Free Online Age Calculator
Work out an exact age in years, months, weeks and days between any two dates.
There are plenty of moments when you need a precise age rather than a rough one — a form that asks for age in completed years, curiosity about how many days old you are, or working out how far apart two dates fall. Enter a birth date and, if you like, a second date to measure to, and this calculator breaks the gap down into years, months, weeks and days, handling leap years and month lengths correctly.

Why Use TextsPro
The calculation runs in your browser, so the dates you enter are never uploaded or stored. That keeps a birth date — which is genuinely personal information — off any server and entirely on your device. Because there is no network request, results appear the instant you enter a date, and the tool is free to use as often as you like with no account. It correctly accounts for leap years and varying month lengths, so the day count is accurate rather than approximate.
