Calculate your age in years, months, and days from your date of birth.
Age is a fundamental concept used to measure the duration of an individual's life. The most common way to calculate a person's age is to subtract the year of their birth from the current year. However, a more precise calculation must also account for the month and day of birth to determine if the person has already had their birthday in the current year.
The Formula:
The basic formula for age calculation is straightforward: Age = CurrentYear - BirthYear To get a more accurate result, you check if the current date is before the birth date in the current year. If it is, you subtract one from the result of the initial calculation.
Note: This tool provides an age calculation based on the year. For an exact age in months and days, additional logic would be required to account for the number of days in each month and leap years.
