Age Calculator — free online tool
Parents planning school admission, HR teams verifying eligibility dates, and anyone filling forms that ask “age as of today” get years, months, and days from a single birthday field.
Cross-check anything that affects money or health with a qualified professional or official source.
How to use Age Calculator
- Pick your date of birth with the calendar control on the Age Calculator.
- Optionally change the “as of” date if you need age on a past or future day.
- Press calculate to see years, months, and days between the two dates.
- Note the breakdown for forms that ask for exact age rather than whole years only.
Practical tips
- For school or visa forms, note whether they want age "as of today" or "as of" a specific cut-off date.
- The months and days breakdown matters for infants and pension eligibility, not just whole years.
- Time zones do not shift a date of birth—enter the calendar date as written on the document.
Limitations
Age Calculator uses simplified formulas. Tax brackets, bank rounding, leap seconds, and regional holidays are not modelled—confirm important totals with an official calculator or advisor.
