Zodiac Signs by Month

Each month is a transition between two signs. Early-month birthdays usually belong to one sign; later in the month, the Sun crosses into the next. Cusp dates blur the boundary.

Zodiac Cusp Dates

If your birthday lands within a day or two of a sign change, you're on a cusp. Exact sign depends on the year and time of birth. See all 12 cusp windows:

Zodiac Calendar FAQ

What are the dates for all zodiac signs?

Aries runs March 21–April 19, Taurus April 20–May 20, Gemini May 21–June 20, Cancer June 21–July 22, Leo July 23–August 22, Virgo August 23–September 22, Libra September 23–October 22, Scorpio October 23–November 21, Sagittarius November 22–December 21, Capricorn December 22–January 19, Aquarius January 20–February 18, and Pisces February 19–March 20. Exact start and end times shift a day or two by year.

Do zodiac dates change every year?

The Sun moves through the zodiac on a precise astronomical schedule, so sign boundaries shift slightly each year — usually by a few hours, sometimes by a full calendar day. If you were born on March 20, April 19, May 20, or any other boundary day, your exact sign depends on both the year and the time of day.

What is a zodiac cusp?

A zodiac cusp is the narrow date range where the Sun crosses from one sign into the next. Astronomers treat this as an exact moment, but popular astrology often refers to cusp birthdays (like April 19–20, the Aries–Taurus cusp) as a blend of both signs' energies.

Which zodiac sign is my birthday?

Enter your birth date into the Zodiac Sign Calculator for an instant answer. If your birthday falls on a cusp (within one or two days of a sign change), we also show the exact sign for your year based on precise Sun ingress times from NASA ephemeris data.

What is the first sign of the zodiac?

Aries is traditionally the first sign of the zodiac. Aries season starts at the March equinox — the moment the Sun crosses the celestial equator heading north — and marks the beginning of the astrological year.
