**Age Calculator – Online Age Calculation**

A tool that determines a person’s age based on their date of birth is called an age calculator. The user inputs their birthdate into the calculator, which then computes their age using the current date. The outcome is then presented to the user.

To calculate age, the calculator subtracts the user’s birth year from the current year. If the user has not yet celebrated their birthday for the current year, the age is adjusted by subtracting 1 from the computed age. For instance, if the current year is 2023 and the user was born on March 20, 1990, their age would be 33 since they haven’t celebrated their birthday yet.

An age calculator can be beneficial in various situations, such as when a person requires to establish their age for legal or medical reasons, or when planning for retirement. It can also be enjoyable for individuals to determine their age or that of their loved ones. Age calculators can be found online as separate tools or incorporated into other websites or applications.
