Convert date from Day of Week to Day Name

Question

I'm using moment.js to manipulate my dates. I retrieve the data in which the field day is represented as numeral, like 1 for Monday, 2 for Tuesday and so on. How can I convert those int back to "Monday, Tuesday" etc using moment.js?

Answer 1

Use day(arg) method to retrieve the data object and then use format("dddd") to retrieve the day of week string.

 var date = moment(); let dayNumber = 4; let dayString = date.day(dayNumber).format("dddd"); console.log(dayString);

 <script type="text/javascript" src="https://rawgit.com/moment/moment/2.2.1/min/moment.min.js"></script>

Answer 2

You can have an array of strings with the days of the week in the order that you want:

    const daysOfWeek = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

    function getDayOfWeek(number){
        return daysOfWeek[number];
    }
