How to calculate your age with our age calculator ?
To calculate age, you need to know the person's birth date and the current date. The calculation considers the number of full years between the birth date and the current date. Here's how you can calculate age in years:
 Subtract the birth year from the current year:
 Current Year  Birth Year = Age in Years
For example, if someone was born in 1990 and the current year is 2024:
 2024 (Current Year)  1990 (Birth Year) = 34 (Age in Years)

 Adjust the age if the birthday has not occurred yet this year:
 If the birth month and day have not occurred yet this year, subtract 1 from the result to get the correct age.
For example, if the birth date is February 15, 1990, and the current date is February 28, 2024:
 Age in Years = 2024  1990 = 34 (years)
 Since the birthday has not occurred yet this year, the correct age is 33 (years).
This method provides a precise calculation of a person's age in years. If you need to calculate age in months or days as well, you can use a similar approach, considering the birth month and day in relation to the current month and day.
