How it works
Enter your birth date to see two zodiac systems at once. The Western zodiac is based purely on the month and day you were born (Aries, Taurus, Gemini, and so on), each sign mapped to a fixed date range, while the Chinese zodiac cycles through 12 animals based on your birth year alone (Rat, Ox, Tiger, and so on). Many people enjoy comparing both for a fuller astrological picture, since one depends on where in the year you were born and the other depends entirely on which year.
For example, someone born on June 15, 1995 falls in the Gemini range (May 21 to June 20) for their Western sign, and 1995 lands on Pig in the 12-year Chinese cycle. Because that cycle repeats every 12 years, anyone born in 1988, 2000, 2012, or 2024 shares the same Chinese zodiac animal as each other (Dragon, in that case), regardless of which month or day they were born.
Two cusp-related caveats worth knowing: the Western sign boundaries used here are the commonly cited fixed dates for each sign, but true astrological cusp dates can shift by a day depending on the year and the source, since they're tied to the sun's position rather than a fixed calendar rule. Separately, this calculator determines the Chinese zodiac purely from the Gregorian calendar year, while the traditional lunisolar calendar actually starts its new year between January 21 and February 20, so someone born in early January or early February may technically belong to the previous lunar year's animal under the traditional system.
Frequently asked questions
What zodiac signs are included?
Both the 12 Western zodiac signs, based on month and day, and the 12 Chinese zodiac animals, based on birth year, are shown together from a single date of birth.
Are the zodiac sign date ranges exact?
The Western sign boundaries used here are the commonly cited fixed dates, for example Gemini runs May 21 to June 20, but true cusp dates can shift by a day in either direction depending on the year and the astrological source. If your birthday falls right on a boundary date, you may see a different sign listed elsewhere.
Does the Chinese zodiac here use the exact Chinese New Year date?
No, it's simplified to use the Gregorian calendar year you were born in. The traditional Chinese lunisolar calendar starts each new year between January 21 and February 20, so someone born in that window technically may belong to the previous year's animal in the traditional system. For most birth dates outside that window, this calculator's result matches the traditional one.
How does the 12-year Chinese zodiac cycle work?
The 12 animals repeat in the same order every 12 years, so anyone born in 1988, 2000, 2012, or 2024, for example, shares the same animal. The calculator finds your animal by taking your birth year's position within that repeating 12-year cycle.
Can two people born on the same day have different zodiac signs?
Not for the Western sign, that's based purely on month and day, so it's the same for everyone born on a given date regardless of year. The Chinese zodiac animal, however, depends on the birth year, so two people born on the same month and day in different years can have completely different Chinese zodiac animals.
Is this based on real astrology or just for fun?
It's a straightforward date-based lookup for both systems, matching how these zodiac signs are conventionally defined, not a personalized astrological reading. The personality descriptions shown alongside each Western sign reflect commonly associated traits rather than a scientific assessment.
Which is more widely used, Western or Chinese zodiac?
Popularity varies by region: Western astrology, built around sun signs like Gemini or Leo, is more commonly referenced across the US and Europe, while the Chinese zodiac's 12-year animal cycle plays a bigger role in Lunar New Year traditions across East Asia. Neither is more "correct" than the other, they're simply two independent systems for describing the same birth date.
