Born on June 21
A cusp birthday. In most years the Sun crosses from Gemini into Cancer during June 21, so people born this day are one or the other depending on the hour. At noon UTC it's Cancer in 63% of years.
Gemini or Cancer? Check your year
The Sun's entry into Cancer shifts by a few hours from year to year. Find your birth year, convert your birth time to UTC, and compare: born before the time shown, you're Gemini; after it, Cancer. Years missing from the list had the crossing on a neighbouring day (the Sun was in one sign for the whole of June 21).

Your sign: Cancer (or Gemini)
The cardinal water sign that protects what it loves and remembers everything.
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.

Your decan: the first decan of Cancer
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 0–10 of Cancer belong to Venus: how you love, what you find beautiful, and what you value. Read it as Cancer with a Venus accent — the water core is unchanged, the emphasis moves.
Two of Cups
Partnership · Mutual attraction · Connection. The card assigned to this ten-degree slice of the zodiac — a birthday card in the same sense a sun sign is a birthday sign: one lens on the date, not a verdict.

The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Cancers born on June 21 in different years have different Moons; your rising sign changes every two hours and needs a birth time and place. Those two carry most of what people mean by "personality" in a chart.

Common questions
Is June 21 Gemini or Cancer?
Both are possible. On June 21 the Sun moves from Gemini into Cancer in most years, at a time that ranges from 00:56 UTC to 23:08 UTC UTC across 1980–2030 (in some years the crossing falls on the neighbouring day). Convert your birth time to UTC and compare it with the crossing for your year in the table above — before it you're Gemini, after it Cancer.
What zodiac sign is June 21?
June 21 is a cusp day between Gemini and Cancer; at noon UTC it falls in Cancer in 63% of years between 1980 and 2030. Your birth year and hour decide it.
What decan is June 21?
The first decan of Cancer (0°–10°), sub-ruled by Venus. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here how you love, what you find beautiful, and what you value.
What tarot card is June 21?
In the Golden Dawn system each decan has a minor arcana card: for the first decan of Cancer it is the Two of Cups (partnership, mutual attraction, connection). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on June 21 have the same chart?
No. They share the Sun in Cancer or Gemini, but the Moon changes sign every two to three days, the rising sign every two hours, and the outer planets by year. Two people born June 21 in different years can have almost nothing else in common in their charts.
