Frequently Asked Questions

How is the exact age calculated? The calculator accounts for varying month lengths. If you were born on January 31 and today is March 2, you’re 1 month and 2 days old (not 1 month and 1 day).

Are the zodiac signs accurate? Western zodiac is based on standard date ranges. Chinese zodiac uses the Gregorian year (the traditional lunar calendar dates may differ slightly).

What’s the oldest date I can enter? Any valid date in the past. The calculator works with JavaScript’s Date object, which supports dates far into the past.
