edit the calendar on schedule

I add a canlendar on schedule that to select the working day. But I want to edit the calendar. By default, the start day is monday. I want to change the starting day is sunday.
The calendar is on schedule

I want to ask how change the starting day format ?

The following code is to add the calendar on schedule.



<div class="dhx_cal_navline">
<div class="dhx_cal_date"></div>
<div class="dhx_minical_icon" id="dhx_minical_icon" onclick="show_minical()">&nbsp;</div>



  function show_minical() {
                if (scheduler.isCalendarVisible())
                    scheduler.destroyCalendar();
                else
                    scheduler.renderCalendar({
                        position: "dhx_minical_icon",
                        date: scheduler._date,
                        navigation: true,
                        handler: function (date, calendar) {
                            scheduler.setCurrentView(date);
                            scheduler.destroyCalendar()
                        }
                    });
            }
