Calendar fact

Born near the Taurus–Gemini boundary?

A sign starts the moment the Sun reaches its position on the ecliptic, not at midnight on a fixed calendar date. Because the tropical year is about 365.2422 days long, that moment moves by up to about a day from one year to the next and resets with the leap-year cycle. This is why reputable tables list a sign as beginning on, for example, 20 or 21 March and both are correct for different years.

How the two boundaries around Gemini behave, and what decides a borderline birthday.
Boundary	Dates it can fall on	What decides it
Taurus Gemini	May 20 or May 21	The birth year, then the birth time and time zoneNot resolvable from a date table alone
Gemini Cancer	June 20 or June 21	The birth year, then the birth time and time zoneSame drift applies at both ends

How to read this: if a birthday falls squarely inside May 21 - June 20, the sign is Gemini in every year. If it falls on May 20, May 21, June 20 or June 21, a published table cannot answer it and this site does not pretend otherwise. This site uses the conventional ranges for a month-and-day lookup and does not compute the Sun's exact position, which is what an ephemeris-backed natal chart does.

Frequently Asked Questions

What are the conventional Gemini dates?▼

Gemini is commonly assigned to May 21 - June 20 in the tropical zodiac. Boundary dates can vary by source, and a full natal chart uses year, time, and location.

Am I Gemini or Taurus if I was born on May 20?▼

It depends on the year. Gemini begins the moment the Sun reaches its point on the ecliptic, and that moment shifts by up to about a day across the leap-year cycle, so May 20 falls in Taurus in some years and Gemini in others. A table cannot settle it; the birth year, and strictly the birth time and time zone, are needed.

Is there really a Taurus–Gemini cusp sign?▼

No. In astrological tradition the Sun occupies exactly one sign at any moment, so there is no thirteenth "cusp" sign. "Cusp" is popular shorthand for a birthday close to a boundary, where the published date alone is not decisive.

What are the Gemini element and modality?▼

Gemini is classified as a Air sign with a Mutable modality in Western astrological tradition.

Are Gemini personality and compatibility readings scientific?▼

No. They are interpretations within astrology, not scientific measurements or reliable predictions about personality, relationships, career, or future events.
