June 21 zodiac sign
June 21 is the classic cusp day: in most years the Sun leaves Gemini for Cancer at some point on this date, so the sign depends on birth year and time.
- Sun at 28°–30° Gemini
- 3rd decan · Saturn (modern: Uranus)
- Cusp birthday
June 21 in profile
Astrology has no in-between sign, so a June 21 birthday is either Gemini at its very last degree or Cancer at its very first; the computed table on this page settles which. The Gemini option is 29°, the anaretic degree, in the Aquarius decan of Saturn and modern Uranus: urgent, quick and full of the sign’s lessons at once. The Cancer option is 0°, cardinal water at its rawest, ruled by the Moon and doubly so in its first decan. Both share a sensitivity to the people nearby.
Generosity is strong either way. The Gemini version helps with words: an introduction, a CV rewritten overnight, a plan for the move. The Cancer version helps with food, a spare room and a lift to the airport at dawn. Many June 21 people do both, turning up with soup and a list of useful phone numbers. They notice need quickly and act before being asked.
Romantically they want conversation and closeness in the same relationship. A partner who is witty but distant leaves them hungry; one who is warm but silent leaves them restless. They show affection through attention to detail, remembering a partner’s favourite biscuit or the name of a difficult colleague. Learning to ask for care as readily as they give it is their real work.
Gemini or Cancer?
The Sun moves from Gemini into Cancer around June 21, and the exact moment shifts from year to year. Between 1930 and 2040 it happened during the UTC day of June 21 in 85 years out of 111, at a median of 13:01 UTC (11:45 UTC in births from 1980 to 2010). In 17 years the whole day was still Gemini. In 9 years it was already Cancer all day. So a June 21 birthday is Gemini or Cancer depending on the year and the time, never a blend of the two.
