🎂 Age Calculator
Pop in your birth date and get your exact age — down to the day. No more "uhh I think I'm 24?"
What this tool actually does
This calculator works out the exact time between your birth date and today (or any date you choose) — broken down into full years, months, and days, the same way you'd count it on a calendar. It also shows extra fun stats like total days lived and roughly how many times your heart has beaten.
It runs entirely in your browser, so your birth date is never sent anywhere or stored. Close the tab and it's gone.
Frequently asked questions
How is age calculated exactly?
Your age is worked out by counting the full years, months, and days between your birth date and the comparison date, accounting for different month lengths and leap years — not just a rough estimate.
Why doesn't my age in months match a simple division?
Months vary in length (28 to 31 days), so the calculator counts actual whole months passed since your last birthday, then adds the remaining days — giving you a precise figure instead of an approximation.
Does this account for leap years?
Yes — since the calculation is based on real calendar dates, leap years are automatically factored in with no extra steps needed.
