moment.js, how to get day of week number
Define "doesn't work".
const date = moment("2015-07-02"); // Thursday Feb 2015
const dow = date.day();
console.log(dow);<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>This prints "4", as expected.
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<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>Seeing as I wrote this answer on a Tuesday, today this gives me a 2.
I think this would work
moment().weekday(); //if today is thursday it will return 4
You can get this in 2 way using moment and also using Javascript
const date = moment("2015-07-02"); // Thursday Feb 2015
const usingMoment_1 = date.day();
const usingMoment_2 = date.isoWeekday();
console.log('usingMoment: date.day() ==> ',usingMoment_1);
console.log('usingMoment: date.isoWeekday() ==> ',usingMoment_2);
const usingJS= new Date("2015-07-02").getDay();
console.log('usingJavaSript: new Date("2015-07-02").getDay() ===> ',usingJS);<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
