Gemini

Gemini is the third sign of the zodiac, known for its curiosity, adaptability, and dual nature.

Gemini is the third sign of the zodiac, covering birthdays from approximately May 21 to June 20. Represented by the Twins (Castor and Pollux), Gemini is an air sign ruled by Mercury. People with strong Gemini placements are often curious, communicative, and quick-witted. The sign's dual nature reflects a love for variety and a tendency to see both sides of any issue.

How it works

In a natal chart, Gemini rules the third house of communication, siblings, short trips, and early education. If your Sun, Moon, or rising sign is in Gemini, you likely have a restless mind that craves new information. Gemini is a mutable sign, meaning it adapts easily to change. Mercury as its ruler gives a sharp intellect and a talent for words. In a chart, Gemini placements often show up as a fast speaking style, a love for writing or teaching, and a need for mental stimulation.

In practice

When interpreting Gemini in a reading, notice how the person processes information. They may juggle multiple interests or change opinions often. Gemini energy is playful and social, but can scatter if not grounded. A well-aspected Gemini is a natural networker; a stressed one might struggle with consistency. Look at the house Gemini occupies to see where this curiosity plays out — in friendships, work, or learning.
