Cancer: Western zodiac dates and meaning
Cancer illustration
Cancer arrives with early summer and Water-element symbolism. Home, tides, and mood weather show up a lot in the cultural stories.
Date range on this site
For calculator results we treat Cancer as June 21 to July 22. Ranges are inclusive and use local calendar dates. If you were born on a cusp day, another chart might tip you into Leo; we stick to one consistent map so results do not flip between page loads.
Element
Cancer is grouped as a Water sign. Water signs in this system are Cancer, Scorpio, and Pisces. Element language is folklore structure, not chemistry.
Tropical zodiac vs the night sky
The Western system used here is tropical: twelve equal slices tied to seasons around the year. That is different from pointing a telescope at the constellation once named Cancer. NASA and astronomy educators regularly explain that astrology did not get a surprise new calendar from a lab press release; the mismatch between signs and modern constellation dates is old celestial geometry, not a personality update.
Birth month gems are separate
A birthday can have both a Western sign and a month birthstone. Those charts answer different questions. If you want the jewelry-month story, browse birthstones.

Common questions
When is Cancer?
On this site, Cancer covers June 21 to July 22 in the tropical (season-based) Western zodiac. Some charts shift cusps by a day.
Is Cancer a science fact?
No. Zodiac signs are cultural astrology labels. Astronomy describes stars and seasons; it does not assign personality by birth date.
Why might my constellation not match my sign?
Tropical signs follow seasons, not today's constellation boundaries. Earth's axis has also drifted since ancient charts were drawn, so star backgrounds and sign names no longer line up the way many people assume.
