React-Native Moment returns wrong day

Question

I’m using Moment in a project with React Native.

And a specific date it does not return the correct day, all the others returns right. I put it in the index.js of the application to see if any instance somewhere was not getting in the way, but still it returns wrong.

import { AppSrc } from './src/containers/App';
import moment from 'moment';

const day = moment('2019-02-17', 'YYYY-MM-DD').format('DD');
console.log('-> MOMENT -> INDEX', day); // '-> MOMENT -> INDEX', '16'

new AppSrc();

Does anyone have any idea what might be causing this?

UPDATE

solved in this way

import moment from 'moment';
import 'moment-timezone';
import 'moment/locale/pt-br';

moment.tz.setDefault('UTC');
moment.locale('pt-BR');

Answer 1

I believe it may be because there are missing parameters when you pass the "const day". Try as follows:

const day = moment('2019-02-17', 'YYYY-MM-DD', true).format();

If this doesn’t help solve the problem you can read about it here:

I hope I’ve helped.
