Assuming the times are always on the hour, then here is a function that will convert the input value you have to 24 hour:

function getHour24(timeString)

{

    time = null;

    var matches = timeString.match(/^(d{1,2}):00 (w{2})/);

    if (matches != null && matches.length == 3)

    {

        time = parseInt(matches[1]);

        if (matches[2] == 'PM')

        {

            time += 12;

        }

    }

    return time;

}

Then if you want to find the difference, just do:

var starttime =  getHour24($(#StartTime).val());

var endtime = getHour24(($(#EndTime).val());



var timeDifference = endtime - starttime;

Hope that helps!
