Shortest one liner Change the UTC day from 6 to 5 if you want Array to start from Sunday   x000D   x000D  const getWeekDays    locale    gt      Array 7  keys    map  v   gt new Date Date UTC 1970  0  6 v   toLocaleDateString locale    weekday   long        console log getWeekDays  de-DE      x000D   x000D   x000D

Not the best method  use an array instead  This is just an alternative method   http   www w3schools com jsref jsref getday asp  var date   new Date    var day   date getDay      You should really use google before you post here   Since other people posted the array method I ll show you an alternative way using a switch statement   switch day        case 0          day    Sunday           break      case 1          day    Monday           break           rest of cases      default             do something         break      The above works  however  the array is the better alternative  You may also use if   statements however a switch statement would be much cleaner then several if s

var days          Sunday        Monday                etc      Saturday      console log days new Date   getDay        Simple  read the Date object in JavaScript manual  To do other things with date  like get a readable string from it  I use   var d   new Date    d toLocaleString      If you just want time or date use   d toLocaleTimeString    d toLocaleDateString      You can parse dates either by doing   var d   new Date dateToParse     or  var d   Date parse dateToParse

You could use the Date getDay   method  which returns 0 for sunday  up to 6 for saturday  So  you could simply create an array with the name for the day names   var days     Sunday    Monday    Tuesday    Wednesday    Thursday    Friday    Saturday    var d   new Date dateString   var dayName   days d getDay       Here dateString is the string you received from the third party API   Alternatively  if you want the first 3 letters of the day name  you could use the Date object s built-in toString method   var d   new Date dateString   var dayName   d toString   split      0     That will take the first word in the d toString   output  which will be the 3-letter day name
