A fast, private zodiac sign calculator

If you have ever asked yourself, "what is my zodiac sign?", this tool provides an instant and comprehensive answer. By simply entering your date of birth, you can discover both your Western astrological sign and your Chinese zodiac animal in one place.

Because the tool runs entirely locally in your web browser, your personal information is completely secure. Your birth date is never uploaded to a server, saved, or tracked. You can check dates for yourself, your friends, or your family members with total peace of mind.

Discover your star sign by birthday

The Western zodiac is based on the path of the sun across the sky over the course of the year, divided into twelve distinct sectors. Finding your star sign by birthday helps you identify which of these twelve signs the sun was in when you were born.

When you select your birth date, the calculator instantly displays your Western zodiac sign alongside its traditional symbol. It also shows the standard horoscope sign dates for your specific sign. This is particularly helpful if you want to know exactly when your sign begins and ends during the year.

Alongside your sign, the tool reveals your classical element. The Western zodiac categorizes all twelve signs into four elements:

  • Fire (Aries, Leo, Sagittarius)
  • Earth (Taurus, Virgo, Capricorn)
  • Air (Gemini, Libra, Aquarius)
  • Water (Cancer, Scorpio, Pisces)

Accurate Chinese zodiac calculator

While the Western zodiac is tied to the solar calendar, the Chinese zodiac operates on a lunisolar calendar. This system features a twelve-year cycle, with each year represented by a specific animal.

Determining your Chinese zodiac animal by year is usually straightforward for those born in the middle or end of the year. However, because the Lunar New Year falls on a different date every year—typically between January 21 and February 20—people born in January or February often get the wrong result from basic calculators.

This tool functions as a highly accurate Chinese zodiac calculator by automatically adjusting for the exact date of the Lunar New Year. If you were born in early February, but the Lunar New Year didn't start until mid-February that year, the calculator will correctly assign you the animal from the previous Gregorian year. When this happens, a small notice will appear letting you know that your birth date fell before the Lunar New Year, ensuring there is no confusion about why your animal might differ from the standard calendar year.

Understanding the elements

Just as the Western zodiac uses four classical elements, the Chinese zodiac incorporates its own elemental system known as Wu Xing. This system consists of Five Elements: Wood, Fire, Earth, Metal, and Water.

In Chinese astrology, these elements cycle alongside the twelve animal signs, creating a 60-year combination cycle (for example, the Year of the Water Dragon or the Year of the Wood Rabbit). Our calculator automatically determines your specific Wu Xing element based on your lunar birth year, giving you a more complete picture of your astrological profile.

Frequently asked questions

What is my zodiac sign if I was born on a cusp?
If your birthday falls on the transition day between two signs (a cusp), your exact sign can sometimes depend on the specific time and year of birth. This calculator uses standard horoscope sign dates to determine your primary sign.
Why does my Chinese zodiac animal differ from my birth year?
The Chinese zodiac is based on the lunar calendar, which starts on a different date each year, usually between late January and mid-February. If you were born before the Lunar New Year, your Chinese zodiac animal actually belongs to the previous Gregorian year.
Is my birth date saved or shared?
No. This zodiac sign calculator runs entirely in your web browser. Your birthday is never uploaded to any server or stored in any database, ensuring complete privacy.
What are the elements shown in the results?
The Western zodiac uses four classical elements (Fire, Earth, Air, Water). The Chinese zodiac uses Wu Xing, or the Five Elements (Wood, Fire, Earth, Metal, Water), which cycle alongside the animal signs.
What date range does this calculator support?
You can calculate signs for any birth date between January 1, 1902, and December 31, 2099.
