Zodiac sign calculator
Enter a date of birth to find its Western zodiac sign (based on the tropical zodiac of 12 signs) as well as its Chinese zodiac sign. A simple calendar calculation, performed locally in your browser.
How it works
The Western (or "tropical") zodiac divides the year into 12 fixed periods of about one month, each associated with a sign and an element (Fire, Earth, Air or Water). This tool simply compares the day and month you enter against the official date ranges of each sign to determine which one applies, and also calculates the Chinese zodiac sign from the year of birth on a 12-year cycle.
Why is the Chinese sign approximate?
Chinese New Year follows the lunar calendar and falls on a different date every year (between late January and mid-February), whereas this calculator uses the full calendar year to keep the calculation simple. If your date of birth is in January or early February, the actual Chinese sign may therefore differ from the one shown here by one position.
What does the element associated with a sign mean?
In the Western astrological tradition, the 12 signs are divided into 4 groups of 3 signs sharing the same element (Fire, Earth, Air, Water), supposed to reflect a common temperament. This is a traditional, cultural classification with no demonstrated scientific value.
No date of birth is sent to a server: the calculation happens entirely in your browser.
