Understanding age calculations
Age is typically measured as the amount of time that has passed since a person's birth date. An accurate age calculation takes into account years, months and days rather than simply counting calendar years.
Why exact age matters
Exact age calculations are often required for legal documents, school registrations, insurance applications, retirement planning and medical records.
How this calculator works
Enter your birth date and the calculator compares it with today's date to determine your exact age in years, months and days.
