The 3 Types of Gemini

Not every Gemini is the same. Your decan — set by your exact birth date — reveals which of the three faces of Gemini is truly yours.

Astrologers split each sign's 30 degrees into three decans of 10 degrees, each coloured by a different sub-ruling planet. It's why a Gemini born at the start of the season can feel noticeably different from one born at the end. Here are the three Gemini decans — their personalities, strengths, growth edges and love styles. Find yours by your birthday.

First Decan May 21 – 31

The Communicator · ruled by Mercury

Double Mercury gives this Gemini the quickest wit of the zodiac — endlessly curious, talkative, playful and mentally restless. They collect ideas and people like treasures and can talk their way into (and out of) anything.

Their mind moves at the speed of light and their mouth tries to keep up. Endlessly curious, they gather facts, stories and friends, and can find common ground with almost anyone. Boredom is their greatest enemy, so they’re forever seeking the next conversation, idea or plot twist.

Strengths

  • Wit
  • Adaptability
  • Social ease

Growth edges

  • Restlessness
  • Scattered focus

In love: They need constant mental spark and a partner who keeps the conversation alive.

Second Decan June 1 – 10

The Charmer · ruled by Venus

Venus softens Gemini into a social, flirtatious diplomat who loves art, beauty and connection. Warm and magnetic, this decan charms every room and turns conversation into an art form.

Softer and more romantic than the typical Gemini, this decan turns charm into an art form. They love beauty, harmony and a little flirtation, and glide through social situations with ease. Light, frequent, delightful connection is what they live for — they make everyone feel interesting.

Strengths

  • Charm
  • Diplomacy
  • Creativity

Growth edges

  • Indecision
  • People-pleasing

In love: Playful and affectionate, they fall for wit, beauty and easy chemistry.

Third Decan June 11 – 20

The Visionary · ruled by Saturn / Uranus

The Aquarian sub-ruler gives this Gemini surprising depth and originality — an inventive, humanitarian thinker drawn to big ideas and the unconventional. They are the most independent and future-facing of the three.

The most original and independent Gemini, this decan thinks in possibilities others haven’t imagined yet. Humanitarian, inventive and a little detached, they’re drawn to big ideas, technology and progress, and they guard their freedom of thought fiercely. They’d rather be authentic than agreeable.

Strengths

  • Originality
  • Vision
  • Open-mindedness

Growth edges

  • Detachment
  • Aloofness

In love: They need a partner who is also a best friend and respects their independence.

Gemini decans — FAQ

What is a decan in astrology?

Each zodiac sign spans 30 degrees, which astrologers divide into three 10-degree "decans." Every decan has its own sub-ruling planet that colours the sign, which is why two Gemini born weeks apart can feel quite different.

How do I know which Gemini decan I am?

Simply check your birth date. The first decan of Gemini runs May 21 – 31, the second June 1 – 10, and the third June 11 – 20. Your birthday tells you which of the three "types" of Gemini you are.

Which Gemini decan is the most "Gemini"?

The first decan (May 21 – 31) is considered the purest expression of Gemini, because it is ruled twice over by the sign's own planet — making these traits the strongest and most classic.

Do decans really affect personality?

Decans are a traditional astrological tool for adding nuance, not a scientific fact. They're a fun, insightful way to understand the subtle differences between people of the same sign.
