Looking for display and hide

I understand. This plugin was made with a programmer(me) in mind. If you didn’t find any alterantives here’s the code you could add inside the function.php of your theme (I recomend making a child theme, you can find plugins for this also):

add_filter( "eleconditions_vars",function($custom_vars){
	$currenttime=date("H:i:s");// the format is only for time... not for date and it looks like 17:00:00
	if ("07:00:00" < $currenttime and $currenttime < "19:00:00"){ // the interval between 7am and 7pm of each day... if you want a specific date you add the entire format (2018-11-04 00:00:00) : date("Y-m-d H:i:s");
		$custom_vars['intimeframe']=true;
	}
	return $custom_vars;
});

and if condition you can add:

intimeframe === true

Hope this would help you.
