UI5 OverlapCalendar Issue - datetime

Question

I got strange some issue with using OverlapCalendar. I thought it was due to daylight savings, because my input is 28 of march but it gets colored on 27 of march ( what should be weekend ) and then 1 of april is shown as nonworking day. Did anyone else experienced the same problem and behavior ?
Please find below my code.
sap.ui.jsview("calendartest.CalendarView", {
/** Specifies the Controller belonging to this View.
* In the case that it is not implemented, or that "null" is returned, this View does not have a Controller.
* #memberOf calendartest.CalendarView
*/
getControllerName : function() {
return "calendartest.CalendarView";
},
/** Is initially called once after the Controller has been instantiated. It is the place where the UI is constructed.
* Since the Controller is given to this method, its event handlers can be attached right away.
* #memberOf calendartest.CalendarView
*/
createContent : function(oController) {
var oModel = new sap.ui.model.json.JSONModel();
