<p>Google offers some HTML snippets to embed your public Google Calendar into your website. These are great, but as soon as you want to make a few adjustments to the styling, that goes beyond changing some colors, they’re useless. Because of that I wrote a very simple widget, that fetches events from a public google calendar and nicely displays them in form of a widget, allowing you to apply all kinds of CSS. The source code should be quite easy to modify.</p>
