undefinedInvalid date

[raupie]

I'm not sure what I'm doing wrong but the custom range is throwing a invalid date NaN.

$('input[name="daterange"]').daterangepicker({
	opens: 'right',
	locale: {
		format: 'MM/DD/YYYY'
	}
}, function(start, end, label) {
	console.log("A new date selection was made: " + start.format('YYYY-MM-DD') + ' to ' + end.format('YYYY-MM-DD'));
});

yarn list --depth=0 | grep jquery@
├─ [email protected]
yarn list --depth=0 | grep moment@
├─ [email protected]
yarn list --depth=0 | grep daterange
├─ [email protected]

How is the start and end date determined? Could it be an issue with another library I'm utilizing?

So it's something with my environment or I don't have the correct dependencies.

Found the culprit in another JS file.

moment.updateLocale(moment.locale(), {
    week: {
	dow: CalendarFirstDayOfWeek
    }
});

Fixed via a firstDay option.

locale: {
    "format": 'MM/DD/YYYY',
    "firstDay": 1
},
