Age Calculator

Calculate exact age in years, months, days, hours and minutes from any birthdate.

Age Calculator tells you exactly how old someone is — not just in years, but in years, months, days, hours, minutes, and seconds — based on a birthdate you enter. The calculation respects the actual length of months and accounts for leap years, so the answer is precise to the day rather than a rough estimate. People use it to fill out forms that require exact age in months for childcare, immigration paperwork, school registration, and pediatric medical records. Parents use it to track milestones for newborns where each week matters. HR teams use it to confirm benefits eligibility around birthdays. Event planners use it to calculate ages for milestone birthdays. Genealogy researchers use it to verify ages in census records and historical documents. The tool runs locally in your browser, which means birthdates and personal information never get logged or transmitted.
