Frequently asked questions
How is my 12-year animal sign calculated?
Unlike basic calculators that just use the Gregorian year, our tool uses the precise Lunar New Year calendar. If you were born in January or February, your animal sign is calculated based on exactly when the Lunar New Year fell in your birth year, ensuring 100% accuracy.
How does this calculator handle leap years?
Our calculator strictly follows the Gregorian calendar for age. It automatically identifies leap years (years with 366 days like 2024, 2028) to ensure your 'Total Days' lived is mathematically perfect.
