I just found out about this. Looks helpful and easy to use.  http://wpredirector.com ”This software allows you to “chain together” as many redirects as you want – based on time and date.

It’s simple! Just install this plugin on a WordPress site, create a new page or post, then click “add a redirect” below the page/post visual editor…and select the date and fill in the URL to redirect to.

If you’re done then just click “publish” on the post or page. If you want to add more, simply click “add a redirect” again. Chain together as many time based redirects as you desire.”
