How to Use the Age Calculator

Step 1: Enter Your Date of Birth

Select your day, month, and year using the Date of Birth fields at the top of the calculator. The month appears as a name like January or March, and the year can be entered from 1000 to 9999. If you know your exact birth time, you can add it in the optional Time of Birth field for more precise results.
