Cancer Zodiac Sign: Dates, Traits and Personality

The Cancer zodiac sign takes in birthdays from June 21 to July 22, give or take a few hours at each edge depending on the year. It is the fourth sign, a cardinal water sign ruled by the Moon, and its season begins at the June solstice, the start of summer in the Northern Hemisphere. You can see how Cancer fits among all twelve signs in the zodiac guide; what follows is the crab in detail.

Cancer dates and the solstice moment in 2026

Cancer is one of the four signs that begin exactly at a solstice or an equinox, so its start is easy to pin down. In 2026 the June solstice, and with it the Sun's ingress into Cancer, came at 4:24 a.m. EDT on June 21 (08:24 UTC). A birth on June 21 before 4:24 a.m. Eastern is Gemini; from 4:24 a.m. on, the sign is Cancer.

The other edge came earlier than the table. The Sun left Cancer for Leo on July 22 at 3:13 p.m. EDT, so a birth on July 22, 2026, from 3:13 p.m. on is a Leo, even though most lists still show Cancer for the whole day. The site's own astronomy engine supplies these instants, shown here in Eastern time. For any other year, or a birth in another time zone, the zodiac sign dates tool checks the Sun's position for your date.

Water, cardinal, ruled by the Moon

Cancer is the first water sign of the zodiac, with Scorpio and Pisces completing the group. Water is the element of feeling and attachment in astrological tradition. Cancer's modality is cardinal, the same starting quality that Aries, Libra and Capricorn share, which gives this gentle-seeming sign a surprising amount of initiative once someone it loves needs protecting.

The Moon rules Cancer, and it is the only sign the Moon rules. The Moon moves through the whole zodiac in about four weeks and changes sign every two to three days, and tradition reads that quick rhythm into Cancer's changing moods. Across the circle sits Capricorn: Cancer tends the home and the private world, Capricorn the public world and its structures. The crab is the symbol, a creature with a hard shell over a soft body, and the glyph ♋ is often read as two claws or two curled shapes side by side.

Cancer traits: care and its shadow

The heart of Cancer, in the tradition, is care. The crab looks after people, remembers birthdays and old stories, and builds a sense of home wherever it goes. Loyalty runs deep, and so does intuition about what others are feeling. A Cancer often notices first when someone in the room is having a hard day.

The shell has a purpose, and it also has a cost. When Cancer feels hurt, tradition says it retreats sideways, the way a crab walks, instead of saying so directly. Moods can shift quickly, old wounds can be held for a long time, and the wish to protect can slide into holding on too tight. Keep what you recognize and set the rest aside. The sign itself depends on where the Sun stood when you were born.

Cancer in love and compatibility

Tradition sees Cancer as a devoted partner who wants a real home with someone. Trust comes slowly, and once it is there, the crab gives a great deal: attention, comfort, a place to land. What Cancer needs back is reassurance and a partner who does not treat feelings as a nuisance.

Tradition finds the warmest matches among the other water signs. Cancer and Scorpio share emotional depth and a need for loyalty, and Cancer and Pisces share gentleness and imagination. Cancer and Capricorn, the opposite-sign pairing, joins home and ambition. For a fuller answer about two specific people, the compatibility calculator reads both charts.

Cancer at work

Cancer brings its caring instinct to work. Tradition connects the sign with teaching young children, nursing, hospitality, food, history and real estate, fields that deal in comfort, memory or shelter. Within any team, a Cancer is often the one who holds the group together and remembers what each person needs. A cold or hostile workplace wears the crab down faster than hard work does.

Beyond the Sun in Cancer

Your Sun sign is the familiar part. Your Moon sign, which for a Cancer carries extra weight because the Moon is the sign's ruler, shows the emotional core, and your rising sign shows the face you turn to the world. A Cancer with an Aries rising may look bold and fast even when the inner life is tender.

Cancer comes after Gemini and before Leo in the zodiac.
