MomentJS: how to parse dates in MM/DD/YYYY & DD/MM/YYYY

Question

How can i use moment.js in both: Australia & USA time formats?

For example:

07/08/2017 - is good for both time formats, but!

30/08/2017 - is invalid for moment.js, but i can have such dateTime

Answer 1

The parser is assuming that digits of the form XX-XX-XXXX are representing DD-MM-YYYY. If you'd like it to accept MM-DD-YYYY then you need to specify this.

eg var now2 = moment('08/30/2017', 'MM-DD-YYYY').format('MMM DD h:mm A');

You can also specify an array of different formats that you'd like it to accept so that it will recognise both:

var now2 = moment('08/30/2017', ['DD-MM-YYYY', 'MM-DD-YYYY']).format('MMM DD h:mm A');

Answer 2

Specify the format via a second parameter to the moment call

var now2 = moment('30/08/2017', 'DD/MM/YYYY').format('MMM DD h:mm A');

Otherwise there is no way for moment to know
