This plugin provides shortcodes allowing you to display content or hide content at given dates and times. You can also combine the two to show some content at a given time, and then hide it at another time.
There's also a separate shortcode if you want to repeat a schedule for showing and hiding content - for example to only show information about a radio show while it's on air.
If you find an issue, let me know here.
