How to embed
Copy and paste this snippet into your blog post HTML. The iframe auto-resizes and works on mobile.
Standard embed (responsive)
<iframe src="https://calccentral.net/embed/date-duration" width="100%" height="380" frameborder="0" style="border:0;max-width:480px;" title="CalcCentral Date Duration"></iframe>
Tall variant (with embed attribution)
<iframe src="https://calccentral.net/embed/date-duration?branded=1" width="100%" height="416" frameborder="0" style="border:0;max-width:520px;" title="CalcCentral Date Duration"></iframe>
Backlink appreciated but not required. The widget shows a small “by CalcCentral” attribution when ?branded=1 is set.
