How exact age is calculated

Age is computed calendar-accurately — borrowing days from the previous month and months from the previous year when needed — so it matches how ages are used on official forms, rather than a rough "divide by 365" estimate. Leap years are handled automatically.

Age as of a specific date

Use the "Age as of" field to compute age on any date — handy for exam eligibility cut-offs, visa applications, school admissions, and retirement dates that require your exact age on a given day.
