What's the difference between a May vs June Gemini?

All Geminis (born between May 21 and June 20) are known for being curious, interesting, and easy communicators. However, May Geminis are sometimes believed to be friendlier, more easy-going, and more likely to live in the present moment, while June Geminis may be more intense and less likely to let things roll off their back.

Gemini is symbolized by the Twins, and some jokingly say May Gemini is the "good twin" while June Gemini is the "bad twin," but there is really nothing "bad" about June Gems: they may just be a little more hardcore and willing to walk away from what doesn't serve them than their May counterparts.

Looking at the zodiac as a color wheel has helped me immensely! If every sign is a color, I visualize a gradient between the previous sign and the next. A May Gemini may have some shades of Taurus behavior, while a June Gemini may lean toward watery, Cancerian traits. In this case, the reliable and stable Taurus may fit others’ definition of “good” and an air sign more in touch with their emotional expression may be seen as less tolerant. It’s all perspective!

In astrology, each sign is divided into three sections called decanates, or decans. These are roughly 10-day segments co-ruled by another planet of the same element. For Geminis, the early ones born in May tend to be more stereotypical Geminis—spontaneous, curious, and quick-witted. June Geminis, on the other hand, might have influences from other air signs like Libra or Aquarius, which can make them more idealistic or flirty. You might also see Venus or Saturn influences depending on where their birthday falls, so they could lean into those traits. In my opinion, decans are really the main reason for differences between people of the same sign. The idea of May vs. June is related, but decans break it down in a more accurate way—every 10 days. The May/June question is common, but the differences are really based on these smaller divisions. Finally, the rest of your chart makes a big difference too. Your sun sign is only one small part of your astrological makeup.
