More than just completed years.
Exact age is the calendar difference between a date of birth and a selected target date. It includes completed years, remaining months and remaining days, making it useful for applications, eligibility checks, school admissions, insurance and personal milestones.
Why calendar-aware calculation matters
Months have different lengths and leap years add an extra day. This calculator works with real dates instead of approximating every month as 30 days.
Age on another date
You can choose a past or future target date to find how old you were—or will be—on a specific day.
