Age Calculator — years & months
Find out exactly how old you are – down to the day. No guesswork, just your real age in years, months, and days.

Why you'll love this tool
Unlike basic calculators that just subtract years, this one respects the real calendar. It knows that February has 28 or 29 days, that months are different lengths, and that leap years actually matter. So if you were born on March 30 and today is February 28 (non‑leap), it won't tell you that you're one month older — it gives you the exact days.
Whether you're filling out a form, planning a milestone birthday, or just curious, this tool gives you the precise answer in a warm, friendly format. No sign‑up, no data tracking — it all runs privately in your browser.
📝 How to use it
Just two clicks:
- Pick your birth date (the red star marks it as required).
- Choose an “as of” date — leave empty for today.
- Hit Calculate age and boom — your age in years, months, and days appears.
🎯 Perfect for age verification, anniversary prep, or simply smiling at how many days you’ve been around.
*The calculator uses your local timezone, so the result is always right for where you are.
💡 Everything runs on your device – we never see your birth date. Because your privacy matters.
