Frequently asked questions
How are leap years and Feb 29 birthdays handled?
Month lengths and leap years are counted exactly. If you were born on February 29, your birthday is counted on February 28 in years that are not leap years.
How accurate is the result?
It counts whole calendar days, so daylight saving and time zones never shift the answer. The hour total is days multiplied by 24, counted from midnight. Nothing you enter leaves your browser.
Are my files uploaded anywhere?
No. Age Calculator runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Age Calculator really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
