How to get the day of the week from the day number in JavaScript?

Given dayNumber is from 0 - 6 representing Monday - Sunday respectively.

Can the Date / String objects be used to get the day of the week from dayNumber?

Solution

  • This will give you a day based on the index you pass:

    var weekday=new Array(7);
weekday[0]="Monday";
weekday[1]="Tuesday";
weekday[2]="Wednesday";
weekday[3]="Thursday";
weekday[4]="Friday";
weekday[5]="Saturday";
weekday[6]="Sunday";
console.log("Today is " + weekday[3]);

    Outputs "Today is Thursday"

    You can alse get the current days index from JavaScript with getDay() (however in this method, Sunday is 0, Monday is 1, etc.):

    var d=new Date();
console.log(d.getDay());

    Outputs 1 when it's Monday.
