Load php page via ajax, periodically

I want to load unlimited [login to view URL] to a div with unique id periodically, accordint to date/time. What I want is something like this: $date_time = xxx; #this is dynamic value with year, month, day, hour, minute if ($date_time = xxx1) { $( "#div" ).load( "ajax/[login to view URL]" ); } if ($date_time = xxx2) { $( "#div" ).load( "ajax/[login to view URL]" ); } ... and so on I need some freelancer that can start the project and complete it quickly.
