Quick Answer
To calculate your age, subtract your birth date from today. Your exact age is the difference in complete years, remaining months, and remaining days. For example, if born January 15, 1990, and today is December 9, 2025, you are 35 years, 10 months, and 24 days old. Our calculator instantly computes your age in years, months, days, weeks, hours, and even seconds.
