What Is My Zodiac Sign?

“What’s my zodiac sign?” is one of the most-searched personal questions on the internet — and the honest answer has nothing to do with fate. It’s a date lookup. Your Western zodiac sign comes from which of 12 fixed calendar windows your birthday falls in. Your Chinese zodiac sign comes from which lunar year — and which slot in a 60-year cycle of animal-element pairings — you were born into.

Plug your birth date into the calculator above and you’ll get both, instantly: your Western sign (Aries, Libra, Pisces, and so on) and your Chinese sign, an animal paired with an element, like Fire Tiger or Wood Dragon. Two calendars, two different logics, one birthday.

We compute the signs the way an almanac would — dates and cycles, nothing more. No horoscopes, no personality predictions. What the result means, if anything, is entirely up to you.

Two calendars, twelve signs each

The Western zodiac splits the calendar year into 12 unequal-length windows, each historically tied to a constellation the sun appeared to pass through — Aries first, Pisces last. The dates are fixed by the calendar, not by the stars’ current positions, which is why they haven’t shifted in centuries.

The Chinese zodiac runs on a longer clock: a 12-animal cycle (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig) paired with a 5-element cycle (Wood, Fire, Earth, Metal, Water), each element spanning two consecutive years. Multiply them out and you get 60 unique animal-element combinations before the cycle repeats — a Fire Tiger year like 1986 won’t come around again until 2046.

The catch: Chinese years start at Chinese New Year, which lands anywhere from late January to mid-February. Born in early January or early February? You may belong to the animal year before the one on your birth certificate.

How the calculator works

For the Western sign, the calculator checks your birth month and day against the 12 fixed tropical-zodiac ranges, from Aries (March 21–April 19) through Pisces (February 19–March 20). It’s a straight date lookup — no birth time or location needed.

For the Chinese sign, it maps your birth year to one of 12 animals on a repeating cycle, then layers on one of 5 elements based on the year’s last digit — years ending in 0/1 are Metal, 2/3 Water, 4/5 Wood, 6/7 Fire, 8/9 Earth. If you were born in January or early February, it checks whether your birthday falls before or after that year’s Chinese New Year date and adjusts the animal accordingly.

Limits: Chinese New Year’s exact date shifts every year, so the calculator relies on a lookup table of historical dates rather than a formula — accurate for real birthdates, but it can’t predict New Year dates centuries out.
