How Age Is Calculated

Age is calculated as the number of complete years from your birth date to today. If this year’s birthday has passed, age equals current year minus birth year; otherwise subtract one more.

This calculator also shows total days lived, months elapsed, and days remaining until your next birthday. Leap years are automatically accounted for.
