What is an Age Calculator?
An age calculator is an online tool that helps determine the precise difference between two dates. The most common use is to calculate your age from your date of birth to today’s date. But it also works in reverse helping you find how old someone was on a past date or how old they will be on a future date.
Many people also refer to this tool as a birthday calculator, since it’s often used to check upcoming birthday milestones or verify age for celebrations and legal requirements.
