How is Age Calculated?
Different cultures and systems calculate age differently. For example, a person who is 20 years old in the international age system might be 1 or 2 years older in Chinese or Korean age systems.
Under the international age system, age is generally calculated in two ways:
- In Years: Each year is considered to have 365 days, without distinguishing between regular and leap years.
- In Days: The calculation accounts for months with 30, 31, 28, or 29 days and includes both 365-day and 366-day leap years accordingly.
For example, if you were born on January 5, 2000, and today is May 1, 2024, the calculator determines your age in days using the formula:
Age in days = (Years with 365 days) + (Years with 366 days) + (Days in the current year)
Limitations of the Calculator

Age results may differ slightly based on leap years and the method used for calculation.
