Age calculations depend on the exact birth date and the date on which the calculation is made. A person born on a given calendar date reaches a new whole-year age on the anniversary of that date.
For legal, medical or official forms, use the date and calculation rules required by the relevant organization. An online calculator is useful for everyday planning, but official contexts may have specific definitions for age, eligibility or deadlines.
