The Age Calculator gives a clear age result from a selected date of birth. It can be used for forms, records, eligibility checks, planning, and everyday date calculations.
How to Use Age Calculator
- Enter the date of birth as YYYY-MM-DD or tap the calendar icon.
- Optionally enter a target date, or leave it as today.
- Calculate or let the filled date refresh the result.
- Review age totals, next birthday, zodiac details, and copy the summary.
Calculate exact age
Age is often needed in years, months, and days rather than only a total number of years. This calculator compares the birth date with today or a custom date and returns a readable result with total days, total weeks, next birthday timing, weekday born, zodiac details, and a copyable summary.
How age is calculated
The calculator compares calendar dates and adjusts months and days when the target day or month has not yet been reached.
More than years and months
The result includes total weeks, hours, minutes, seconds, the weekday born, next birthday timing, and zodiac details for quick sharing.
Typed dates on mobile
The visible field accepts YYYY-MM-DD typing while the calendar icon still opens the native picker where supported.
