Frequently Asked Questions
How is my Western zodiac sign determined?
Your sign depends only on your birth month and day, not the year. Each sign covers a fixed date range, for example Aries runs from March 21 to April 19. The calculator matches your birthday against all 12 ranges, including the Capricorn range that wraps across the year boundary from December 22 to January 19.
How does the Chinese zodiac work?
The Chinese zodiac follows a 12-year cycle of animals (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig) combined with a 10-year cycle of five elements (Wood, Fire, Earth, Metal, Water), giving a 60-year full cycle. The year is determined by Chinese New Year, which falls between late January and mid-February.
Why might my Chinese zodiac be wrong for a January or February birthday?
The Chinese zodiac year switches at Chinese New Year, whose Gregorian date shifts every year between about January 21 and February 20. This tool approximates the boundary as February 4. If you were born in January or early February, check the exact Chinese New Year date of your birth year to confirm your animal.
Is my zodiac sign the same as my sun sign?
Yes. In Western astrology the sign most people mean by "my sign" is the sun sign, the sign the sun occupied at your birth. Full birth charts also include a moon sign and rising sign, which depend on birth time and location and are beyond this tool scope.
Does this tool store or upload my birthdate?
No. All calculations run entirely in your browser. Your birthdate never leaves your device, and the page works offline once loaded.
