    var now = new Date();
    var month = '' + (now.getUTCMonth() + 1);

    if (day.length &lt; 2) day = '0' + day;

    if (hour.length &lt; 2) hour = '0' + hour;
    if (minute.length &lt; 2) minute = '0' + minute;

And to parse a string to date.

function stringToDate(dateString, format, delimeter) {
    var formatLowerCase = format.toLowerCase();
    var formatItems = formatLowerCase.split(delimeter);
    var dateItems = dateString.split(delimeter);
    var monthIndex = formatItems.indexOf("mm");
    var dayIndex = formatItems.indexOf("dd");
    var yearIndex = formatItems.indexOf("yyyy");
    var month = parseInt(dateItems[monthIndex]) - 1;
    return new Date(dateItems[yearIndex], month, dateItems[dayIndex]);
}

stringToDate("27/2/2018", "dd/MM/yyyy", "/");
stringToDate("2/27/2018", "mm/dd/yyyy", "/");
stringToDate("2-27-2018", "mm-dd-yyyy", "-");
