What is an age calculator?

Yes. Set “Age at the date of” to any day on or after the date of birth — useful for forms, eligibility checks, and milestones.
Does the Age Calculator show years, months, and days?
Yes. You get an exact breakdown in years, months, and days, plus totals in weeks, days, hours, minutes, and seconds, and a next-birthday countdown.
Is my date of birth stored?
No. Age is calculated entirely in your browser. Nothing is uploaded or saved on our servers.
