Add day to date with momentjs

Question

I am trying to add a day to my date:

let createdDate = moment(new Date()).utc().format();

let expirationDate = moment(createdDate).add(1, 'd');

console.log(expirationDate);

However, this keeps returning an obscure object {_i: "2017-12-20T21:06:21+00:00", _f: "YYYY-MM-DDTHH:mm:ss Z", _l: undefined, _isUTC: false, _a: Array(7), …}

Does anyone know what I might be doing wrong?

Answer 1

You are logging a moment object. As the Internal Properties guide states:

To print out the value of a Moment, use .format(), .toString() or .toISOString().

let createdDate = moment(new Date()).utc().format();
let expirationDate = moment(createdDate).add(1, 'd');
console.log(expirationDate.format());

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.min.js"></script>

Please note that you can get the current date using moment() (no need to use new Date()) or moment.utc().

Answer 2

I will go with this one, simple works for me and I don't think you need other function to only add day in moment.

var yourPreviousDate = new Date(); var yourExpectedDate = moment(yourPreviousDate).add(1, 'd')._d;
