Displays a different home page based on the pages the user specified to show at different times of the day.
If there is a time period where no page has been assigned, it will use the page you select in Settings > Reading in the Your homepage displays option.
There are four ranges to specify a page: 
– morning 
– noon 
– afternoon 
– night 
However, each hour selection covers the entire day so you don’t have to select all four: you can select three ranges, or two, or one.

Time Based Content

Displays a different front page according to the time of the day.

Harpinder

This plugin is very useful for those who want to display their pages (on front end) from some specific date (start date) to some specific date (end date). It creates a meta box in Edit Page where Admin user can add start & end date/time. After End date has been passed, the page will expire and is saved as ‘draft’. Very fast, easy to use plugin for both single & multi site installation. It uses GMT time format.
