How to fix the javascript Date object

Question

I have a website with an automatic updating footer, where you can find the date. But the footer gives the complete wrong date. This is the code behind it:

$(function(){
    var now = new Date();
    var mm = now.getMonth() + 1;
    $("#footer").html(`&copy; NekoLuka ${now.getFullYear()}/${mm}/${now.getDay()}`);
}

Today is 2018/10/24, But the footer gives 2018/10/3.

Does anyone know how to solve this?

Your first stop should be [the documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getDay), which tells you that `getDay` returns the **day of the week**. You're looking for [`getDate`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getDate), which returns the day of the month. — T.J. Crowder, Oct 24 '18 at 12:08

Look at the documentation on MDN.

You are using getDay:

Returns the day of the week (0-6) for the specified date according to local time.

You should be using getDate:

Returns the day of the month (1-31) for the specified date according to local time.

now.getDay() gets the date of the week, you need now.getDate() to get the current day

The date is coming wrong because you are using getDay to get current date instead of getDate

replace now.getDay() with now.getDate()

The problem was that I used the getDay() instead of the getDate(). When I used the getDate(), the script worked.
