How to get day name in a date in node js

Question

I have a date like this

2017-06-23 and my desired output is

Friday June 23 2017

 v.npi.appointment_dates[j] = date.toLocaleString('en-US', {year: 'numeric', month: 'long', day: 'numeric' });

But because of the day: 'numeric' I am missing the day name. Can anyone please help me?

Have a look at the Date object and construct it on your own... — Jonas Wilms, Jun 29 '17 at 13:28

It's not because of `day: 'numeric' `, it's because you've omitted `weekday: 'long'`. — RobG, Jun 29 '17 at 22:32

You need to include weekday: 'long' in the options object:

var date = new Date();
console.log(date.toLocaleString('en-US', {
      weekday: 'long',
      year: 'numeric',
      month: 'long',
      day: 'numeric'
    }));

If you want to adopt the the browser default language, use undefined:

var date = new Date();
console.log(date.toLocaleString(undefined, {
      weekday: 'long',
      year: 'numeric',
      month: 'long',
      day: 'numeric'
    }));

Even with options support, the result of toLocaleString is still implementation dependent as the "locale" option is actually a language code, which may not be what the user expects even if they speak that language and the browser developers may not have chosen the expected format.

Here is the function you're looking for.

function getFormattedDate(date) {
  var dayNames = ['Monday', 'Thursday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
  var monthNames = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']

  var dayOfMonth = date.getDate()
  var dayOfWeekIndex = date.getDay()
  var monthIndex = date.getMonth()
  var year = date.getFullYear()

  return dayNames[dayOfWeekIndex] + ' ' + monthNames[monthIndex] + ' ' +  dayOfMonth + ' ' + year;
}

You should take a look at moment.js which will help you a lot with formatting and tons of other date issues.

I would add +1 do the dayOfWeekIndex – Sebastian Feb 14 '21 at 12:21 — Sebastian, Feb 14 '21 at 12:21
