Birth chart for Cancer
Your Sun in Cancer is one placement out of ten. It's the part every Cancer shares; the other nine are what make your chart yours. Here's what is fixed, what can vary, and how your birth time decides the rest.

What every Cancer chart has in common
The Sun in Cancer: a cardinal water sign ruled by Moon. In 2026 the Sun enters Cancer on June 21 at 08:25 UTC and moves into Leo on July 22; across recent decades the season starts on June 20 or 21 and ends on July 22 or 23, so the boundary days depend on the year and hour.
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.
Mercury and Venus: the placements that can't wander far
Two planets are tied to the Sun by geometry. Mercury never sits more than about 28° from it, so a Cancer Sun always has Mercury in Gemini, Cancer, Leo. Venus stays within about 47°, so it lands in Taurus, Gemini, Cancer, Leo, Virgo — most often the middle three. That's why Cancers think and love in a recognisable handful of styles rather than twelve.
Your Moon: twelve possibilities
The Moon changes sign every two to three days, so it can be anywhere. It is the biggest single reason two Cancers feel different from each other. Pick yours:
- Cancer Sun, Aries Moonpioneering · direct · brave

Birth time: your rising sign and where the Sun sits
At sunrise the Sun is on the horizon, so a Cancer born at dawn has Cancer rising and the Sun in the 1st house. Every two hours or so the horizon moves one sign along and the Sun climbs one house. This table is a rough guide — the ascendant's speed changes with latitude and season — but it shows why the time matters.
| Born | Rising sign (approx.) | Sun's house |
|---|---|---|
| Around sunrise | Cancer rising | 1st house |
| ~2 h after sunrise | Leo rising | 12th house |
| Late morning | Virgo rising | 11th house |
| Around midday | Libra rising | 10th house |
| Early afternoon | Scorpio rising | 9th house |
| Late afternoon | Sagittarius rising | 8th house |
| Around sunset | Capricorn rising | 7th house |
| Early evening | Aquarius rising | 6th house |
| Late evening | Pisces rising | 5th house |
| Around midnight | Aries rising | 4th house |
| The small hours | Taurus rising | 3rd house |
| Before dawn | Gemini rising | 2nd house |
Common questions
What is a Cancer birth chart?
A birth chart is the whole sky at your birth: Sun, Moon, rising sign, all ten planets and the houses they fall in. "Cancer birth chart" usually means the chart of someone whose Sun is in Cancer — the Sun is one placement out of ten, so two Cancers can have very different charts.
Do all Cancers have the same chart?
No. They share the Sun in Cancer, and their Mercury is always in Gemini, Cancer, Leo, but the Moon can be in any of the twelve signs, the rising sign depends on birth time and place, and the outer planets depend on the year. The shared Sun explains why Cancers recognise each other; the rest explains why they are not interchangeable.
When does Cancer season start in 2026?
In 2026 the Sun enters Cancer on June 21 at 08:25 UTC and enters Leo on July 22. Across 1980–2030 the start falls on June 20 or 21 depending on the year, so people born on the boundary day should check the exact time.
Do I need my birth time?
For the Sun, Mercury, Venus and the outer planets, no. For the rising sign and houses, yes — they change every two hours or so. The Moon changes sign every two to three days, so a time helps on about one day in three. The free calculator works either way and tells you which parts depend on the time.
