Thank you for contacting Syncfusion support.
Yes, it is possible to add week number in month view and the sample can be download from the below location.
Kindly find the below code example used in the sample.
<Code>
function onCreate() {
var obj = $("#Schedule1").data("ejSchedule");
if (obj.currentView() == "month") {
Date.prototype._getWeekNumber = function () {
var weekNo = Math.ceil((((this - new Date(this.getFullYear(), 0, 1)) / 86400000) + new Date(this.getFullYear(), 0, 1).getDay() + 1) / 7);
return (weekNo > 52) ? weekNo - 52 : weekNo;
};
var result = $.grep($(".cusRow"), function (value) { if ($(value).hasClass("cusRow")) { return value; } });
if (result.length != 0) $(".cusRow").remove();
var date = new Date(obj.currentDate());
var weekFirst = new Date(date.getFullYear(), date.getMonth(), 1);
var $tr = "<tr class='cusRow'>";
Date.prototype._currentWeekDates = function (firstdayofweek) {
var dayDiffer = this.getDay() - firstdayofweek,
start = new Date(this.getFullYear(), this.getMonth(), this.getDate() + (((dayDiffer < 0) ? dayDiffer + 7 : dayDiffer) * -1)),
end = new Date(start.getFullYear(), start.getMonth(), start.getDate() + 6);
return { start: new Date(start), end: new Date(end) };
};
for (var a = 0, len = obj._dateRender.length / 7 ; a < len; a++) {
var weekDate = weekFirst._currentWeekDates(obj._firstdayofweek);
var weekNumber = weekDate.start._getWeekNumber();
var count = 0, total = ((weekDate.end - weekDate.start) / (1000 * 60 * 60 * 24)) + 1;
for (b = 0; b < total; b++) {
if (obj.monthDays.indexOf(weekDate.start.getTime() + (1000 * 60 * 60 * 24 * b)) != -1) count++;
}
$tr += "<td colspan='" + count + "' style='padding:5px;border-left:1px solid #c3c3c3;border-bottom:1px solid #c3c3c3;text-align: center;'>" + weekNumber + "</td>";
weekFirst = new Date(weekDate.end.getTime() + (1000 * 60 * 60 * 24));
}
$tr += "</tr>";
$($tr).insertBefore(obj.element.find(".e-headerdays").find("tr:first"));
obj.element.find(".cusRow").children().first().css("border-left","none");
obj.refreshScroller();
}
}
</Code>
