i made small fork pen: http://codepen.io/saar/pen/yywvpw?editors=101

basically code (for 20 min or less, runs every 5 min):

var interval = setinterval(function(){   var currenttime = date.now();   $(".pt-time>span").each(function(idx){     var prayertimestring = $(this).text();     var prayertime = new date();     var times = prayertimestring.split(":");     prayertime.sethours(times[0]);     prayertime.setminutes(times[1]);     var timeofprayerinms = prayertime.gettime();     var timedif = timeofprayerinms- currenttime;      if(timedif <= 20*1000*60 && timedif > 0){       $(this).closest(".pt-circle").addclass("closeprayertime");     }     else{       $(this).closest(".pt-circle").removeclass("closeprayertime");     }   }); },1000*60*5);
