  question: What is Gemini in astrology?
  answer: >-
    Gemini is the third sign of the zodiac May 21 – June 20 , a mutable air sign
    ruled by Mercury. Gemini energy is curious, adaptable, communicative, and
    multi-faceted — the cosmic conversationalist who gathers information from
    everywhere and connects ideas others never see as related.

    - 'Symbol: The Twins'
faq:
  - question: Why is Gemini called the twins?
    answer: >-
      The Twins symbol represents Gemini's duality — the ability to see multiple
      perspectives, hold contradictory views simultaneously, and adapt to any
      social context. It's about multiplicity, not deception.
  - question: What is Gemini most compatible with?
    answer: >-
      Gemini is most compatible with Libra and Aquarius (air signs) and Aries
      and Leo (fire signs that energize Gemini's mind). Sagittarius, the
      opposite sign, creates a philosophical polarity.
  - question: Are Geminis two-faced?
    answer: >-
      The 'two-faced' stereotype oversimplifies Gemini's genuine
      multidimensionality. Geminis have the gift of adaptability — they adjust
      their communication style to context. This can look inconsistent to those
      who prefer a single fixed persona.
  - question: What does Gemini rule in astrology?
    answer: >-
      Gemini rules the 3rd house (communication, siblings, local travel), the
      lungs and hands, and all forms of information exchange.

# Gemini Zodiac Sign

Gemini is the third sign of the zodiac (May 21 – June 20), a mutable air sign ruled by Mercury. Gemini energy is curious, adaptable, communicative, and multi-faceted — the cosmic conversationalist who gathers information from everywhere and connects ideas others never see as related.

**Gemini** is the zodiac's most restlessly curious mind — eternally seeking new information, new perspectives, and new conversations. The Twins represent not deception but multiplicity: Gemini contains multitudes.

## Core Traits

Quick-witted, adaptable, talkative, and endlessly curious, Gemini moves through life collecting knowledge and connections. The challenge is depth — Gemini's breadth is impressive, but sustained focus on one thing can feel like a cage.

## Gemini and Communication

Mercury-ruled Gemini excels in writing, teaching, journalism, podcasting, social media, and any field requiring agile communication. They are natural networkers who know everyone.

## Gemini in Love

Gemini needs mental stimulation in relationships. A partner who can surprise them intellectually holds their attention far longer than one who is merely attractive. Boredom is Gemini's greatest relationship risk.

## Gemini Season (May 21 – June 20)

Gemini season brings social energy, new conversations, short trips, and an appetite for variety. A good time to learn, connect, and share ideas.

## Gemini in Daily Life

Gemini energy is curious, adaptable, and communicative. In a birth chart, this sign colors whatever house cusp or planet it touches. A Sun in Gemini expresses identity through these qualities; a Moon in Gemini processes emotion through them; an Ascendant in Gemini presents them as a first impression.

The highest expression of Gemini uses its gifts without becoming trapped in the shadow. The work is to keep the strength flexible and the weakness conscious. Every sign has both — the chart simply shows where you are invited to practice.
