Age Calculator
Calculate your exact age in years, months, days — and even hours, minutes, and seconds.
About this calculator
The age computed represents the elapsed time between two dates. Months and days are rolled over based on calendar length, matching the most common age convention used in the U.S. and Europe.
How the Age Calculator Works
Enter your date of birth and choose any target date — today's date is selected by default. The calculator instantly breaks down the exact period into years, months, and days. It also shows the total span in weeks, days, hours, minutes, and seconds so you can see the full picture at a glance.
