Revolution Slider for WordPress – Setting Starting/Expiration Date on Slides

Log in to wp-admin with your user name and password.
In the dashboard, click on “Revolution Slider”.
Select “Edit slides”, and then select “Edit Slide” on whichever one you want.
After loading, you can select “Visible from” field to set a starting date. (You can select a slide in there that will be shown in the future.)
Create an expiration date by entering the date in the “Visible until” field.
Select “Update slide” at the bottom of the page and the slide will now no longer be visible when it hits the entered date.
