Enter your date of birth to calculate your age.
The Age Calculator is a fast, free online tool that calculates your exact age based on your date of birth. Unlike simply subtracting your birth year from the current year, this calculator considers months and days to give you the most precise answer possible — down to the minute.
The calculator takes your date of birth and compares it to the current date and time. It then breaks down the difference into multiple units so you can see exactly how long you've been alive:
An age calculator is useful in many situations: filling out forms that require your exact age, calculating age for legal or medical purposes, tracking a baby's growth in weeks or months, comparing ages between family members, or simply satisfying curiosity about how many days you've been on this planet.
All calculations happen instantly in your browser. Your date of birth is never sent to any server and never stored. This tool is 100% private and works even without an internet connection once loaded.

Because a year has approximately 365.25 days (accounting for leap years). So 10 years is roughly 3,653 days, but your exact total depends on how many leap years occurred during your lifetime.
