Cancer decans — three divisions within one sign
A sign spans thirty degrees, so the Sun sits nearly twenty degrees apart at the start and the end of the same sign. Classical astrology split that span into three ten-degree decans and assigned each one a different ruler drawn from the same element.
Decan 1
0°~10°
6.21~7.1
Sub-ruler: Moon
The Moon doubled gives the widest emotional range. The ability to read a room is exceptional here — things are noticed before they are said. Other people's feelings come in as though they were one's own, which makes deliberate boundary-setting a genuine skill to practise.
Decan 2
10°~20°
7.2~7.12
Sub-ruler: Pluto
Pluto deepens and prolongs the feeling. Loyalty to whatever has been taken to heart runs remarkably deep, and so does the mark left by injury. Bringing things out and working through them recovers faster than burying them, however unnatural that feels.
Decan 3
20°~30°
7.13~7.22
Sub-ruler: Neptune
Neptune lets imagination and empathy spread without edges. Talent often surfaces in art or in caring work. The grip on practical reality can loosen, so external anchors — numbers, calendars, deadlines — do real work here.
Cancer compatibility — the other eleven signs
The elements (fire, earth, air, water) set the baseline, but even within one element the cardinal, fixed and mutable qualities change the texture. Each pairing below is read on its own terms.

Contrasting match
Aries and Cancer run on different currents. Accept that you show feeling differently and keep a distance that neither of you has to strain to hold.
Cancer × Aries in detail →Gemini
Contrasting match
Gemini and Cancer: the head and the heart move differently. Listen to what Cancer feels and the distance closes quickly.
Cancer × Gemini in detail →Leo
Contrasting match
Cancer and Leo: feeling against pride. Say the words that acknowledge each other often and the knots come loose.
Cancer × Leo in detail →Libra
Contrasting match
Cancer and Libra: emotion against equilibrium. What Cancer wants is usually not a solution but recognition, so hold the verdict a moment.
Cancer × Libra in detail →Sagittarius
Contrasting match
Cancer and Sagittarius: security against freedom. Sagittarius promising a time to return and Cancer seeing them off restores the balance.
Cancer × Sagittarius in detail →Aquarius
Contrasting match

The following draws on mythology and observational astronomy, separate from the personality reading above.
Myth and origin
While Heracles fought the Hydra, Hera sent a crab to hinder him. It pinched his foot and was crushed almost at once. The part is a small one against such a hero, and the tradition holds that Hera placed the crab among the stars to honour that loyalty. It is the most sacrificial role in the zodiac, and the devotion associated with Cancer traces back to it.
Finding it in the night sky
This is the faintest constellation in the zodiac and is all but invisible from a city. What redeems it sits at the centre: the Beehive Cluster, which the unaided eye catches from a dark site as a soft smudge of light. When Galileo first turned a telescope on that smudge it resolved into more than forty stars. Spring is the season to look.
A common misconception
Cancer is described as a summer sign yet cannot be seen in summer. Its season means the Sun lies in that direction, sharing the daytime sky with it. Every sign is hidden during its own weeks; Cancer, having no bright stars to spare, shows the effect most starkly.

Exactly when Cancer begins and ends
Cancer period (KST)
| Year | Begins | Ends |
|---|---|---|
| 2025 | Jun 21, 11:42 | Jul 22, 22:29 |
| 2026 | Jun 21, 17:25 | Jul 23, 04:13 |
| 2027 | Jun 21, 23:11 | Jul 23, 10:05 |
Ingress times are computed with the Swiss Ephemeris. Cancer begins the instant the Sun reaches 90° of ecliptic longitude.
Born on the cusp?
In 2026, Cancer runs from Jun 21, 17:25 to Jul 23, 04:13. Anyone born before that opening moment belongs to the previous sign, Gemini; anyone born after it is Cancer. If your birthday falls on a boundary date, you need your time of birth to settle it.
Cancer begins at the same moment as Summer Solstice in the 24 solar terms, and ends at Greater Heat.
