Age Calculator

Enter a birth date and this calculator returns the person's current age in completed years, correctly accounting for whether the birthday has already passed this year.

It is handy for forms, eligibility checks (voting, retirement, sports categories) and simple curiosity. Unlike dividing days by 365, this tool follows real calendar rules, so it is always exact — even around leap years and birthdays. To count the days between two specific dates instead, use the days between dates calculator.
