What is the best way to automatically post and remove content to a website based on date?

For instance... i have an upcoming event box on my homepage... instead of manually updating the box a few times a month... is it possible to use a bit of jQuery to automatically post the latest upcoming event... when the events' date expires... i would like the next upcoming event to automatically take its place.


fyi - my site is a static html5 website. i am open for other suggestions as well. thanks.
