Zodiac Calculator

Western astrology divides the year into 12 sun signs based on the position of the Sun at the moment of birth. Each sign spans roughly 30 days and is associated with one of four elements (Fire, Earth, Air, Water) and a ruling planet. Chinese astrology uses a 12-year cycle of animals — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig — where the year of birth determines your sign. Each Chinese zodiac year is also linked to one of five elements (Wood, Fire, Earth, Metal, Water) on a 60-year cycle. This calculator gives you both systems instantly from a single birth date.

lightbulb Quick Facts

  • •Western: 4 elements — Fire, Earth, Air, Water
  • •Chinese: 5 elements — Wood, Fire, Earth, Metal, Water
  • •Born in Jan/Feb? Your Chinese sign may be from prior year
  • •Chinese zodiac repeats every 12 years
  • •Full Chinese cycle (animal + element) = 60 years

The Formula

The Western zodiac boundary dates are fixed by the Sun's ecliptic position (approximately the same calendar date each year with ±1 day variation). The Chinese zodiac year officially starts on Chinese New Year (late January to mid-February) — this calculator uses January 1 as a simplification; if born in January or early February, your Chinese sign may be from the previous year.

Western: month/day → sign boundary lookup | Chinese: (year − 4) % 12 → animal index

lightbulb Variables Explained

tips_and_updates Pro Tips

1

If born near a sign boundary (cusp), you may feel traits of both neighboring signs.

2

Chinese New Year shifts between Jan 21 and Feb 20 — if born in January or early February, check if your sign is from the prior year.

3

Your Chinese zodiac element changes every 2 years, cycling through Wood, Fire, Earth, Metal, Water over 10 years.

4

Western 'cusp' dates vary by ±1 day due to leap years — use birth time for maximum precision.

5

The Chinese zodiac repeats every 12 years: 2024=Dragon, 2025=Snake, 2026=Horse.

Zodiac signs are determined by the position of the Sun relative to twelve constellations along the ecliptic at the time of your birth. Each sign spans approximately 30 degrees of the celestial longitude and covers roughly one month of the calendar year, though exact dates shift slightly each year due to the precession of equinoxes. Western astrology uses the tropical zodiac (based on seasons and equinoxes), while Vedic astrology uses the sidereal zodiac (based on actual constellation positions), which currently differs by approximately 24 degrees — meaning your Western and Vedic signs may differ. Our zodiac calculator determines your Sun sign from your birth date, displays the associated element (fire, earth, air, water), modality (cardinal, fixed, mutable), ruling planet, and date range. It also identifies your Chinese zodiac animal based on birth year and provides compatibility insights with other signs.

The twelve zodiac signs and their dates

The Western zodiac signs and approximate date ranges: Aries (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). People born on the boundary between two signs (within 1-2 days of the transition) are said to be born on the cusp and may identify with traits of both signs. The exact transition moment varies by year and requires the Sun's precise ecliptic longitude for that specific date and time.

Elements and modalities in astrology

The twelve signs are grouped into four elements: Fire signs (Aries, Leo, Sagittarius) are associated with energy, enthusiasm, and initiative. Earth signs (Taurus, Virgo, Capricorn) are linked to practicality, stability, and material concerns. Air signs (Gemini, Libra, Aquarius) represent intellect, communication, and social connection. Water signs (Cancer, Scorpio, Pisces) are connected to emotion, intuition, and sensitivity. Three modalities further categorize the signs: Cardinal signs (Aries, Cancer, Libra, Capricorn) initiate action and correspond to the start of each season. Fixed signs (Taurus, Leo, Scorpio, Aquarius) represent stability and determination during mid-season. Mutable signs (Gemini, Virgo, Sagittarius, Pisces) are adaptable and mark seasonal transitions.

Chinese zodiac and compatibility

The Chinese zodiac follows a 12-year cycle, with each year assigned an animal: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. Unlike Western astrology's monthly cycle, your Chinese zodiac animal is determined by birth year (with New Year falling between January 21 and February 20, varying annually). 2024 is the Year of the Dragon, 2025 the Snake, and 2026 the Horse. Traditional compatibility groupings form four trines: Rat-Dragon-Monkey (ambitious, competitive), Ox-Snake-Rooster (determined, thoughtful), Tiger-Horse-Dog (idealistic, independent), and Rabbit-Goat-Pig (compassionate, creative). Signs within the same trine are considered most compatible. The six clashing pairs (Rat-Horse, Ox-Goat, Tiger-Monkey, Rabbit-Rooster, Dragon-Dog, Snake-Pig) are traditionally considered the most challenging combinations.
