Update date.js

[rahulsalokhe]

DD-MMM-YYYY (20-Apr-2020) format not Validated so I changed following code. Please re write if so

var year = date[$.inArray('YYYY', dateFormat)],
month = date[$.inArray('MM', dateFormat)],
monthFul = date[$.inArray('MMM', dateFormat)],
day = date[$.inArray('DD', dateFormat)];

            if (isNaN(month)) {
				var monthArr = ['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec'];
				month = ($.inArray(monthFul.toLowerCase(), monthArr)+1).toString();
			}
