    Hi

    Just subtract the earlier datetime value from the later datetime value. This would give you the value in millisecond. Get the hours from this.

    Example (you refer the following code, obtain the values from the 'Date and Time' fields in the form using Xrm.Page.getAttribute and subtract the earlier date from the later date):

            var startDateTime = new Date(2007, 8, 25, 22, 25, 26, 456);
        var endDateTime = new Date(2017, 8, 25, 22, 25, 26, 457);
        var duration = (endDateTime - startDateTime)/36e5;//returns the difference in hours

    Hi Dinoop,

    1. You should get the Datetime field by CRM SDK
    var dateTime1 = Xrm.Page.getAttribute("datetime1Field_name").getValue();
    var dateTime2 = Xrm.Page.getAttribute("datetime2Field_name").getValue();

    2. calculate the difference

    dateTimeDiff = dateTime1 - dateTime2;
    var diffhours = (dateTimeDiff /1000) / 3600;
    // alert(diffhours);

    Please mark correct if it help you :)
