Add a free time card calculator to your website

One line of code puts a working hours and overtime calculator on your page. Free, no account, no ads, nothing to update.

<iframe src="https://freetimecardcalc.com/embed/" title="Time card calculator" width="100%" height="900" style="border:0;max-width:720px" loading="lazy"></iframe>
<p style="font-size:13px">Time card calculator by <a href="https://freetimecardcalc.com/">Free Time Card Calculator</a></p>

On a narrow column (under about 500 pixels wide) change height="900" to height="1150" so nothing is cut off.
