adding originality and a more independent streak.

Gemini Personality in Brief

As an air, mutable sign ruled by Mercury, Gemini is curious, quick-witted, and communicative — endlessly adaptable and social.

• Strengths: witty, expressive, adaptable, curious, a natural connector of people and ideas
• Weaknesses: inconsistent, easily bored, prone to overthinking, can come across as indecisive

Gemini Compatibility Snapshot

Gemini pairs most naturally with fellow air sign Libra and Aquarius — shared love of ideas, conversation, and social connection — plus fire signs Aries and Leo, who match Gemini’s energy and spontaneity. Gemini and Sagittarius, sitting opposite each other on the wheel, often spark a lively, adventurous connection precisely because they’re both restless, freedom-loving signs. Gemini and Virgo share ruling planet Mercury, giving them an easy verbal shorthand, though Virgo’s need for order can clash with Gemini’s spontaneity. Pisces tends to need the most patience as a match, since its emotional depth can feel harder for Gemini to read. For a full compatibility reading, try the Love Compatibility Calculator.
