♋Cancer
June 21 – July 22
Cancer dates are June 21 – July 22. If you were born in that window, the Sun was moving through Cancer — a cardinal water sign ruled by The Moon.
Born a day or two either side? The boundary shifts slightly year to year. Just before June 21 belongs to Gemini; just after July 22 belongs to Leo. Your birth time and city decide the edge cases.
- Element
- Water
- Modality
- Cardinal
- Ruler
- The Moon
Cancer is the Moon's own sign: tidal, protective, and long-memoried. Cardinal water initiates through care — Cancer is the one who notices what's missing in a room and quietly supplies it. Strong Cancer placements feel weather changes in a relationship days before anyone names them.
Strengths
- Emotional accuracy
- Fierce protection of chosen people
- Builds homes anywhere
- Remembers what mattered
Challenges
- Withdrawing instead of stating a need
- Holding an old injury past its usefulness
- Caretaking as a way of avoiding being cared for
Cancer in love
Cancer commits early and privately. It needs to be chosen out loud; assumed security is not the same as expressed security.
Cancer at work
Cancer builds team cohesion others don't notice until it's gone. It struggles most in environments that treat feeling as noise.
Who Cancer tends to get along with
By element, Cancer shares an easy language with the other water signs and with earth and water signs generally. It's a starting point, not a verdict — two whole charts decide the rest.

Cancer questions, answered
- What are the Cancer dates?

- Yes. Cancer is a cardinal water sign ruled by The Moon.
- What signs are most compatible with Cancer?
- Traditionally Cancer pairs easily with the other water signs and with earth and water signs generally — Taurus, Virgo, Scorpio, Capricorn, Pisces. Real compatibility depends on the whole chart, not the Sun sign alone.

- Slightly. The Sun enters Cancer around June 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 Cancer
A Sun in Cancer 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 Cancer horoscope generalizes across a twelfth of the world, your reading is drawn from your chart alone.
