May zodiac sign: Taurus or Gemini?
By Emily Hart, professional astrologer · updated September 7, 2026
The short answer
May is split between two zodiac signs: the Sun finishes its run through Taurus and enters Gemini around May 21. So your May zodiac sign depends on the day — and, if you're born right at the boundary, on the year and hour too.
Born around the boundary?
The Sun doesn't change signs at midnight sharp: the exact moment shifts by up to a day depending on the year and your time zone. If your birthday is May 20–21, don't guess — check your exact sign by date of birth.
What May people have in common
May is earth in bloom and air in motion: Taurus savors stability, Gemini savors change. What they share is appetite for life: May people know how to take pleasure from the world, be it taste, sound, touch or a good conversation.
Within each sign the flavor shifts by decan — ten-degree thirds of the sign. Born the 1st–9th, you're in the second decan of Taurus: its core with a shade of Virgo. The 10th–20th is the third decan, tinted by Capricorn. From the 21th you're in the first, purest decan of Gemini. That's why people of the same month, born ten days apart, can feel so different.
May's birthstone is the emerald: the stone of growth and renewal, traditionally given for luck in matters of the heart.
The Taurus in short
Taurus
April 20 – May 20
Tauruses build: steady, sensory, loyal across decades. They love through actions and refuse to be rushed — which is exactly why what they build lasts. In love they build slowly toward forever; Virgo, Capricorn and Cancer speak their language of presence and good dinners. Ruled by Venus, earth element: consistency is the courtship — rush nothing and receive everything.

Gemini
May 21 – June 20
Geminis run on curiosity: quick minds, double interests, conversation as oxygen. They learn everything and connect everyone — finishing things is the real quest. In love they fall for minds and stay for laughter; Libra, Aquarius and Aries keep the conversation alive. Ruled by Mercury, air element: bore them never, text them back, and the wit turns into devotion.

What zodiac sign is May?
May covers two signs: Taurus from the 1st through the 20th, and Gemini from the 21th through the 31th. The boundary day can shift by one day depending on the year — a birth chart settles it exactly.
What sign is May 21?
On the average year, May 21 is the first full day of Gemini — but in some years the Sun crosses the line a few hours earlier or later. If that's your birthday, the free calculator on our dates page resolves it from your exact date.
Why does May have two zodiac signs?
Zodiac signs follow the Sun's position, not the calendar: the Sun spends about 30 days in each sign, entering a new one around the 20th–23rd of every month. That's why every calendar month is shared by two signs.
Who are May-born people compatible with?
It depends which of the month's two signs is yours. Taurus is a Earth sign: it pairs most easily with its own element and its complement. Gemini runs on Air — a different circle entirely. The two sign cards above link to the full compatibility breakdown of each with all 12 signs; for a specific couple, a synastry of both full charts settles it.
