What zodiac sign is June 21?

If you were born on June 21, your Sun sign is technically Gemini — but only just. The Sun usually moves into Cancer on June 21, though the exact date and time shift slightly each year. This means you could be a Gemini with a deeply Cancerian flavor, or a true Cancer if you were born later in the day. In astrological terms, you were born on the Gemini-Cancer cusp, a threshold often called the "Cusp of Magic." People born here tend to carry the quick, curious mind of Gemini alongside the tender, protective heart of Cancer. Your natal chart will show the Sun at the very last degree of Gemini or the very first degree of Cancer, and that precise placement matters. Gemini energy is airy, verbal, and scattered — it wants to learn everything. Cancer energy is watery, intuitive, and nesting — it wants to feel everything. When these two meet in one person, you often get someone who is both witty and deeply sentimental, a natural storyteller with a rich inner world. Mercury rules Gemini, while the Moon rules Cancer, so your chart ruler depends entirely on your exact birth time and place. This is a symbolic framework for self-reflection, not a scientific fact.
