When does Gemini start and end?

Gemini season begins on May 21 and ends on June 20. You may see the dates listed a day earlier or later on other sites, and that’s not an error — the Sun doesn’t change signs at the same clock time every year, so the exact start and end can shift by about a day depending on the year and your time zone. For almost everyone, the May 21 to June 20 range is exactly right. If your birthday lands on the very first or very last day, read the cusp section below.

Were you born on the Gemini cusp?

Born right at the edge of Gemini? Then you were born on a cusp — the changeover point between two signs. The first day of Gemini (May 21) sits on the Taurus–Gemini cusp, and the last day (June 20) sits on the Gemini–Cancer cusp. Astrologically there’s no such thing as being “half and half,” though — you are still fully one sign or the other. The only way to know for certain is to check the exact moment the Sun changed signs in your birth year, because a birthday on the boundary can fall under either sign depending on the year and the hour you were born. If you were born on May 21 or June 20, a quick birth-chart lookup will settle it for good.

The three decans of Gemini

Every sign is divided into three decans of roughly ten days, each with a sub-ruler that adds its own flavour to the core Gemini personality. Here’s where you fall:

  • First decan (May 21–31): the purest expression of Gemini, doubly ruled by Mercury — the most classic Gemini traits.
  • Second decan (June 1–10): shaded by Libra (sub-ruled by Venus), adding a Libra twist to your Gemini core.
  • Third decan (June 11–20): shaded by Aquarius (sub-ruled by Uranus and Saturn), adding an Aquarius twist to your Gemini core.

Gemini personality in brief

As a air mutable sign ruled by Mercury, Gemini is curious, quick-witted, and communicative — endlessly adaptable and social. That’s the short version — for the full breakdown of Gemini traits, strengths and weaknesses, love and compatibility, the Gemini man and woman, career, and mythology, read the complete Gemini zodiac sign guide.

Frequently asked questions

What are the Gemini horoscope dates?
Gemini covers birthdays from May 21 to June 20.

Is Gemini the sign for someone born on May 21?
Yes — May 21 is the first day of Gemini. Because it’s a cusp date, anyone born exactly on May 21 should double-check their birth year to be certain, but it falls under Gemini in most years.

What sign comes before and after Gemini?
Taurus (ends as Gemini begins) comes just before Gemini, and Cancer (begins as Gemini ends) comes just after.
