Gemini — The Twins
A quick, Mercury-ruled air sign, Gemini carries the communicative energy of early summer. As a mutable sign it is traditionally seen as flexible and curious, happy to gather ideas and move lightly between them. In astrology it is associated with conversation, wit, versatility, and a lively, sociable mind. Tradition casts it as the zodiac's talker and connector, curious about a little of everything.
What tradition gives Gemini

The myth underneath
Named for the twins Castor and Pollux of Greek and Roman myth.
Tradition pairs Gemini most easily with Libra, Aquarius, Aries — a folk pattern about temperaments, not a rule about people.

The edges, honestly
Sign boundaries are not fixed calendar dates — the Sun's ingress moves by a day or so from year to year. Computed across 1930–2030, these dates near Gemini's edges belong to different signs in different years:
| Date | Usually | Sometimes |
|---|---|---|
| May 21 | Gemini in 72% of years | Taurus otherwise |
| June 21 | Gemini in 61% of years | Cancer otherwise |
