An Age Calculator is a free online tool that works out your exact age based on your date of birth. Unlike a simple year subtraction, it breaks the result down into years, months, days, hours, minutes and seconds, and can also calculate your age as of any custom date — not just today.
This tool is useful for filling forms, academic records, job applications, eligibility checks and general personal curiosity.
Age is calculated as the difference between the reference date and the date of birth.
The raw difference is then converted into years, months and days, adjusting for varying month lengths and leap years.
