Calculate your exact age in years, months, and days from your date of birth.
Enter your date of birth using the date picker.
Click "Calculate" to see your exact age broken down into years, months, and days.
The calculation uses today's date as the reference point and accounts for leap years and varying month lengths.
The age is computed by finding the difference between today's date and the birth date:
Age = Current Date − Birth Date
Years, months, and days are calculated sequentially, accounting for different month lengths (28-31 days) and leap years (every 4 years, except centuries not divisible by 400).
Example: Born on July 15, 1990, calculated on March 30, 2026.
Yes. The calculation properly handles leap years, including the rule that century years must be divisible by 400 to be leap years (e.g., 2000 was a leap year, but 1900 was not).
The calculator uses your device's local date. If you need exact precision for legal purposes (such as calculating the age of majority), consult official records.
Yes. Simply enter any date of birth, and the calculator will determine the exact age as of today.
