Age Calculator

Calculate your exact age in years, months, and days.

How It Works

The calculator subtracts your date of birth from today’s date. It accounts for leap years, varying month lengths, and adjusts for negative values in days or months. This ensures the result is precise. For example, if you were born on March 15, 1999, and today is November 25, 2025, the calculator shows 26 years, 8 months, and 10 days.
