The category selection for an event post on the site automatically determines where the event post will appear on the site.
There are two category choices available for the event post: 'events' and 'upcoming events'.
The 'events' category is for past events. The information in a post with the 'events' category selected automatically moves that post to be presented with other past events. An event posted with the 'events' category may also be presented is a bottom section on the home page as well as a section on the events page. These event posts are automatically archived over time.
For an 'events' post (a past event), it is important to select a publish date that matches the event date for the automated posting to work properly. The publish date is located in the Publish box.
Contrastingly, a future event should use the 'upcoming events' category and the publish date should be the date one is posting the event and not the future date of the event. If one accidentally selects a future date for the Publish date, no harm is done, however, the Publish button turns into the Schedule button.
WHAT DO I DO ONCE THE FUTURE EVENT HAS BECOME A PAST EVENT?
Change the category of the post from 'upcoming events' to 'events', make sure the publish date matches the date the event was held and then click save or update. As an option, you can edit or update any information in the edit text box.
WHAT DO I DO IF I DON'T WANT THE PUBLIC TO VIEW ANY INFORMATION FROM A PAST EVENT?
You can trash the post. Trash means delete. Don't delete a post if you need the information at a later time, want to optimize search engine rankings, or desire the post to be archived.
WHAT DO I DO IF I WANT TO ARCHIVE A POST?
The system creates its own archive for any post with the category 'events'. You don't have to do anything. WordPress does it for you.
