The Protector

Cancer zodiac sign

21 June to 22 July

Element WaterQuality CardinalRuler Moon

Cancer feels deeply and protects what is close to its heart. This sign carries an invitation to trust your own instincts and to offer, as well as to receive, a sense of warmth and belonging.

What are the dates of the Cancer zodiac sign?

The Cancer zodiac sign runs from 21 June to 22 July. During this period, the Sun, as seen from Earth, moves through the section of the zodiac assigned to Cancer. The sign before it is Gemini, and the sign that follows is Leo.

Born on a cusp day? The Sun's exact entry into a new sign shifts by a few hours from year to year. Anyone born on 20 June/21 June or on 22 July/23 July, on what is known as the “cusp”, may actually fall into the neighboring sign, depending on their birth year and time. The only way to be certain is an exact calculation using your date, time, and place of birth, for example in a personal Birth Chart Book.

What are the three decans of Cancer?

The three decans of Cancer divide the sign into three equal sections of 10° each. Traditional astrology assigns a sub-ruler from the same element to each decan, giving its core quality a slightly different shade:

DecanDegreesPeriodSub-ruler
1st Decan0°–10°approx. 21 June to 30 JuneMoon (pure Cancer quality)
2nd Decan10°–20°approx. 1 July to 10 JulyPluto (Scorpio note)
3rd Decan20°–30°approx. 11 July to 22 JulyNeptune (Pisces note)

These periods are approximate calendar dates. What matters is the exact degree of the Sun, which a calculated birth chart shows precisely.

What does the Cancer zodiac sign mean?

As a water sign, Cancer is associated in astrology with feeling, intuition, and inner depth. As a cardinal sign, it opens a season and is considered initiative-taking: it sets things in motion. Cancer is traditionally ruled by the Moon, the planet of emotion and the need for security. This makes Cancer one of the receptive signs: inward-looking and absorbing.

Important: these are traditional associations, not a fixed judgment about any person. They describe a tendency that can unfold, offered as an invitation to self-reflection, not as a prediction.

Is your sun sign the whole story?

No. Your star sign only tells you where the Sun was at the moment you were born, and that is something you share with one twelfth of the world's population. Where your Moon falls, which Ascendant was rising, and how the planets relate to one another, that is what makes you truly unique. A personal Birth Chart Book shows you exactly this complete picture: Sun, Moon, Ascendant, all the planets in their houses and the aspects between them, all in a book written solely about you.

Anyone who wants to explore the three most important placements first will find them in the Astro Bite Your Big Three.
