How accurate is the age calculation?

The calculator uses JavaScript's Date API for exact calculations, accounting for leap years, different month lengths, and daylight saving time.

Western zodiac signs are determined by the month and day of birth, regardless of the year.

The calculator uses your local date. If born in a different time zone, select your actual local date of birth.

Find your exact age in years, months, days, hours, and minutes. Browser-based, no signup.
