            data: JSON.stringify({ Booker: BookedBy, Mnyear: monyear }),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            async: false,
            success: function (response) {
                $.each(response.d, function (index) {
                    newFeeds1.push({
                        id: response.d[index].id,
                        name: response.d[index].name,
                        location: response.d[index].location,
                        // startDate: new Date(response.d[index].startDate.substring(7,11), month.indexOf(response.d[index].startDate.substring(3,6)), response.d[index].startDate.substring(0,2)),
                        //endDate: new Date(response.d[index].endDate.substring(7,11), month.indexOf(response.d[index].startDate.substring(3,6)), response.d[index].endDate.substring(0,2))
                        startDate: new Date(response.d[index].stYear, response.d[index].stMon - 1, response.d[index].stDay),
                        endDate: new Date(response.d[index].edYear, response.d[index].edMon - 1, response.d[index].edDay),
                        CreatedRole: response.d[index].CreatedRole
                    })

                });
            },

document.querySelector('.calendar').addEventListener('yearChanged', function (e) {
console.log("New year selected: " + e.currentYear);
load_data(e.currentYear);
//$('#calendar').data('calendar').setDataSource(newFeeds1);

        calendar = new Calendar('#calendar', {
            dataSource: newFeeds1
        });
