Calendar fact

Born near the Virgo–Libra 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 Libra behave, and what decides a borderline birthday.
Boundary	Dates it can fall on	What decides it
Virgo Libra	September 22 or September 23	The birth year, then the birth time and time zoneNot resolvable from a date table alone
Libra Scorpio	October 22 or October 23	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 September 23 - October 22, the sign is Libra in every year. If it falls on September 22, September 23, October 22 or October 23, 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 Libra dates?▼

Libra is commonly assigned to September 23 - October 22 in the tropical zodiac. Boundary dates can vary by source, and a full natal chart uses year, time, and location.

Am I Libra or Virgo if I was born on September 22?▼

It depends on the year. Libra 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 September 22 falls in Virgo in some years and Libra in others. A table cannot settle it; the birth year, and strictly the birth time and time zone, are needed.

Is there really a Virgo–Libra 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 Libra element and modality?▼

Libra is classified as a Air sign with a Cardinal modality in Western astrological tradition.

Are Libra personality and compatibility readings scientific?▼

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