This calculator compares the entered birth date with today's date and displays an age in years, months and days. The current calculation uses a simplified 30-day adjustment when the birth day is later in the month; it is not a precise calendar-age method for every date. Use the result for informal planning or a quick birthday estimate. For school admission cut-offs, employment forms, pension eligibility or any rule tied to age on a specified date, verify the calculation against an actual calendar or the relevant authority.
