Use this calculator for someone's age on a chosen day: a birthday, a form, or a milestone.
Age is counted on the calendar, not as total days divided by 365. From 15 June 1990 to 28 August 2026 that is 36 years, 2 months, and 13 days. Korean age and lunar calendars are different systems on purpose.
Birth date: Date of birth.
As of: The day you want the age on, often today.
Years, months, days: Completed years, then leftover months, then leftover days.
Total days: The inclusive day count between the two dates.
