About the Age Calculator
What Is an Age Calculator?
An age calculator is an online tool that determines the amount of time between a person's date of birth and a selected calculation date. It can provide an age in years and, depending on the calculator, additional months and days.
How Is Age Calculated?
Age is calculated by comparing the date of birth with another date. The calculator accounts for the different numbers of days in months and the passage of calendar years to determine the elapsed age.
Why Calculate Your Exact Age?
Knowing your exact age can be useful when planning birthdays, checking eligibility requirements, comparing ages, preparing forms, or simply understanding the exact amount of time that has passed since your birth date.
How the Age Calculator Works
Enter your date of birth and allow the calculator to compare it with the current date or another selected date. The tool processes the calendar difference and displays the calculated age.
Calculate Age for a Specific Date
A date-based age calculator can also be useful when you want to know how old someone will be on a future date or how old they were on a date in the past.
