The plugin allows to change theme (template) on desired dates. 
If you want a Christmas theme automatically on your blog just for 5 days (or more), the plugin will do it for you.
Just enter a start date, an end date , select times and the theme which you want to use, that’s it.
You can have as many combinations as you wish.
A theme for each seasons, halloween theme, christmas theme… or even a day and night theme…
<h3>Admin Panel</h3>
The admin panel will allow to move re-order your theme changes. 
Just remember that, the top is the lowest and the bottom is the highest level. 
So, if you have a theme change (‘theme1’) set for the 23/07 – 01/08 first and theme change (‘theme2’) for the 24/07 – 26/07, and today’s date is 24/07, 
‘theme2’ will be displayed unless you move down ‘theme1’.”
The rules, which you have created, will stay year on year.
