difference between two times in am/pm format in javascript

Question

I want find the difference between two time in the format of AP/PM in jquery.

i had tested many codes but can't find any solution.

One of my code is here.

var timeStart = new Date("01/01/2007 " + "05.00 AM").getHours();
var timeStartmin = new Date("01/01/2007 "  + "05.00 AM").getMinutes();
var timeEnd = new Date("01/01/2007 " + "10.30 PM").getHours();
var timeEndmin = new Date("01/01/2007 " + "10.30 PM").getMinutes();

timeStart     =   timeStart+"."+timeStartmin;
timeEnd     =   timeEnd+"."+timeEndmin;

var hourDiff = timeEnd-timeStart;    
alert(hourDiff);

but it doesn't works properly. Can any body give me an advise.

Answer 1

You initialize your dates incorrectly. This is how you should do it:

var timeStart = new Date("01/01/2007 " + "05:00 AM");
var timeEnd = new Date("01/01/2007 " + "10:30 PM");

var diff = (timeEnd - timeStart) / 60000; //dividing by seconds and milliseconds

var minutes = diff % 60;
var hours = (diff - minutes) / 60;

Then you can do with hours and minutes whatever you want.
