.day() returns wrong day of month with Moment.js

I am using Moment.js to parse a string and get the day, month and year separately: 

var date = moment("12-25-1995", "MM-DD-YYYY");
var day = date.day();

However, day is not 25—it's 1. What is the correct API method?

The correct function to use is .date():

date.date() === 25;

.day() gives you the day of the week. This works similarly to javascript's .getDate() and .getDay() functions on the date object.

If you want to get the month and year, you can use the .month() and .year() functions.

This how to get parts of date:

var date = moment("12-25-1995", "MM-DD-YYYY");


if (date.isValid()) {


day = date.date();
console.log('day ' + day);


month = date.month() + 1;
console.log('month ' + month);


year = date.year();
console.log('year '+ urlDateMoment.year());


} else {
console.log('Date is not valid! ');
}

You can use moment().format('DD') to get the day of month.

var date = +moment("12-25-1995", "MM-DD-YYYY").format('DD');
// notice the `+` which will convert
// the returned string to a number.

Good Luck...

.day(), is getting the day number of the week which output values ( 1 - 7 ) starting from Monday.

If the day is

  1. Monday will output 1
  2. Tuesday will output 2
  3. Wednesday will output 3
  4. Thursday will output 4
  5. Friday will output 5
  6. Saturday will output 6
  7. Sunday will output 7

To get the day of the month as @David mentioned, you need to use .date() Ex:

const today = moment().date()
