how can i implement functionality to change the logo,background,banner,header image according to date automatically in my wordpress plugin

i am creating a plugin which is for promotions..Like the user can add events(Diwali,Holi) etc. called promotions.For every promotion there are options to add the Logo,Header,Background Image with the From and To date..It is the time when the Promotion will be started,When the Dates will arrive it should implement these changes(Logo,banner etc.) to my site frontend.But found no hook in wordpress which can implement these changes automatically instead the use of shortcode or any editing in file.please help me out.this is the code of my frontend file

function run_me()
{
        $class_of_logo=get_option('logo_css_class');
        $class_of_background=get_option('background_css_class');
        $class_of_banner=get_option('banner_css_class');
        $class_of_header=get_option('header_css_class');

    //echo "i am working";

       $services_loop = new WP_Query(
        array(

            'post_status' => 'publish'
    ));
