Calculate your exact age in years, months and days. Free age calculator.
Knowing your exact age down to the month and day is useful for more situations than you might expect. Legal documents, insurance applications, retirement planning, and medical assessments often require precise age information. This calculator determines your exact age in years, months, and days from your date of birth, accounting for varying month lengths and leap years. You can also set a custom target date to calculate your age at any point in the past or future, which is helpful for determining eligibility for programs, benefits, or milestones that depend on your age at a specific date.
Enter your date of birth and the calculator computes the difference between that date and today (or a custom target date you specify). It handles month-length variations (28 to 31 days) and leap years correctly. The result breaks down into complete years, remaining months, and remaining days. For example, if you were born on March 15, 1990, and today is April 21, 2026, you are 36 years, 1 month, and 6 days old.
