Age Calculator : Calculate Age in year, Month and day

An Age Calculator is a tool or application designed to calculate a person's age based on birth and current date. It determines the exact age in terms of years and often calculates months and days to provide more detailed information. Age Calculators are widely used for various purposes, including legal documentation, educational applications, health assessments, and simply for personal curiosity.

How It Works

To calculate age, the user inputs their date of birth into the calculator. The tool then uses the current date (usually obtained from the system clock or entered manually) to compute the age by subtracting the birth year from the current year. It may also adjust for the current month and day relative to the birth month and day to ensure accuracy, accounting for whether or not the birthday has occurred in the current year.
