The .length operator doesn't return the number of days in the month, that is more for arrays and strings.

What you need is to take advantage of the Date object constructor!

function getDaysInMonth(year, day) {
    return new Date(year, day, 0).getDate();
}

Just pass in your date object before console.log, like this

console.log( getDaysInMonth( Date().getYear(), mymonth) );

You need to parse the date/month to string coz by default it gives an integer value and length property only work with string , object or array types ! 

var mymonth=String(new Date().getMonth());
console.log(mymonth.length);

will give you 1 as a o/p

getMonth returns int value and it does not have length property. You need to make it string first and then call length.

var mymonth=new Date().getMonth();
console.log(mymonth.toString().length);

mymonth is a numerical value which does not have the length property, so try

var mymonth=new Date().getMonth();
console.log((''+ mymonth).length);

or use a numerical comparison like below to check whether the month is of 2 digits or not

mymonth < 10

Try this

var mymonth=new Date().getMonth();
alert((mymonth).toString().length);

You need to convert the date value to string and then count the length. Try this:

var mymonth=new Date().getMonth();
console.log(mymonth.toString().length);

It is in date format so you convert to string first and count the length.Use .toString() in javascript

var mymonth=new Date().getMonth();
console.log(mymonth.toString().length);
