Age Calculator

What it does

Age Calculator tells you exactly how old you are — not just a round number of years, but your precise age broken down into years, months, and days. Enter your date of birth and the tool does the rest: it calculates the total days you have lived, and counts down to your next birthday so you never miss it. Carbide runs all of this privately on your device, with no internet connection required, no sign-up, and no data ever leaving your phone or browser. It is completely free. Whether you need your exact age for a form, want to settle a friendly debate, or are simply curious how many days you have been alive, Age Calculator gives you the full picture at a glance.

How to use the Age Calculator

1. Tap the date of birth field and pick your birthdate from the date picker.
2. Carbide immediately displays your age in years, months, and days.
3. Check the total days lived and the countdown to your next birthday shown below the main result.

Frequently asked questions

How accurate is the age breakdown?

Very accurate. Carbide accounts for varying month lengths and leap years, so the years, months, and days figure is precise to today's date.

Can I calculate the age between two specific dates, not just up to today?

The current tool calculates age from your birthdate to today. For the difference between any two arbitrary dates, use the Date Difference tool.

Does the app store my date of birth?

No. Your birthdate stays only in the tool's input field for the current session. Nothing is stored or sent anywhere.

What does 'next birthday' show?

It shows how many days remain until your next birthday, so you always know exactly how long you have to wait.
