What the Widget Does

• Calculates exact age in years, months, and days from any date of birth.
• Shows total days, weeks, and months lived, plus a countdown to the next birthday.
• Uses the same calculation method as our main age calculator, including leap years.
• Resizes to fit your column on desktop and mobile, up to 420 pixels wide.
• Runs entirely in the visitor's browser. The widget contains no ads, no analytics, and sets no cookies.

Frequently Asked Questions

Is the widget really free?

Yes. You can use it on personal, school, nonprofit, and commercial websites at no cost. We only ask that you keep the short credit line under the calculator.

Can I change the size?

Yes. The widget adapts to narrower spaces automatically. If your theme adds extra spacing, you can increase the height value in the code.

Will it slow down my site?

No. The widget is a single lightweight page with no external scripts, and the code uses lazy loading, so it only loads when a visitor scrolls to it.

Does it collect my visitors' data?

No. Dates entered into the widget are calculated in the visitor's browser and are not sent to us. See our Privacy Policy for details about the main website.

Something isn't working. How do I get help?

Email support@agecalculator.live with the address of the page where you added the widget.
