⭐ Zodiac Sign Calculator

Your zodiac sign (also called sun sign or star sign) is determined by your birth date. Enter your birthday above to find out! There are 12 zodiac signs, each covering approximately one month. Your sign reveals personality traits, compatibility, and characteristics according to astrology.

Simply enter your birth month and day in our calculator above. Your zodiac sign is based on the sun's position at your birth. For example: born March 25 = Aries, born July 15 = Cancer, born December 1 = Sagittarius. The dates for each sign are consistent year to year.

Here are all zodiac sign dates: Aries (Mar 21-Apr 19), Taurus (Apr 20-May 20), Gemini (May 21-Jun 20), Cancer (Jun 21-Jul 22), Leo (Jul 23-Aug 22), Virgo (Aug 23-Sep 22), Libra (Sep 23-Oct 22), Scorpio (Oct 23-Nov 21), Sagittarius (Nov 22-Dec 21), Capricorn (Dec 22-Jan 19), Aquarius (Jan 20-Feb 18), Pisces (Feb 19-Mar 20).

October has two zodiac signs: Libra (September 23 - October 22) and Scorpio (October 23 - November 21). If you're born October 1-22, you're a Libra. If you're born October 23-31, you're a Scorpio.

January spans two signs: Capricorn (December 22 - January 19) and Aquarius (January 20 - February 18). Born January 1-19? You're a Capricorn. Born January 20-31? You're an Aquarius.

February includes Aquarius (January 20 - February 18) and Pisces (February 19 - March 20). Most of February is Aquarius, with Pisces starting around the 19th.

There are 12 zodiac signs in Western astrology: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Each sign spans roughly 30 days and corresponds to a constellation. The Chinese zodiac has a different system with 12 animal signs.

Your zodiac sign is believed to influence your personality, strengths, weaknesses, and compatibility with others. Each sign has associated traits - for example, Leos are often confident and creative, while Virgos tend to be analytical and detail-oriented. Your element (Fire, Earth, Air, Water) also shapes characteristics.

The 12 signs are grouped into 4 elements: Fire (Aries, Leo, Sagittarius) - passionate, energetic, bold. Earth (Taurus, Virgo, Capricorn) - practical, grounded, reliable. Air (Gemini, Libra, Aquarius) - intellectual, social, communicative. Water (Cancer, Scorpio, Pisces) - emotional, intuitive, empathetic.

Your sun sign is the same as your zodiac sign - it's determined by the sun's position at your birth. In astrology, the sun represents your core identity, ego, and conscious self. When someone asks "what's your sign?", they mean your sun sign. Our calculator finds this based on your birthday.

There's no "best" sign - each has unique strengths! Leos are natural leaders, Virgos excel at details, Pisces are creative, Capricorns are determined. What matters is understanding your sign's traits and using them positively. Compatibility also depends on individual charts, not just sun signs.

Compatible signs often share the same element or complement each other: Fire signs match well with Air signs (Aries+Gemini, Leo+Libra). Earth signs pair with Water signs (Taurus+Cancer, Virgo+Scorpio). However, any signs CAN be compatible - it depends on the full birth chart, not just sun signs!

Compatibility is based on element harmony and sign positions. Signs of the same element understand each other naturally. Opposite signs (like Cancer-Capricorn) can attract or clash. Signs that are 4 positions apart (trine) are highly compatible. Full compatibility requires comparing complete birth charts.

Horoscopes are for entertainment and self-reflection. While many find meaning in astrology, there's no scientific evidence that celestial positions affect personality or predict the future. Sun sign horoscopes are very general - professional astrologers use complete birth charts for personalized readings.

The Western zodiac originated in ancient Babylon around 2,000 BCE and was refined by the Greeks. The 12 signs correspond to constellations along the ecliptic (sun's apparent path). The word "zodiac" comes from Greek "zōidiakos kyklos" meaning "circle of animals." It's been used for millennia across cultures.

A "cusp" is when you're born near the transition between signs (within ~3 days). You have ONE sun sign based on the exact date, but you may relate to both signs' traits. For precise cusp determination, the exact time and year matter. Our calculator gives your primary sign based on standard dates.

No, your zodiac sign never changes - it's fixed by your birth date. There were rumors about a "13th sign" (Ophiuchus) affecting signs, but Western astrology uses the tropical zodiac based on seasons, not constellations. Your sign today is the same as when you were born.

The Chinese zodiac is a different system with 12 animal signs based on birth YEAR, not month: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig. Each animal year cycles every 12 years. This calculator shows Western zodiac signs; Chinese zodiac requires your birth year.
