How does the age calculator work?

Enter your date of birth and the calculator computes your exact age by comparing it to today's date (or any target date you choose). It accounts for leap years and gives results in years, months, days, hours, minutes and seconds.

Can I calculate the age between two specific dates?

Yes — you can set a custom target date instead of today to calculate age between any two dates.

What is the zodiac sign calculation based on?

Zodiac signs are based on Western astrology: Aries (Mar 21 – Apr 19), Taurus (Apr 20 – May 20), etc. The calculator automatically determines your sign from your date of birth.
