♊Gemini
May 21 – June 20
Gemini dates are May 21 – June 20. If you were born in that window, the Sun was moving through Gemini — a mutable air sign ruled by Mercury.
Born a day or two either side? The boundary shifts slightly year to year. Just before May 21 belongs to Taurus; just after June 20 belongs to Cancer. Your birth time and city decide the edge cases.

Gemini is Mercury in air — thought as motion. Mutable and dual, Gemini holds contradictory positions comfortably and finds a single fixed identity slightly suffocating. Strong Gemini placements read quickly, talk to strangers easily, and metabolize information as a form of nourishment.
Strengths
- Fast, flexible intelligence
- Talks to anyone
- Sees the counterargument instantly
- Genuinely curious rather than performatively so
Challenges
- Scattered attention across too many threads
- Talking past the feeling
- Restlessness read as inconstancy
Gemini in love
Gemini falls for a mind first. Long silences read as distance; a partner who keeps talking keeps Gemini present.
Gemini at work
Gemini excels where variety is the job — writing, sales, teaching, anything requiring rapid translation between audiences.
Who Gemini tends to get along with
By element, Gemini shares an easy language with the other air signs and with air and fire signs generally. It's a starting point, not a verdict — two whole charts decide the rest.

Gemini questions, answered
- What are the Gemini dates?
- Gemini dates are May 21 to June 20. If you were born on or before May 20 you are Taurus; if you were born after June 20 you are Cancer.
- Is Gemini a air sign?
- Yes. Gemini is a mutable air sign ruled by Mercury.
- What signs are most compatible with Gemini?
- Traditionally Gemini pairs easily with the other air signs and with air and fire signs generally — Aries, Leo, Libra, Sagittarius, Aquarius. Real compatibility depends on the whole chart, not the Sun sign alone.
- Do the Gemini dates shift from year to year?
- Slightly. The Sun enters Gemini around May 21 each year, but the exact moment moves by up to a day depending on the year and your time zone. If your birthday falls on the boundary, your birth time and city settle it.
How Aether reads Gemini
A Sun in Gemini is one voice in a much larger chart. Aether computes your Moon, rising sign, and the rest of your placements from your birth date, time, and city, then writes each day's resonance from those placements against the current transits — and from the moods and events you log in your chronicle. Where a generic Gemini horoscope generalizes across a twelfth of the world, your reading is drawn from your chart alone.
