[date] moment.js, how to get day of week number

I have a moment date object, and want to get the selected day number (0-6) or (1-7).

I tried this, but it doesn't work

var aaa = moment(date).day();

help me with this please

From the docs page, notice they have these helpful headers

http://momentjs.com/docs/#/get-set/weekday/
(I didn't see them at first)

With header sections for:

• Date of Month
• Day of Week
• etc

.

  var now = moment();
  var day  = now.day();
  var date = now.date(); // Number

I think this would work

moment().weekday(); //if today is thursday it will return 4

If you are specifically looking for the 1-7 approach...

This is the ISO weekday number. moment.js has also taken this into account. Use isoWeekday()

console.log(moment().isoWeekday()); // returns 1-7 where 1 is Monday and 7 is Sunday

Seeing as I wrote this answer on a Tuesday, today this gives me a 2.

You can get this in 2 way using moment and also using Javascript

const date = moment("2015-07-02"); // Thursday Feb 2015_x000D_
const usingMoment_1 = date.day();_x000D_
const usingMoment_2 = date.isoWeekday();_x000D_
_x000D_
console.log('usingMoment: date.day() ==> ',usingMoment_1);_x000D_
console.log('usingMoment: date.isoWeekday() ==> ',usingMoment_2);_x000D_
_x000D_
_x000D_
const usingJS= new Date("2015-07-02").getDay();_x000D_
console.log('usingJavaSript: new Date("2015-07-02").getDay() ===> ',usingJS);
