Show only 5 Days in Default-Calendar View (Mo-Fr)

I just had the requirement to Show only Monday to Friday in the Calendar View. The Environment was SharePoint 2010, I only had rights to edit the User Interface.

So I added a CEWP, which is linked to a Textfile located in a doc-Library, containing the following Script. The Script is overwriting some Default-Functions, which are responsible for Rendering. Besides some specific Appointments, starting with a specified String are rendered with additional attributes and it is showing all appointments (no expand/collapse anymore)

The Script is using some functions of (an old verions) of JQuery, because it is already loaded on the site. However, it might not be very difficult, to replace that functions into a native-way, if you don´t have JQuery.

The Content of my script-File:

<script language="javascript">
ExecuteOrDelayUntilScriptLoaded(function() {
//Removing Weekend and adjusting the calculated width of appointments
$('th.ms-acal-week-top').css('width', '20%');
$('th.ms-acal-month-top').css('width', '20%');
$('table.ms-acal-month tr').each(function(index) {$(this).find('td:gt(4), th:gt(5)').remove()});
SP.UI.ApplicationPages.CalendarTableBase.prototype.$3T = function(c,d){
        ULSvSp:;
        for(var b=0,a=0;
        a<d && a < 5;
        a++)b+=this.$1o(c+a);
        return b;
    }

SP.UI.ApplicationPages.CalendarTableBase.prototype.get_$2f = function(){
        ULSvSp:;
        return 5;
};

SP.UI.ApplicationPages.CalendarStateHandler.prototype.onTableSucceed =function(a){
        ULSvSp:;
        this.$D_1.$4V();
        this.$3H_1=false;
        a.Options&2&&this.$D_1.$7s(a.Table);
 $('table.ms-acal-detail tr').each(function(index) {$(this).find('td:gt(4), th:gt(5)').remove()});
        a.Options&8&&a.Options&32&&this.$D_1.$86(a.Dates,a.RangeJDay);
        this.$D_1.$7Z(this.$a_1.get_$2C());
        this.$2c_1=false;
        0===(a.Options&1)&&this.$2A_1()
};
//set all days to "Expanded"
SP.UI.ApplicationPages.CalendarInfoGrid.prototype.$38_0 = true;
//Applying specific background-color for all appointments starting with "Absenz"
SP.UI.ApplicationPages.ItemBuilder.prototype.$4P = function($p0, $p1, $p2, $p3, $p4, $p5, $p6, $p7) {
        var $v_0 = $p1.$c;
        $p0.append('<div class=\"ms-acal-item');
        if (!$v_0.$N.primary) {
            $p0.append(' ms-acal-color');
            $p0.append($v_0.$N.color);
        }
        $p0.append('\" style=\"');
        this.$3j_0($p0, $p2, $p3, $p4, $p5);
        $p0.append('border-width:');
        $p0.append($p6);
 if ($v_0.$3R.match(/^absenz/i))
 {
  $p0.append(';background-color: pink');
 } 
        $p0.append(';\" title=\"');
        this.$4X_0($p0, $v_0);
        $p0.append('\"');
        this.$4D_0($p0, $p1.$2K);
        $p0.append('\">');
        $p0.append('<div class=\"ms-acal-mdiv\">');
        if ($p7) {
            this.$5Q_0($p0, $v_0);
        }
        this.$3N_0($p0, $v_0);
        if (!this.$5_0($v_0.$1G)) {
            $p0.append(' (');
            $p0.append($v_0.$1G);
            $p0.append(')');
        }
        $p0.append('</div></div>');
    }
}, "SP.UI.ApplicationPages.Calendar.js");
</script>

Don´t really know, if it works in SP 2013 too, but as SP2013 is doing the rendering also in JS, it might be not very different to the SP2010 solution
