    Hi please help me with this website. This website is used to list 6 events and then it should accurately countdown to when that event happens. As it is right now it accurately counts days, but hours, minutes, and seconds are counted down incorrectly. Here is the js file:

    Function List:
    Returns the date in a text string formatted as:
    mm/dd/yyyy at hh:mm:ss am

    changeYear(today, holiday)
    Changes the year value of the holiday object to point to the
    next year if it has already occurred in the present year

    countdown(stop, start)
    Displays the time between the stop and start date objects in the
    text format:
    dd days, hh hrs, mm mins, ss secs

    function showDateTime(time) {
    date = time.getDate();
    month = time.getMonth()+1;
    year = time.getFullYear();

    second = time.getSeconds();
    minute = time.getMinutes();
    hour = time.getHours();

    ampm = (hour < 12) ? " a.m." : " p.m.";
    hour = (hour > 12) ? hour - 12 : hour;
    hour = (hour == 0) ? 12 : hour;

    minute = minute < 10 ? "0"+minute : minute;
    second = second < 10 ? "0"+second : second;

    return month+"/"+date +"/"+year+" at "+hour+":"+minute+":"+second+ampm;

    function changeYear(today, holiday) {
    var year = today.getFullYear();
    year = (today > holiday) ? year + 1 : year;
    year = holiday.setFullYear(year);

    function countdown(start, stop){
    time = stop - start;
    var rawdays = ((time)/(1000*60*60*24));
    days = Math.floor(rawdays); //milisec/sec*sec/min*mins/hour*hours/day is what's divided 4 value
    var rawhours = ((rawdays - days)*24) - 1;
    hours = Math.floor(rawhours);
    var rawminutes = (rawhours - hours)*60;
    minutes = Math.floor(rawminutes);
    var rawseconds = ((rawminutes - minutes)*60) + 1;
    seconds = Math.floor(rawseconds);

    return days + " days, " + hours + " hours, " + minutes + " mins, " + seconds + " secs";

    Please tell me what I need to do to make all of them countdown properly and tell me what technique I can use in the future to do this for future websites in case I need to countdown to 30 events. I would appreciate any help.
