Age Calculator — Calculate Exact Age & Date Intervals
Determine your exact age or calculate the precise time interval between any two dates. Our online Age Calculator computes the duration down to years, months, weeks, days, and even minutes, and displays the exact time remaining until your next birthday. It is highly useful for filling out application forms, calculating retirement eligibility, checking milestones, or counting down to special events. Since all date calculations are done on your machine via JavaScript, your birth dates are never stored, tracked, or sent across the network.
