Problem:  The publish/unpublish Scheduling Options are ignored for Events.

This is a known issue, and we are still looking for a fix.

Events cannot currently be set to be automatically published or unpublished on a date in the future. The only workaround is to save the events without publishing them, and manually publish the events later.

To create events in advance of the date you want them to appear on the site, uncheck the Publish box in the Publishing Options before submitting the event.

On the day you want the event(s) to appear on your website, go into Content administration, check the boxes for the "not published" events, and update their status to publish them.  To make it easy to find the unpublished events, use the filter to display only events which are "not published".
