Cancer dates
June 21 – July 22Cancer season runs roughly June 21 – July 22, but the boundaries are not fixed to the calendar: the Sun crosses into Cancer at a specific minute that shifts each year. Across 1980–2030 the entry falls on June 20 or 21 and the exit into Leo on July 22 or 23. In 2026 the Sun enters Cancer on June 21 at 08:25 UTC.
Born on a boundary day? Your sign depends on the hour — compute your chart and it's settled in a minute, or look up your birthday for the crossing time in your birth year.
About Cancer
01 · The shape of the signCancer is the part of the chart that holds people. Ruled by the Moon and made of water, Cancer is built around emotional memory and care. The crab symbol is well-chosen: the soft inside, the hard shell, the way it walks sideways when it doesn't trust where it's going. Where Cancer lives in your chart is where you build a home, protect what's vulnerable, and remember every detail of who hurt you and who didn't.
A Cancer Sun is built around emotional intelligence. You feel the room before anyone has spoken; you know who's about to cry, who's lying, and who's having a bad week. This is a real gift. It's also exhausting. The world doesn't have an off switch for empathy, and you absorb things you didn't sign up to absorb.
Home matters to you in a way that's deeper than aesthetics — not "home as in décor" but "home as in nervous-system safety." The right house, the right people in it, the right rituals — these are not nice-to-haves for you. They're the foundation that makes the rest of your life possible. When your home life is wrong, everything is wrong; when it's right, you can do almost anything.
Your loyalty runs hard. Once someone is in your circle, you'd burn things down for them — and you remember exactly who showed up when you needed them and who didn't. The shadow of this is grudge-holding: the crab's shell is hard, and it doesn't reopen easily. Forgiving without forgetting is a Cancer skill that has to be learned consciously. Your growth edge is keeping the depth without letting the depth become a moat.
Cancer Moon
02 · Inner emotional lifeA Cancer Moon is the Moon in its home sign — your emotional life is amplified. You feel everything, and everything sticks. You self-soothe through home, family (chosen or biological), food, and ritual. You're the friend who shows up with soup. The flip side is that you can't always tell where your feelings end and someone else's begin; protecting your own emotional space matters more for you than for most.
Cancer Rising
03 · How you arriveA Cancer Rising comes across as gentle and slightly guarded. People sense softness in you — they want to confide, to lean on you — but they also sense you're not opening the inner ring quickly. First impressions are warmth wrapped around watchfulness. Your face changes more than most people's; people read your moods before you announce them. You take a while to fully trust new environments, and that's healthy.

05 · Strongest matchesThe signs Cancer typically clicks with — usually those sharing element + polarity, or sitting across the chart in a complementary opposition. Compatibility is more about chart-to-chart aspects than sun signs alone, but these are good starting points.
